The Reprocessed 3D Diagnostic Ultrasound Catheters are indicated for intra-cardiac and intra-luminal visualization of cardiac and great vessel anatomy and physiology as well as visualization of other devices in the heart. The 3D Diagnostic Ultrasound Catheter provides location information when used with the CARTO® XP EP Navigation System Version 9 or greater.
SterilMed Reprocessed 3D Diagnostic Ultrasound Catheters are specially designed catheters that provide two-dimensional imaging using an ultrasound transducer and three-dimensional location information using a location sensor. The ultrasound transducer and location sensor are at the distal tip of the catheter and can be positioned for ultrasound imaging and 3D mapping by a steering mechanism that rotates the catheter tip and provides variable deflection. 3D Diagnostic Ultrasound Catheters incorporate a hand piece, a flexible shaft and a distal tip section containing an ultrasound transducer and a location sensor. The ultrasound transducer of this device has an acoustic array that is identical to the AcuNav™ 10F Diagnostic Ultrasound Catheter. The 3D Diagnostic Ultrasound Catheter's 3D location sensor provides location information to the CARTO® XP EP Navigation System (mapping system). The 3D Diagnostic Ultrasound Catheters is 10 French with a 90 cm insertion length.
Note: Only the catheter is the subject of this submission; accessories and/or any other related equipment are not included in the scope of this submission.
The provided text describes the 510(k) summary for Reprocessed 3D Diagnostic Ultrasound Catheters. This document details the substantial equivalence to predicate devices and outlines functional and safety testing. However, it does not contain the specific information requested in the prompt regarding acceptance criteria and a study proving device performance in the context of AI/algorithm performance.
Here's a breakdown of why the requested information cannot be fully extracted and what can be inferred:
Why the requested information cannot be fully extracted:
- No AI/Algorithm Component: The document describes a reprocessed physical medical device (ultrasound catheters). It does not mention any artificial intelligence (AI) component, algorithm, or software that performs diagnostic analysis. The "3D location sensor" provides data to a "mapping system" (CARTO® XP EP Navigation System), but the catheter itself is the device being described, not an AI interpreting the data from it.
- Focus on Reprocessing and Substantial Equivalence: The primary purpose of this 510(k) submission is to demonstrate that the reprocessed catheters are as safe and effective as their original, new counterparts and existing predicate devices. The "studies" mentioned are focused on the safety and functionality of the reprocessed hardware (cleaning validation, sterilization, biocompatibility, mechanical reliability, electrical safety), not on the diagnostic performance of an AI model.
- Lack of Performance Metrics for AI: Consequently, there are no acceptance criteria related to sensitivity, specificity, AUC, etc., for an AI model. There's no test set, training set, or ground truth establishment relevant to AI performance.
Based on the provided text, here's what can be answered or inferred about the device and its testing, excluding AI-specific details:
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a physical reprocessed device and not an AI or diagnostic algorithm in the sense implied by the prompt, the "acceptance criteria" and "performance" relate to the physical and functional integrity after reprocessing, as well as its equivalence to predicate devices.

| Ethylene Oxide Residuals | Measuring residual levels of ethylene oxide (if applicable) (ISO 10993-7). | Ethylene oxide residual testing (ISO 10993-7) was performed. Specific results not detailed, but implied successful testing. |
| Cleaning Residuals | Testing for residues left after the cleaning process. | Cleaning residuals testing was performed. Specific results not detailed, but implied successful testing. |
| Packaging Validation | Ensuring package integrity and sterility maintenance (ASTM D4169, ASTM F88, ASTM F2096). | Packaging validation (ASTM D4169, ASTM F88, ASTM F2096) was performed. Specific results not detailed, but implied successful validation. |
| Shelf Life Validation | Determining the period the device maintains its function and sterility. | Shelf life validation (ASTM 1980-99) was performed. Specific results not detailed, but implied successful validation. |
| Functional Performance | Verifying the proper operation of the ultrasound and 3D location sensor components. Includes aspects like ultrasound acoustic array identical to AcuNav™ 10F, and location information compatibility with CARTO® XP EP Navigation System. | Functional performance (including both the ultrasound and 3D location sensor components) was validated using bench and laboratory testing. The device is said to have an "acoustic array that is identical to the AcuNav™ 10F Diagnostic Ultrasound Catheter" and provides "location information to the CARTO® XP EP Navigation System Version 9 or greater." Implied successful performance matching predicate. |
| Mechanical Reliability | Assessing the physical durability and integrity of the catheter (e.g., steering mechanism, shaft flexibility). | Mechanical reliability was validated using bench and laboratory testing. Specific results not detailed, but implied successful validation. |
| Electrical Safety (Hipot) | Ensuring electrical insulation integrity (IEC 60601-1:2005, Clause 8.8.3). | Hipot testing (IEC 60601-1:2005, Clause 8.8.3) was performed. Specific results not detailed, but implied successful testing. |
| Electrical Safety (Defib) | Ensuring resistance to defibrillator discharge (IEC 60601-1:2005, Clause 8.5.5.1). | Defibrillation testing (IEC 60601-1:2005, Clause 8.5.5.1) was performed. Specific results not detailed, but implied successful testing. |

SOUNDSTAR™ 3D Diagnostic Ultrasound Catheter and AcuNav™ Diagnostic Ultrasound Catheter based on functional design, materials, indications for use, and methods of construction. |
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 (Test Set): Not specified in terms of a "test set" for diagnostic performance, as it's not an AI/algorithm. However, representative samples of the reprocessed catheters were used for functional and safety testing. The exact number of units tested for each specific test is not provided in this summary.
- Data Provenance: Not applicable in the context of diagnostic data. The tests were performed in a laboratory/bench setting, likely in the US (where SterilMed, Inc. is located).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not Applicable: This criterion relates to diagnostic algorithms/AI. For a reprocessed physical device, "ground truth" refers to established engineering standards, material properties, and biological safety standards (e.g., ISO, ASTM, USP). The "experts" would be testing engineers, microbiologists, quality control personnel, etc., ensuring the device meets these pre-defined specifications. The document does not detail the number or specific qualifications of these personnel.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
- Not Applicable: Adjudication methods are typically used for establishing consensus ground truth in diagnostic studies. For engineering and safety tests, the results are typically objectively measured against established pass/fail criteria or reference standards.
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: This is related to diagnostic algorithms/AI. This document describes a physical medical device.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- No: This is related to diagnostic algorithms/AI. This document describes a physical medical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Engineering and Safety Standards: The "ground truth" for the reprocessed catheter's performance is adherence to established international and national standards for medical device safety and functionality (e.g., ISO 11135, USP , ISO 10993-1 and -7, ASTM D4169, ASTM F88, ASTM F2096, ASTM 1980-99, IEC 60601-1:2005, IEC 60601-2-27), and demonstrating equivalence to the original predicate devices' performance characteristics.
8. The sample size for the training set
- Not Applicable: There is no "training set" as this is not an AI/algorithm.
9. How the ground truth for the training set was established
- Not Applicable: There is no "training set."
