The AMT Low-Profile Suprapubic Catheter & Drainage Set is indicated for patients 7 years of age and older with lower urinary tract dysfunctions such as neurogenic bladder dysfunction or urethral obstruction or who are severely disabled or requiring constant care. The AMT Low-Profile Suprapubic Catheter & Drainage Set is indicated to be used for temporary suprapubic urinary diversion and drainage for less than or equal to four weeks. The AMT Low- Profile Suprapubic Catheter is intended to be placed directly into the bladder through a secured (initial placement) or formed (replacement) stoma.
The Applied Medical Technology, Inc. (AMT) Low-Profile Suprapubic Catheter & Drainage Set (LPSPC) consists of two primary assemblies. The LPSPC is identical in materials and manufacturing processes to the Low-Profile Balloon Feeding Device cleared in K161413 for a different indication.
The Suprapubic Catheter is used to provide urinary diversion and drainage through the lower abdomen, placed and maintained in a percutaneously prepared cystostomy opening. The Drainage Set is intended to allow a connection between the suprapubic catheter device and a urinary collection bag system. The device is designed for bladder drainage by way of a secured (initial placement) or formed (replacement) cystostomy tract and may be used for irrigation. Patients may include: any user with urethral trauma, those who require long-term catheterization and urethral catheterization is intolerable, or those with a spinal cord injury and an inability to self-catheterize who may find the suprapubic method simpler to manage.
The LPSPC is a urinary drainage device made principally of silicone elastomer. The device consists of an internal retention balloon and a flexible external bolster with a balloon fill-valve, interlocking irrigation port, and safety plug. The catheter is inserted through the stoma and into the urinary bladder and is secured by the internal retention balloon. The device is offered in various sizes to accommodate different stoma diameters and lengths. On the shaft near the end is located a balloon which, when properly inflated, acts as an internal stabilizer preventing outward displacement through the stoma in the abdominal wall. The balloon is inflated through a separate inflation valve located in the external portion of the device.
The external profile of the device acts as a stabilizer to prevent inward migration and affords the user the ability to connect a provided Drainage Set.
The Drainage Set is identical in material and manufacturing process to certain configurations of the Irrigation Set included with the AMT Bowel Management Device previously cleared in K180026. The right-angle connector of the Drainage Set is compatible with the interlock on the LPSPC and is used to direct fluids drained from the bladder, through the catheter, and into a separate urinary collection bag.
The AMT Low-Profile Suprapubic Catheter & Drainage Set may optionally be marketed with a Foley Insertion Tray accessory. If included, the accessory would be a legally marketed Foley Insertion Tray, such as:
- AMSure Foley Insertion Tray (previously cleared Class II, Product Code FCM, K030664)
- Bardia Foley Insertion Tray (registered Class II, Product Code OHR, 510(k) exempt)
- Dynarex Foley insertion Tray without Catheter (registered Class II, Product Code OHR, 510(k) exempt)
The device is sold as sterile and can be initially placed in an outpatient-setting by a health care professional. The device may be replaced in an outpatient-setting or home setting by a health care professional or care giver.
The provided text describes a 510(k) premarket notification for the "AMT Low-Profile Suprapubic Catheter & Drainage Set." This document focuses on demonstrating substantial equivalence to predicate devices, rather than presenting a standalone study with specific acceptance criteria and performance metrics in the format requested.
Therefore, much of the requested information cannot be extracted directly from this document. The document primarily describes the types of testing performed and concludes that the device met acceptance criteria, but generally does not specify these criteria or report quantitative performance results against them.
Here's an attempt to answer the questions based on the available information:
1. A table of acceptance criteria and the reported device performance
The document states that the device "met or exceeded all the acceptance criteria and does not raise new questions of safety or effectiveness when compared to the predicate/reference devices." However, specific numerical acceptance criteria and precise performance data are not detailed in this summary. The performance is generally stated as meeting standards.
Acceptance Criteria Category | Reported Device Performance |

