The Delta III Lithotripter is indicated for the fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones.
The Delta III Lithotripter is a modular urological work station designed for extracorporeal shock wave lithotripsy ("ESWL") and for diagnostic and therapeutic procedures usual in urology. The Delta III is composed of the following modules: Basic Unit with integrated X-ray C-arm and Therapy Arm with camera for Shockwave Treatment; Patient Table; Control Desk/Image Storage (UIMS).
This document is a 510(k) summary for the Delta III Lithotripter, detailing minor changes to an existing device. As such, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with acceptance criteria and a human-in-the-loop performance evaluation. The information provided primarily consists of engineering and software validation.
Here's an analysis based on the provided text, addressing your questions to the extent possible:
1. Table of acceptance criteria and the reported device performance
The document does not present a formal table of acceptance criteria for clinical performance in the way one might expect for a new diagnostic or AI device. Instead, the "acceptance criteria" are implied by compliance with standards and functional validation tests, with the reported performance being "does not impact the performance" and "equal to or better than the predicate."
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Standards Compliance: | |
| IEC 60601-1 (Electrical safety) | Compliant |
| IEC 60601-1-2 (EMC) | Compliant |
| IEC 60601-1-3 (Radiation protection) | Compliant |
| IEC 60601-2-36 (Lithotripsy safety) | Compliant |
| IEC 60601-2-28 (X-ray tube assemblies) | Compliant |
| IEC 60601-2-54 (X-ray equipment safety) | Compliant |
| IEC 62366-1 (Usability engineering) | Compliant |
| IEC/TR 62366-2 (Usability guidance) | Compliant |
| Bench Testing (Functional Validation): | |
| New ultrasound device provides visual and accurate images for stone visualization | Performance assured; provides visual and accurate images |
| New camera image quality is equal to or better than the predicate | Image quality equal to or better than the predicate |
| UIMS software with AGFA package does not impact equipment functioning and processes X-ray images | Does not impact functioning; provides ability to further process X-ray images |
| Electrical safety, EMC, functional usability are fully addressed | Demonstrated compliance with standards and equivalent performance to predicate |
| No unanticipated new risks identified | No unanticipated new risks identified |
2. Sample size used for the test set and the data provenance
The document describes bench testing and standards compliance, not a clinical test set with patient data. Therefore, there is no mention of a "sample size for the test set" in the context of patient data, nor its provenance (country of origin, retrospective/prospective). The tests mentioned are engineering and software validation tests.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This type of information is not applicable to the submission described. The described tests are about technical performance, safety, and functionality, not about expert interpretation of medical images or patient outcomes. Ground truth in this context would refer to engineering specifications or validated functional requirements.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable as the submission describes engineering and software validation, not a clinical study requiring adjudication of diagnoses or findings.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No MRMC comparative effectiveness study was done or is mentioned. The submission is for minor changes to an existing lithotripter, focusing on hardware component replacements and software updates, not AI integration for improved human reading.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device (Delta III Lithotripter) is a medical device for shock wave lithotripsy. While it includes image processing software (UIMS with AGFA MUSICA), the evaluation described is for the functional performance of these components within the overall system, not a standalone algorithm being evaluated for diagnostic accuracy without human involvement. The AGFA MUSICA software enhances X-Ray image processing, but it's part of the lithotripter system for visual guidance during procedures, not a diagnostic AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the described tests, the "ground truth" would be established by:
- Engineering specifications and regulatory standards: For electrical safety, EMC, radiation protection, and usability.
- Predicate device performance: For the ultrasound image quality and camera image quality, the ground truth for comparison is the performance of the components being replaced.
- Functional requirements: For the UIMS software validation, the ground truth is that the software should perform its intended function (e.g., image processing, PACS connection) without negatively impacting other equipment functions.
There is no mention of expert consensus, pathology, or outcomes data being used as ground truth for these specific validation tests.
8. The sample size for the training set
Not applicable. This submission does not involve a machine learning or AI model that requires a training set in the conventional sense. The UIMS software update involves incorporating the AGFA MUSICA package, which is likely a pre-existing, validated image processing software, not a custom-trained model for this specific application.
9. How the ground truth for the training set was established
Not applicable, as there is no mention of a training set.

The Delta III Lithotripter is indicated for the fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones.
The Delta III Lithotripter is a modular urological work station designed for extracorporeal shock wave lithotripsy ("ESWL") and for diagnostic and therapeutic procedures usual in urology.
The Delta III is composed of the following modules:
- . Basic Unit with integrated X-ray C-arm and Therapy Arm with camera for Shockwave Treatment;
- Patient Table;
- . Control Desk - Image Processing.
