C22C 38/18

US Classification:

623 115, 75392

Abstract:

An implantable medical device includes a bioerodible portion adapted to erode when exposed to a physiological environment. The bioerodible portion includes an alloy comprising at least 10 weight percent chromium and has an outer surface having a ratio of chromium oxide to chromium metal of less than 5. The bioerodible implantable medical device can be created by implanting metallic ions into an alloy including at least 10 weight percent chromium to define an outer surface of a medical implant, or precursor thereof.

US Classification:

623 146, 427 224, 428457, 428461

Abstract:

An implantable metallic medical device having a dual-layered coating with a primer layer having functional groups capable of forming an organo-metallic complex with iron species and a second biocompatible polymer layer. The primer layer is baked onto the metallic medical device functioning as a tie layer between the surface of the medical device and a second biocompatible polymer layer disposed on the primer layer. Baking improves tie layer adhesion and in some cases provides an organo-metallic complex with the metal substrate. The second biocompatible polymer may can a therapeutic agent.

Abstract:

The present disclosure is directed to embodiments and methods of reducing or eliminating erosion resulting from the use of an occluder, as well as reducing or eliminating other interference with cardiac tissue by an occluder, including reducing pressure on cardiac tissue, minimizing micro-perforations, and/or minimizing residual leak by improving sealing around the occluder. In particular, the present disclosure is directed to providing an external skirt on an occluder that improves sealing of the occluder while reducing interference with the cardiac tissue by the occluder.
