| 摘要 |
<p>The present invention is directed to a medical device, specifically a prosthesis which utilizes a novel class of blends between biodegradable polymers and bioceramics for medical device applications allowing one to capitalize on the biodegradable nature of these two distinct materials while enhancing the strength of these devices through the addition of various amounts of bioactive ceramic and glasses to biodegradable polymers. The blend may be fabricated into a medical device such as a stent or a distal protection device, and may incorporate various agents to enhance radioapacity and/or pharmacological function. In addition, the blend may be used as a coating to a medical device. In one embodiment a method to fabricate a stent or distal protection device comprises the steps of:
blending a biodegradable polymer solution with bioactive ceramic particles to create a material; and either
forming said material into a desired shape for a stent or a distal protection device application; or
applying said material as a coating material to encapsulate a stent or distal protection device.</p> |