Clinical Performance (based on literature review) | Determined to function clinically as intended and benefits outweigh risks in the target user population. Risks (hematuria, wound infection, UTI, leakage, poor fit, discomfort, bladder spasms) are similar to those seen with this device type. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size:
- Bench Testing: Not specified. The document lists the types of tests but not numbers of samples.
- Clinical Performance (Literature Review): Clinical experience was reported on 34 adults and 188 pediatric patients across 22 published articles.
- Data Provenance: The clinical data is from a systematic literature review (retrospective). The countries of origin are not specified, only that the literature from "independent organizations" was reviewed.
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)
Not applicable. This was a systematic literature review, not a study where experts established ground truth for newly collected patient data. The "ground truth" for the clinical performance was derived from the findings reported in the published literature.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. The clinical evidence was gathered through a systematic literature review. The "reporting of this systematic review was guided by the standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement, as well as the Cochrane Handbook for Systematic Reviews of Interventions. Assessment of the included literature was completed using the critical appraisal tools published by the Joanna Brigges Institute." This describes the methodology for reviewing existing literature, not an adjudication process for a new test set.
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
Not applicable. This device is a suprapubic catheter, not an AI-assisted diagnostic or therapeutic device. The submission does not mention any AI components or MRMC studies.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a physical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the clinical performance aspects, the "ground truth" was derived from "clinical experience... reported on 34 adults and 188 pediatric patients" across published literature, guidelines from organizations like the Pediatric Urologists of Canada and the Canadian Urological Association, operative textbooks, and information from the International Continence Society (ICS). This can be broadly categorized as published clinical outcomes data and expert-derived guidelines/clinical experience.
8. The sample size for the training set
Not applicable. This is a physical medical device submission, not a machine learning model. There is no concept of a "training set" in this context.
9. How the ground truth for the training set was established

The One-Step Suprapubic Introducer is comprised of a stainless steel trocar stylet needle and a dilator with a peel-away sheath. The trocar stylet needle is 20 centimeters (cm) long with a trocar beveled tip at the distal end of the device. The dilator is 14-22 French (Fr) and 18-19 cm in length. The peel-away sheath is 14-22 Fr and 17 cm in length. The three components are designed to fit together to form a single assembly.
This document describes the Cook Incorporated One-Step Suprapubic Introducer (K182709) and its claim of substantial equivalence to a predicate device. The information provided focuses on the device's technical specifications and the performance tests conducted, rather than a clinical study involving human patients or AI systems. Therefore, many of the requested categories related to clinical studies, AI performance, and human reader effect sizes cannot be populated from the provided text.
Here's the breakdown of the information available:
1. A table of acceptance criteria and the reported device performance
The document broadly states, "All predetermined acceptance criteria were met" for all listed tests. Specific quantitative acceptance criteria are not provided.
Acceptance Criteria (Quantitative/Qualitative) | Reported Device Performance |
---|---|
Specific criteria not detailed in document | All predetermined acceptance criteria were met. |
For Biocompatibility: | |
- Cytotoxicity | Conforms to biocompatibility requirements |
- Sensitization | Conforms to biocompatibility requirements |
- Irritation/Intracutaneous Reactivity | Conforms to biocompatibility requirements |
- Acute Systemic Toxicity | Conforms to biocompatibility requirements |

The O'Brien Suprapubic Peel-Away Access Set is used for introducing a drainage catheter suprapubically into the bladder.
The Cook® SP Tube Introducer Set is used for introducing a drainage catheter suprapubically into the bladder.
The O'Brien Suprapubic Peel-Away Access Set includes a peel-away sheath, dilator, trocar needle and wire guide. The peel-away sheath is available in even-numbered French sizes ranging from 16.0 to 20.0 and measures 22 centimeters in length. Dual knobs allow the sheath, manufactured from thick wall radiopaque polytetrafluoroethylene material, to be peeled back and removed.
The Cook SP Tube Introducer Set is comprised of a 20 Fr sheath which is 15 cm in length, an introducer that fits within this sheath, two dilators, a wire guide and needle.
This document is a 510(k) Premarket Notification for the O'Brien Suprapubic Peel-Away Access Set and the Cook® SP Tube Introducer Set. It does not describe an AI/ML device or its performance characteristics.
Therefore, I cannot provide details on the acceptance criteria and study proving device meets acceptance criteria as typically requested for AI/ML medical devices. The document concerns traditional medical devices (catheter introducer sets) and focuses on demonstrating substantial equivalence to a predicate device through engineering and biocompatibility testing, not clinical performance metrics of an AI algorithm.
The document states:
- Performance Data: "The subject devices... were subjected to applicable testing to assure reliable design and performance under the testing parameters. The following tests have been conducted... Radiopacity Testing, Peel-Away Shaft Tensile Test, Dilator Shaft Tensile Test, Peel Force, Rollback Testing, Dilator Hub-to-Shaft Tensile Test, Compatibility Testing, Biocompatibility Cytotoxicity, Sensitization, Irritation/Intracutaneous Reactivity, and Acute Systemic Toxicity, Sterilization, Package integrity and stability, Shelf-life. All predetermined acceptance criteria were met."
However, it does not provide the specific acceptance criteria or the detailed results of these tests. It only states that they were met, which is common in a 510(k) summary where full test reports are not typically included.
The information you requested (sample sizes for test/training sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, ground truth types, etc.) are all relevant for AI/ML device evaluations and are not applicable or present in this submission for conventional medical devices.

