title: Heparin-releasing intravascular guidewires.
abstract: The distal part of a percutaneous translumenal coronary angioplasty (PTCA) guidewire should not only be flexible, nonkinking, radiopaque and lubricious, but also nonthrombogenic. Possible formation of thrombotic emboli at a guidewire's surface enhances the risk for occlusion at the coronary lesion downstream. This article reports on the development of a new PTCA guidewire that releases heparin from the lubricious hydrophilic coating on its distal part.
