The Tamarin Blue PTCA RX Dilatation Catheters are indicated for balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis, for the purpose of improving myocardial perfusion.
Device Story
The Tamarin Blue PTCA RX Dilatation Catheter is a rapid exchange (RX) balloon catheter used by physicians in clinical settings for coronary angioplasty. It features a single proximal lumen, dual distal lumen, semi-compliant inflatable balloon, and a soft tapered distal tip. The device is inserted over a 0.014" guidewire; a luer lock hub connects to an external inflation device. Two radiopaque markers facilitate balloon positioning across the stenosis. A hydrophilic coating on the distal portion improves catheter pushability. By inflating the balloon to a known diameter at specific pressures, the device dilates stenotic lesions, thereby improving myocardial perfusion. The device is supplied sterile for single-use.
Clinical Evidence
Bench testing only. Testing included coating inspection and integrity, balloon preparation, deployment, retraction, rated burst, fatigue, compliance, inflation/deflation, and particulate testing. Biocompatibility was verified via comparison to predicate and reference devices.
Indicated for balloon dilatation of stenotic coronary arteries or bypass grafts to improve myocardial perfusion in patients requiring percutaneous transluminal coronary angioplasty.
Regulatory Classification
Identification
Standard PTCA Catheter: 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. Cutting/scoring PTCA Catheter: 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.

### INTENDED USE/INDICATIONS FOR USE:
The Tamarin Blue PTCA RX Dilatation Catheters are indicated for balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis, for the purpose of improving myocardial perfusion.
### DEVICE DESCRIPTION:
The Tamarin Blue PTCA RX Dilatation Catheter is a standard Rapid Exchange (RX) PTCA catheter with a single lumen proximally, a dual lumen distally, a semi-compliant inflatable balloon and a soft, tapered distal tip to aid in crossing tight stenoses. One lumen of the catheter's dual lumen is used for inflation and deflation of the balloon, and the other lumen allows guide wire access through the distal part of the catheter. The maximum recommended guide wire diameter is 0.014". A luer lock fitting (hub) allows connection with an inflation device. Two radiopaque markers on the guide wire lumen tubing provide visual reference points for balloon positioning across the stenosis. A hydrophilic coating has been applied on the distal portion of catheter i.e., up to the RX port, to improve catheter pushability. The balloon material expands to a known diameter at a specific pressure as defined in the compliance table supplied with the catheter.
The device is supplied sterile and intended for one-time use.

### COMPARISON WITH PREDICATE DEVICE:
Comparisons of the Tamarin Blue PTCA RX Dilatation Catheter and the predicate device shows that the technological characteristics of the subject device such as components, design, sterilization method, shelf life and operating principle are identical to the currently marketed predicate device. Comparison of the subject device to the reference device show that the material, specifically the hydrophilic coating, are identical. Therefore, the addition of a hydrophilic coating to the subject device does not raise any new questions of safety or effectiveness.
The intended use/indications for use between the subject device and the predicate device are identical.

- Coating Inspection
- Coating Integrity (Performance and Durability)
- Balloon preparation, deployment and retraction
- Balloon Rated Burst
- Balloon Fatigue ●
- Balloon compliance
- Balloon inflation/deflation
- Particulate ●
In vitro bench testing demonstrated that the hydrophilic coating performed as intended and did not impact the functionality of the device.
### BIOCOMPATIBILITY:
The Tamarin Blue PTCA RX Dilatation Catheter was compared to the predicate and reference devices, Based on similarities of the materials used in the subject device to its predicates / reference devices, the biocompatibility of the Tamarin Blue PTCA RX Dilatation Catheter was verified to be the same as those of the predicates / reference devices.
The results are being leveraged due to the similarities in the underlying materials to which the hydrophilic coating is applied.
The results of the testing show that the subject device in this submission met all acceptance criteria and the subject device is biocompatible.
### CONCLUSION:
The Tamarin Blue PTCA RX Dilatation Catheter included in this notification is identical to the previously cleared predicate device in terms of intended use and technological characteristics. Any differences that exist between the Tamarin Blue PTCA RX Dilatation Catheter and the predicate did not raise any new questions of safety or effectiveness,
The Tamarin Blue PTCA RX Dilatation Catheter is substantially equivalent to the reference product cleared in the US in terms of biocompatibility.
