The Chocolate™ XD PTCA Balloon Dilatation Catheter is indicated for balloon dilatation of the stenotic portion of coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion including in-stent restenosis.
The Chocolate XD PTCA Balloon Catheter is a Rapid Exchange (RX) angioplasty balloon catheter. It consists of a stainless steel hypotube and a nylon shaft, a semi compliant balloon at the distal end of the catheter with a metal constraining structure (CS) and an atraumatic distal tip. Upon inflation, the CS expands with the balloon to a certain diameter; the balloon continues the expansion beyond the CS. Upon deflation, the CS returns to its original shape, and is removed from the vessel along with the balloon catheter. Two Radiopaque markers define the working length of the Chocolate Balloon. The proximal end of the catheter is comprised of a hub used to inflate the balloon that can be connected to a standard inflation device. The catheter will be 140 ±5cm in length, compatible with 0.014" guidewire.
The provided document is a 510(k) summary for the TriReme Medical Chocolate XD PTCA Balloon Catheter. This document does not contain information on the acceptance criteria, study design, or results for an AI/ML powered device. It describes a medical device, a balloon catheter, and its equivalence to a predicate device, based on standard performance testing for devices of this type, not for an AI/ML algorithm.
Therefore, I cannot provide the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, expert qualifications, adjudication methods, or MRMC studies for an AI/ML device from this document.
The document discusses standard device performance testing for a physical medical catheter, such as:
- Dimensional Verification
- Balloon Preparation, Deployment & Retraction
- Flexibility & Kink
- Balloon Rated Burst Pressure (RBP)
- Rate Burst Pressure in Stent
- Balloon Fatigue
- Balloon Fatigue in Stent
- Balloon Compliance
- Balloon Inflation and Deflation
- Catheter Bond Strength
- Tip Pull Test
- Torque Strength
- Radiopacity
- Particulate Evaluation
- Biocompatibility Testing
These are physical and material property tests to ensure the catheter functions safely and effectively, not diagnostic performance metrics for an AI system.
§ 870.5100 Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheter.
(a)
Standard PTCA Catheter —(1)Identification. A PTCA catheter is a device that operates on the principle of hydraulic pressurization applied through an inflatable balloon attached to the distal end. A PTCA balloon catheter has a single or double lumen shaft. The catheter features a balloon of appropriate compliance for the clinical application, constructed from a polymer. The balloon is designed to uniformly expand to a specified diameter and length at a specific pressure as labeled, with well characterized rates of inflation and deflation and a defined burst pressure. The device generally features a type of radiographic marker to facilitate fluoroscopic visualization of the balloon during use. A PTCA catheter is intended for balloon dilatation of a hemodynamically significant coronary artery or bypass graft stenosis in patients evidencing coronary ischemia for the purpose of improving myocardial perfusion. A PTCA catheter may also be intended for the treatment of acute myocardial infarction; treatment of in-stent restenosis (ISR) and/or post-deployment stent expansion.(2)
Classification. Class II (special controls). The special control for this device is “Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters.” See § 870.1(e) for the availability of this guidance document.(b)
Cutting/scoring PTCA Catheter —(1)Identification. A cutting/scoring PTCA catheter is a balloon-tipped catheter with cutting/scoring elements attached, which is used in those circumstances where a high pressure balloon resistant lesion is encountered. A cutting/scoring PTCA catheter is intended for the treatment of hemodynamically significant coronary artery stenosis for the purpose of improving myocardial perfusion. A cutting/scoring PTCA catheter may also be indicated for use in complex type C lesions or for the treatment of in-stent restenosis.(2)
Classification. Class III (premarket approval). As of May 28, 1976, an approval under section 515 of the act is required before this device may be commercially distributed. See § 870.3.