They are available in two (2) tip styles, closed and open tip, The introducer kit includes a number of components including: Scalpel, Syringe, 18 gauge needle, Dilator and Peelable sheath, and Guidewire
This is a 510(k) summary for a medical device and does not contain information about a clinical study with detailed acceptance criteria and performance metrics in the way you've requested for an AI/ML device.
Here's an explanation of why the requested information cannot be fully provided based on the provided text, and what can be extracted:
- Device: Suprapubic Catheter and Introducer Set
- Submission Type: 510(k) Premarket Notification. This type of submission primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving novel efficacy or performance through extensive clinical trials as might be required for a PMA or for an AI/ML device.
Analysis of the Provided Text (and why it doesn't fit the AI/ML study request)
The document describes a conventional medical device (catheter and introducer set) and its comparison to predicate devices, focusing on demonstrating substantial equivalence based on:
- Indications for Use: Identical or similar to predicates.
- Technology and Construction: Identical or substantially equivalent materials, design, manufacturing, shape, and sizes, with the catheter often being an OEM product from a predicate manufacturer.
- Environments of Use: Identical to predicates.
- Patient Population: Identical to predicates.
- Indwelling Time: Identical to predicates.
- Convenience Kit: Comparison of kit components.
- Non-Clinical Testing Summary: This is the only area where "testing" is mentioned, but it's for physical performance of the device components (balloon burst, volume maintenance, deflation, guidewire fracture, flexion, tensile strength, corrosion) against established standards (ASTM F623, ISO 11070). This is not a study assessing diagnostic accuracy or clinical outcomes in humans, nor does it involve AI/ML.
- Materials: Biocompatibility testing per ISO 10993-1 and G95-1.
Therefore, many of your specific requests are not applicable to this 510(k) submission:
- A table of acceptance criteria and the reported device performance: The "performance" reported here is adherence to physical/material standards, not diagnostic accuracy. The acceptance criteria are "met the performance requirements of the standards" (ASTM F623, ISO 11070).
- Sample size used for the test set and the data provenance: Not applicable. There's no "test set" of patient data for an algorithm. The testing is material/device-specific.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No "ground truth" establishment in a clinical sense.
- Adjudication method: Not applicable.
- MRMC comparative effectiveness study: Not applicable. This is not an AI-assisted device.
- Standalone (algorithm only) performance: Not applicable. There's no algorithm.
- Type of ground truth used: Not applicable.
- Sample size for the training set: Not applicable. No training set for an algorithm.
- How the ground truth for the training set was established: Not applicable.
What can be extracted (re-interpreting "acceptance criteria" for a 510(k) of a conventional device):
For a 510(k) submission like this, "acceptance criteria" are generally framed as demonstrating substantial equivalence to predicate devices and meeting relevant recognized standards for the device's physical and material properties.
1. Table of Acceptance Criteria and Reported Device Performance (Non-Clinical/Material Focus)
Acceptance Criteria (Demonstrates Equivalence / Meets Standards) | Reported Device Performance |