The basic unit contains the power supplies, control unit, power electronics for motor drives, components for shockwave generation, and an integrated Therapy C-arm and an X-Ray C-Arm. The housing can be positioned with its back close to the room wall and has wide side doors for easy service.
The therapy and X-Ray C-arm house the shock wave source ("EMSE") and the complete Xray unit. The X-ray unit consists of the X-ray generator, the X-ray tube, an image receptor system, and a high resolution imaging chain. This provides the imaging to perform the procedures. The C-arms allow for a wide range of movement to facilitate performing urological procedures. The shock wave circuit supplies the shock wave energy needed for the treatment of kidney stones.
The Delta III's urological patient table provides longitudinal, lateral and vertical travel range to allow easy positioning of the stone in the shock wave focus for lithotripsy and urological procedures.
The image processing system (UIMS) with DICOM 3 capability supports PACS connection and offers complete X-ray control and image handling.
This document describes a 510(k) submission for the Delta III Lithotripter, which is a modification to a previously cleared device. As such, the submission focuses on demonstrating substantial equivalence to the predicate device rather than conducting extensive new clinical studies to establish absolute performance against defined acceptance criteria for a novel device.
Therefore, the typical structure for reporting acceptance criteria and study details for a new device's performance may not be fully applicable here. However, I can extract the information provided regarding the changes and how their safety and effectiveness were addressed.

| Hand controller function | Verification of hand controller function testing was performed. |
| Ultrasound localization accuracy (with additional ultrasound units) | Engineering analysis concluded prior ultrasound localization accuracy testing supported compatibility. |
| No new unanticipated risks | No unanticipated new risks identified. |
| Maintains intended use, technological characteristics, and principles of operation of predicate | The modified Delta III has the same intended use, technological characteristics, and principles of operation as the predicate device. Minor differences do not alter intended use or affect safety/effectiveness. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document describes tests for compliance with electrical, EMC, radiation, and usability standards, as well as software and hardware verification. These are typically engineering and bench tests, not clinical studies with human subjects in the traditional sense. Therefore, the concept of "sample size used for the test set" for patient data, country of origin, or retrospective/prospective does not apply to the provided performance data. The tests performed are on the device itself.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This section is not applicable. The performance data provided is based on compliance with international standards and internal engineering verification, not on expert adjudication of clinical outcomes or images.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This section is not applicable, as the tests are for engineering compliance and verification, not for clinical outcomes requiring expert adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This section is not applicable. The device is a lithotripter, not an AI-assisted diagnostic tool for human readers. There is no mention of an MRMC study or AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This section is not applicable. The device is a physical medical device (lithotripter), not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the verification tests mentioned (e.g., electrical safety, software functionality), the "ground truth" is defined by the requirements of the applicable international standards (e.g., IEC 60601 series) and the design specifications of the device. For example, for electrical safety, the ground truth is compliance with the specified voltage limits or isolation requirements in the standard. For software, it's meeting the intended function and not introducing errors.
8. The sample size for the training set
This section is not applicable. The document describes a physical medical device and its modifications, not a machine learning or AI model that requires a training set.
9. How the ground truth for the training set was established
This section is not applicable for the same reason as point 8.

The Genesis II is a radiographic and fluoroscopy examination table with the X-ray tube housing mounted over the table on a fixed arm. An image intensifier is mounted underneath the patient table. While the X-ray tube and detector are fixed in their positions relative to each other when the system is in use, the table top and X-ray/detector unit can be moved in a variety of planes to position the patient in the desired imaging position.
The provided text describes the 510(k) premarket notification for the Dornier MedTech America, Inc. Genesis II device, an Image Intensified Fluoroscopic X-ray System. It focuses on demonstrating substantial equivalence to predicate devices rather than providing a detailed study proving the device meets specific quantitative acceptance criteria.
However, based on the information provided, we can infer some aspects and highlight what is missing.
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Acceptable diagnostic image quality for intended uses. | A board-certified radiologist evaluated a number of sample images obtained using the Genesis II and determined that the device output images were of acceptable diagnostic quality. |
| Compliance with relevant medical electrical safety standards. | The device is in compliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-1-6, IEC 60601-2-28, IEC 60601-2-54, and NEMA PS 3.1-3.20 (DICOM Set). |
| Not raising new questions of safety or effectiveness compared to predicate devices. | The use of a cleared image intensifier technology (identical to that in Dornier Gemini Lithotripter system K121656) in the Genesis II, which has similar indications for use to other FDA-cleared uroradiology systems (e.g., Urotract I K955019), does not raise any new questions of safety or effectiveness. The device has the same intended use and indications for use as the predicate Genesis system (K122768). |
2. Sample size used for the test set and the data provenance
- Sample Size for Test Set: The document states, "a board certified radiologist evaluated a number of sample images obtained using the Genesis II." A specific numerical sample size is not provided.
