Intended Use

The PW Guidewires are intended to facilitate placement of balloon dilatation catheters or other intravascular devices during percutaneous transluminal coronary angioplasty (PCTA) and percutaneous transluminal angioplasty (PTA). The PW Guidewires are not to be used in cerebral blood vessels.

Device Story

Steerable guidewire used to facilitate placement of balloon dilatation catheters or other intravascular devices in coronary and peripheral vasculature; excludes cerebral vessels. Device consists of stainless steel solid core wire, 0.014" diameter, 180cm length; features distal radiopaque coil, hydrophilic distal coating, and PTFE proximal coating.

Benefits include improved access to target lesion sites for angioplasty. No electronic or software components.

Clinical Evidence

Bench testing only. Testing included tensile strength, torque strength, torqueability, tip flexibility, tip load, coating adhesion, simulated use, resistance to wire fracture, dimensional verification, catheter compatibility, and radiopacity testing. Biocompatibility evaluated per ISO 10993-1. All tests met acceptance criteria.

Technological Characteristics

Stainless steel solid core wire; 0.014" (0.36mm) nominal diameter; 180cm length. Distal radiopaque coil; hydrophilic distal coating; PTFE proximal coating. Sterilized via Ethylene Oxide to SAL 10^-6. Mechanical device; no energy source or software.

Indications for Use