The Swan Valley Medical Transurethral Suprapubic endo-Cystostomy (T-SPeC®) Surgical System is intended for suprapubic bladder catheterization (cystostomy) and drainage. The catheter should not be allowed to remain indwelling for more than 29 days.
The T-SPeCTM Surgical System is, in effect, a sterile suprapubic catheter and accessory kit consisting of a) a suprapubic catheter; b) a catheter punch instrument used to create a cystostomy and place the suprapubic catheter; and c) a piston syringe to fill the catheter balloon after placement.
Here's an analysis of the provided text regarding the acceptance criteria and supporting study for the Swan Valley Medical Transurethral Suprapubic endo-Cystostomy (T-SPeC™) Surgical System:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria Category | Acceptance Criteria | Reported Device Performance |
---|---|---|
Primary Basis for Substantial Equivalence | To demonstrate that T-SPeC™ Surgical System is as safe and effective as legally marketed predicates. | The submission claims the device is "substantially equivalent" to predicate devices, asserting that its modified technological characteristics "do not adversely affect the safety and effectiveness of the subject device" based on non-clinical bench studies. |
Suprapubic Catheter Design & Performance | No specific quantitative acceptance criteria are provided in the summary. Implies qualitative comparison to predicates for design and performance. | "various bench performance studies have been performed related to: • Suprapubic Catheter design and performance." (No specific results or parameters are presented in the summary.) |
Catheter Accessory Design & Performance | No specific quantitative acceptance criteria are provided in the summary. Implies qualitative comparison to predicates for design and performance. | "various bench performance studies have been performed related to: • Catheter accessory design and performance." (No specific results or parameters are presented in the summary.) |
Biocompatibility | To ensure the device materials are safe for human contact. | "various bench performance studies have been performed related to: • Biocompatibility." (No specific results, tests, or standards are presented in the summary.) |
Sterilization Validation & Shelf Life | To ensure the device is sterile and maintains its integrity over its intended shelf life. | "various bench performance studies have been performed related to: • Sterilization Validation & Shelf Life." (No specific results or parameters are presented in the summary.) |
A critical point to note is the absence of specific, quantitative acceptance criteria and their corresponding reported performance values within this 510(k) summary. The summary states that "various bench performance studies have been performed" but does not detail the specific criteria or the results of those studies. The primary "acceptance criterion" articulated is the demonstration of "substantial equivalence" to predicate devices based on non-clinical data.
2. Sample Size Used for the Test Set and Data Provenance
The provided 510(k) summary does not mention a "test set" in the context of clinical or performance data for an AI/algorithm-based device.
- Sample Size for Test Set: Not applicable as no clinical or AI-specific performance testing is detailed.
- Data Provenance: Not applicable. The submission explicitly states, "No clinical performance testing was performed." The equivalence is based on non-clinical bench studies.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
- Number of Experts: Not applicable. As no clinical performance testing or "test set" requiring expert ground truth was conducted, no experts were used for this purpose.
- Qualifications of Experts: Not applicable.
4. Adjudication Method for the Test Set
- Adjudication Method: Not applicable. Since no clinical performance testing requiring a "test set" with expert review was conducted, no adjudication method was used.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, Effect Size of Human Readers Improve with AI vs. Without AI Assistance
- MRMC Study: No. The provided text does not mention any MRMC comparative effectiveness study. This is not an AI/software as a medical device (SaMD) submission where such studies would be typical.
- Effect Size: Not applicable.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Standalone Performance: No. The device is a "Surgical System" consisting of physical medical instruments (catheter, punch instrument, syringe), not a standalone algorithm or software. Therefore, the concept of "algorithm only" performance is not relevant to this submission.
7. The Type of Ground Truth Used
- Type of Ground Truth: Not applicable in the context of clinical or AI performance. The "ground truth" for this device's safety and effectiveness relies on established engineering principles, material science, and performance testing benchmarks for similar physical medical devices (e.g., integrity of materials, sterility, functionality of mechanical components). The "ground truth" is essentially conformance to design specifications and recognized standards for physical medical devices, as demonstrated by bench testing.
8. The Sample Size for the Training Set
- Sample Size for Training Set: Not applicable. This is a submission for a physical medical device, not an AI/machine learning model. There is no concept of a "training set" in this context.
9. How the Ground Truth for the Training Set Was Established
- How Ground Truth for Training Set Was Established: Not applicable, as there is no training set for a physical device.
Summary of the Study:
The study proving the device meets its "acceptance criteria" (which in this case is primarily substantial equivalence to predicate devices for safety and effectiveness) consists of non-clinical bench performance studies.
The 510(k) summary explicitly states: "No clinical performance testing was performed. Substantial equivalence for the subject device is based on the aforementioned non-clinical bench studies."
These bench studies covered:
- Suprapubic Catheter design and performance.
- Catheter accessory design and performance.
- Biocompatibility.
- Sterilization Validation & Shelf Life.
The detailed results and specific acceptance parameters of these bench studies are not provided in the 510(k) summary (which is common for these summaries). The FDA's decision to clear the device implies that the non-clinical data was sufficient to demonstrate substantial equivalence to legally marketed predicate devices for the stated intended use.

- Non-deflator test
- Reported Finding: "Testing showed equivalence between the proposed catheter and commercially available suprapubic catheters." Again, this is a statement of equivalence rather than a specific performance metric against a pre-defined acceptance criterion. The acceptance criteria for these tests would be internal specifications (e.g., "flow rate must be within X% of predicate," "balloon burst volume must be Y mL ± Z%"), but these are not disclosed in the 510(k) summary.
In summary, for a 510(k) submission like this, the focus is on demonstrating that the new device is "substantially equivalent" to an already legally marketed predicate device, primarily through non-clinical testing and comparison of design, materials, and intended use. It does not typically involve the type of clinical performance studies with acceptance criteria, ground truth, and expert adjudication that would be found in a PMA or a submission for a novel, high-risk device.

The kit is used for percutaneous bladder drainage and to drain fluids to and from the urinary tract.
The kit consists of two major components: silicone catheter and plastic introducer assembly, along with attachment tape to fix the catheter to the skin, if required, and an optional scalpel. The kit is used for percutaneous bladder drainage. There are two types of silicone catheters. The first comes equip with one pair of drainage eyes. The second type of silicone catheter comes with six drainage eves arranged in a pigtail shape.
This document is a 510(k) Summary for a medical device (Rusch Suprapubic Tray). It describes the device, its intended use, and claims substantial equivalence to legally marketed predicate devices.
This document does not contain information regarding acceptance criteria, device performance, study details (like sample size, data provenance, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance).
Therefore, I cannot fulfill your request for a table of acceptance criteria and reported device performance or other study-related details based on the provided text. The document focuses on regulatory submission for substantial equivalence rather than a detailed performance study.
