Abstract
Official abstract text for this publication.
Medical devices and methods of fabricating such medical devices, such as stents, formed at least in part from a metal matrix composite including bioceramic particles dispersed within an erodible metal are disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A stent comprising a stent body consisting of a metal matrix composite, the composite including biodegradable bioceramic nanoparticles dispersed within and throughout a bioerodible metal matrix, wherein the bioceramic nanoparticles are spherical and have a diameter from 1 nm to 100 nm, wherein the biodegradable bioceramic nanoparticles that are dispersed modify the erosion rate of the stent body in a vascular environment and enhance mechanical properties of…
