Here's a summary of the acceptance criteria and the study that proves the device meets them, based on the provided text:

Acceptance Criteria and Device Performance Study

The K122012 submission for the Z-MED and Z-MED II Catheters primarily relies on in-vitro (bench) testing and a review of existing clinical data for safety and effectiveness. No specific algorithms or human-in-the-loop performance studies are described as this is a medical device (catheter), not an AI/software device.

1. Table of Acceptance Criteria and Reported Device Performance

The provided text details in-vitro test results for the Z-MED and Z-MED II catheters, as well as two predicate devices (NuCLEUS-X and NuCLEUS). The table below focuses on the Z-MED and Z-MED II results as the subject devices.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size for In-Vitro Testing: The document does not explicitly state the numerical sample size for each in-vitro test (e.g., how many catheters were visually inspected or burst tested). It refers to "All catheters" or "All samples" meeting criteria, indicating that a sufficient number were tested.
• Data Provenance (Clinical):
  • Country of Origin: The clinical evaluation report was prepared to meet the requirements of the Medical Device Directive MOD 93/42/EEC (European Union standard). The clinical use of the Z-MED and Z-MED II catheters for BAV and BMV is mentioned in "those countries where they are used," and for BPV in "the United States."
  • Retrospective/Prospective: The clinical information gathered appears to be a retrospective review of existing clinical literature, device history, previous sales, and reported complaints. It references "Numerous clinical studies reported in literature" and "200 patients" without incidents from BAV prior to TAVI.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

This information is not applicable and not provided in the context of this submission. The tests described are in-vitro bench tests for a physical medical device (catheter), which do not typically involve experts establishing ground truth in the way it's done for diagnostic AI/software. The ground truth for in-vitro tests is based on objective physical measurements and engineering specifications.

For the clinical context, the "ground truth" refers to observations from actual patient use, as reported in clinical literature and through device monitoring. No specific number or qualification of experts reviewing patient outcomes is provided beyond the implicit understanding that medical professionals conducted the procedures and reported outcomes.

4. Adjudication Method for the Test Set

This is not applicable for the in-vitro bench testing described. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies or for establishing ground truth in cases where there's variability in interpretation (e.g., image analysis by multiple radiologists). The in-vitro tests are objective physical measurements.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

An MRMC study is not applicable and not mentioned. This type of study is relevant for diagnostic devices, especially those involving human interpretation of data, often comparing human performance with and without AI assistance. The Z-MED and Z-MED II are interventional catheters, not diagnostic devices or AI software. There's no AI component mentioned to compare human readers with or without.

6. Standalone (Algorithm Only) Performance Study

This is not applicable and not mentioned. The devices are physical catheters, not algorithms or software. Therefore, there is no standalone (algorithm only) performance to evaluate.

7. Type of Ground Truth Used

• In-Vitro Testing: The ground truth for the in-vitro tests is established by the predefined engineering specifications and acceptance criteria outlined in the table (e.g., balloon diameter within +/- 10% of labeled, no breaks, inflation/deflation times). These are objective, measurable physical parameters.
• Clinical Evaluation: The "ground truth" for clinical safety and performance is based on real-world patient outcomes and reported incidents/adverse events from existing clinical use and literature reviews.

8. Sample Size for the Training Set

This is not applicable. The Z-MED and Z-MED II are physical medical devices undergoing traditional bench testing and clinical review, not AI models that require training sets.

9. How the Ground Truth for the Training Set Was Established

This is not applicable, as there is no training set for a physical medical device.

The NuMED, Inc. PTS X™ Sizing Balloon catheter is a coaxial catheter for use in those patients with cardiovascular defects wherein accurate measurement of the defect is important to select the appropriately sized occluder device. The outer body is made of polymeric tubing, and the inner tubing is comprised of a multi layer extrusion of polyamide (Vestamid PA12) that surrounds a braid of 304 LV Stainless Steel. The catheter features a proximal end bifurcate with two distinct luminal passages. The inflation lumen terminates into a distally mounted balloon. This balloon is of the non-compliant variety and will have a typical single wall thickness of 0.0004". This balloon is designed to insert through the smallest possible introduction sleeve. The through lumen terminates at the tip of the catheter and will accept the passage of the appropriate guidewire. This lumen has radiopaque platinum marker bands under the balloon shoulders for placement using fluoroscopy. Additionally, there are two radiopaque platinum marker bands spaced at 10mm (as measured from leading edge to leading edge). These bands are located at the balloon center and are used as a distance reference. The catheter is white in color and the balloon material is clear. The catheter balloon diameter is stamped onto the Y sleeve and the balloon extension is labeled with balloon diameter x balloon length x introducer size x shaft size x usable length x guidewire size and the catheter lot number. The catheter is packaged in a polyethylene loop and is double packed in two heat sealed Tyvek pouches.

The provided text is a clearance letter from the FDA for the NuMED PTS X Sizing Balloon Catheter, not a study report. Therefore, it does not contain information about acceptance criteria, device performance, sample sizes, ground truth establishment, or multi-reader multi-case studies.

The document primarily states that the device is substantially equivalent to a legally marketed predicate device (NuMED PTS Catheter) based on its intended use and material similarity. It outlines the regulatory classification and general requirements for the device.

Here's a breakdown of why the requested information cannot be extracted from the provided text:

• No clinical study or performance data: The letter focuses on the regulatory clearance process and substantial equivalence, not on a detailed study proving performance against specific acceptance criteria.
• No mention of acceptance criteria: Specific metrics for device performance (e.g., accuracy of measurement, safety rates) that would constitute "acceptance criteria" are not listed.
• No device performance metrics: The document describes the device and its intended use but does not provide quantitative or qualitative data on how well it performs its function.
• No sample size for test set: No clinical or laboratory test results are detailed with sample sizes.
• No data provenance: Information on the origin of data (if any), such as geographical location or retrospective/prospective nature, is absent.
• No expert involvement: There is no mention of experts establishing ground truth or their qualifications.
• No adjudication method: This would be relevant to evaluating expert consensus, which isn't discussed.

This catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac, and renal arteries. These catheters are not designed to be used in the coronary arteries.

The Mullins X™ catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac and renal arteries. The catheter is a coaxial over the wire catheter with a balloon near the distal tip. One lumen permits guidewire insertion to facilitate advancement of the catheter, while the other lumen is for balloon inflation and deflation.

The balloons of the MULLINS X™ PTA Catheter are made of a non-compliant polymeric material. The two laminate balloon system is designed to inflate to a specific diameter at a given pressure. The change in diameter is minimal over the range of inflation pressures. The balloons are heat bonded to the shaft.

The outer body is made of polymeric tubing, and the inner tubing is comprised of a multi layer extrusion of polyamide (Vestamid PA12) that surrounds a braid of 304 LV Stainless Steel. The area under the balloon is enhanced with five radiopaque platinum image bands. Two that are 5mm on each side of the balloon center and two more under the balloon shoulders. An additional image band is imbedded into the tip of the catheter as an additional safety measure.

The catheter is white in color and the balloon material is clear. The catheter balloon diameter and name is stamped onto the Y sleeve and the balloon extension is labeled with balloon diameter x balloon length x introducer size x shaft size x usable length x guidewire size and the catheter lot number. The catheter is packaged in a polyethylene sheath and is double packed in two heat sealed Tyvek pouches.