- Data Provenance: The origin of the sample images (e.g., country of origin) and whether the data was retrospective or prospective is not specified.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: "a board certified radiologist" — this suggests one expert.
- Qualifications of Experts: The expert was a "board certified radiologist." No further detail (e.g., years of experience) is provided.
4. Adjudication method for the test set
- "a board certified radiologist evaluated... and determined..." This indicates that the evaluation was performed by a single expert. There is no mention of an adjudication method involving multiple experts to establish ground truth or resolve discrepancies, as only one expert is noted.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC comparative effectiveness study was not done. The document describes the evaluation of image quality of the device itself, not the performance of human readers with or without AI assistance. This device is an imaging system, not an AI-based diagnostic tool for interpretation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- This question is not applicable as the Genesis II is an X-ray imaging system, not an algorithm or AI device that performs diagnoses independently. The evaluation described is for the diagnostic quality of the images produced by the hardware, which would then be interpreted by a human.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- The ground truth for the image quality assessment was established through expert opinion/evaluation by a single board-certified radiologist, who determined if the images were of "acceptable diagnostic quality." There is no mention of an objective reference standard like pathology or outcomes data.
8. The sample size for the training set
- The document implies that the device (Genesis II) itself was designed and verified against established engineering and safety standards, and its image intensifier technology is based on previously cleared devices. It does not describe a "training set" in the context of an algorithm or AI model. Therefore, this question is not applicable for this type of device submission.
9. How the ground truth for the training set was established
- As the concept of a "training set" for an algorithm is not applicable to this device, the establishment of its ground truth is not relevant in this context. The device's "training" in a functional sense would be its design, manufacturing processes, and adherence to established technical standards, as well as the prior clearance of its component technologies.

The Uropulse is intended to be used for cutting, vaporization, and coagulation of soft tissue in conjunction with endoscopic equipment (including laparoscopes, hysteroscopes, bronchoscopes, gastroscopes, cystoscopes, and colonoscopes), or for open surgery for contact or non-contact surgery with or without a handpiece for use in incision/excision, vaporization, ablation and coagulation of soft tissue. The Uropulse is indicated for use in medicine and surgery, in the following medical specialties:
- Arthroscopy .
- Urology .
- Lithotripsv
- Pulmonology
- Gastroenterology
- Gynecology
- ENT
- General Surgery
The Dornier Medilas D Uropulse Laser is a solid-state Holmium YAG Laser. The laser emits laser radiation in the invisible wavelength range of 2080 nm in either a continuous-wave or pulsed mode, which is absorbed primarily by water, with an average penetration depth of approximately 400μm (0.4mm). Due to the application-dependent optimization of the pulse time of 350 microseconds, the Uropulse can be used in various medical applications including breaking up stones, cutting tissue, tissue ablation, coagulation and vaporization.
The laser is microprocessor-controlled utilizing a watchdog-monitored microprocessor and operates with an internal cooling system and a heat exchanger. The bottom of the housing serves as a tank for cooling water and, at the same time, a base for the laser unit. A cooling circuit conducts away heat that is generated by the laser pump lamp. Water heated by the laser pump is conducted out of the cavity and into the stainless steel cooler. Following cooling, it is returned to the tanks.
A graphic control panel regulates and displays the operating parameters, application modes, time functions, system status and messages to the User. The control panel consists of a display with integrated touch screen panel applications to control the functions of the laser.
The laser light emission is transmitted to the application site by a sterile fiber optic delivery system (fiber cable) with a SMA 905 connector. Laser energy is transmitted through the fiber to the application site by depressing a foot pedal. The foot pedals, both the wired and wireless, are water- proof and explosion-proof. Various fiber sizes can be utilized depending on the application.
The laser pulse energy at the distal end of the fiber lies within the range of 200-3500mJ. The pulse frequency can be adjusted in 0.2Hz increments between 3 and 20 HZ. The Uropulse contains an aiming beam at a wavelength of 532nm at the maximum power aperture of 1mW. The device employs a Class IV (4) laser pursuant to 21 CFR 1040 and IEC/EN 60825-1.
The provided text is a 510(k) summary for a medical device called "Medilas H Uropulse," a Holmium: Yttrium Aluminum Garnet (HO:YAG) Laser System. It focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria through a detailed study.
Therefore, many of the requested categories related to acceptance criteria and specific study results (like sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and detailed ground truth for training/test sets) are not applicable or available in this type of submission.
