The Mozec - Rx PTCA Balloon Dilatation Catheter is indicated for balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion. The Mozec - Rx PTCA Balloon Dilatation Catheter (balloon models 2.25mm) is also indicated for post delivery expansion of balloon expandable stents.
The Mozec NC – Rx PTCA Balloon Dilatation Catheter is indicated for balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion. The Mozec NC - Rx PTCA Balloon Dilatation Catheter is also indicated for post delivery expansion of balloon expandable stents.
Mozec - Rx PTCA Balloon Dilatation Catheter is a sterile, single use rapid exchange catheter consisting of a semi-compliant balloon, a soft tip, a dual lumen distal shaft and a single lumen proximal shaft. Radiopaque platinum/iridium marker(s) contained in the balloon segment facilitate fluoroscopic visualization of the proximal and distal ends of the Mozec balloon's working length (2.00 mm to 4.50 mm sizes) or the centre of the balloon's working length (1.50 mm size). The Mozec balloons are offered in diameters ranging from 1.50 mm to 4.50 mm and lengths varying from 9 mm to 41 mm.
Mozec NC - Rx PTCA Balloon Dilatation Catheter is a sterile, single use rapid exchange catheter consisting of a non-compliant balloon, a soft tip, a dual lumen distal shaft and a single lumen proximal shaft. Radiopaque platinum/iridium marker(s) contained in the balloon segment facilitate fluoroscopic visualization of the proximal and distal ends of the Mozec NC balloon's working length. The Mozec NC balloons are offered in diameters ranging from 2.00 mm to 4.50 mm and lengths varying from 8 mm to 38 mm.
The provided document is a 510(k) premarket notification for PTCA (Percutaneous Transluminal Coronary Angioplasty) Balloon Dilatation Catheters. It describes the device, its intended use, and non-clinical performance data to demonstrate substantial equivalence to previously cleared predicate devices.
However, the document does not contain information related to an AI/ML medical device, nor does it discuss acceptance criteria and studies proving the device meets those criteria in the context of AI/ML performance. Instead, it refers to standard engineering and performance tests for medical devices like balloon catheters.
Therefore, I cannot extract the requested information regarding acceptance criteria and studies for an AI/ML device from this text. The questions posed in your prompt (e.g., sample size for test set/training set, number of experts for ground truth, MRMC study, standalone performance) are specific to the validation of AI/ML algorithms, which is not the subject of this document.
§ 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.