Here's an analysis based on the available information:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|

The Dornier GENESIS is intended for use in a wide field of applications, including all general examinations in urology and gynecology, as well as endoscopic and contrast examinations, imaging with radiography and/or fluoroscopy on patients in either the horizontal or vertical position.
The Dornier GENESIS is an Image Intensified Fluoroscopic X-ray System (i.e., a solid state x-ray imager (flat panel/digital imager)). The GENESIS consists of the following components: an x-ray generator and tube housing, flat panel detector, monitors and procedure table. An X-ray cabinet contains system elements such as the X-ray generator, power electronics and electronics for the imaging chain.
The provided text describes the 510(k) summary for the Dornier GENESIS, an Image Intensified Fluoroscopic X-ray System. The documentation focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed acceptance criteria and a specific study proving the device meets them as would be found for an Artificial Intelligence/Machine Learning (AI/ML) device.
Here's an analysis based on the provided text, addressing the requested points. It's important to note that many of these points are not applicable or cannot be fully answered given the nature of the document (a 510(k) for a conventional medical imaging device, not an AI/ML device).
1. A table of acceptance criteria and the reported device performance
The document does not present a table of specific quantitative acceptance criteria or detailed reported device performance in terms of clinical outcomes or diagnostic accuracy. Instead, it states that the GENESIS was tested against recognized testing standards for medical electrical equipment and X-ray systems.
| Acceptance Criteria (Based on standards compliance and stated equivalence) | Reported Device Performance |
|---|---|
| Compliance with IEC 60601-1 (General safety) | Device functioned as intended. |
| Compliance with IEC 60601-1-2 (EMC) | Device functioned as intended. |
| Compliance with IEC 60601-1-3 (Radiation protection for diagnostic X-ray) | Device functioned as intended. |
| Compliance with IEC 60601-1-6 (Usability) | Device functioned as intended. |
| Compliance with IEC 60601-2-7 (Safety of high voltage generators) | Device functioned as intended. |
| Compliance with IEC 60601-2-28 (Safety of X-ray source assemblies) | Device functioned as intended. |
| Compliance with IEC 60601-2-54 (Safety and performance of X-ray equipment) | Device functioned as intended. |
| Compliance with FDA Guidance for Solid State X-ray Imaging Devices | All required nonclinical and clinical testing completed; results were as expected. |
| Equivalent performance to predicate Urotract | Concurrence study confirmed the GENESIS has at least equivalent performance. |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document mentions a "concurrence study" but does not provide details on the sample size used (number of patients or images). It also does not specify the data provenance (country of origin, retrospective or prospective nature).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not provided in the document. The nature of the device (a fluoroscopic x-ray system) suggests that evaluation would likely involve assessments of image quality and functionality by subject matter experts, but details are absent.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The document does not specify any adjudication method used for the test set in the concurrence study.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
A Multi-Reader Multi-Case (MRMC) comparative effectiveness study, particularly one measuring improvement with AI assistance, is not applicable to this device. The Dornier GENESIS is an X-ray imaging system, not an AI/ML diagnostic software. The "concurrence study" mentioned would have focused on comparing the performance of the GENESIS device itself against a predicate device, not on how human readers perform with AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This point is not applicable as the Dornier GENESIS is an imaging hardware system, not an algorithm or software that operates in a standalone manner.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The document does not explicitly state the type of ground truth used for the "concurrence study." Given it's an imaging device, ground truth would likely be established through a combination of clinical assessment, potentially comparison to higher-fidelity imaging, or follow-up outcomes, but no specifics are provided.
8. The sample size for the training set
This is not applicable. The Dornier GENESIS is an X-ray imaging system, not an AI/ML model that requires a training set.
9. How the ground truth for the training set was established
This is not applicable for the reasons stated above.

Summary for this specific device:
The regulatory approval for the Dornier Medilas H RFID Reusable Laser Fibers is based on demonstrating substantial equivalence to existing predicate devices (Dornier Medilas H RFID Laser Fiber K121938 and Dornier Medilas H Laser Fiber Cables K022544). The key modification is the addition of reprocessing instructions to allow for reusability. The "study" that proves the device meets acceptance criteria would be a series of performance tests confirming that the fibers maintain their safety and effectiveness (e.g., laser energy transmission, structural integrity, biocompatibility, and sterility after multiple reprocessing cycles) despite being reused and going through the specified cleaning and sterilization processes. The document states "Performance data demonstrates that the Dornier Medilas H RFID Reusable Laser Fibers are as safe and effective as the listed predicates," implicitly confirming that these tests were conducted and the criteria met, though the specific details of these tests (like sample sizes, methods, and acceptance thresholds) are not provided in this specific excerpt.
