Flexible, radially expansible luminal prostheses

摘要: The present invention provides methods and apparatus for deploying luminal prostheses, such as stents, grafts, or stent-grafts, to walls at a target site within an anatomical lumen. In one aspect of the invention, prostheses are designed negotiate curves, bends other irregularities in body passageways so facilitate deployment stents minimize injury walls. addition, have sufficient flexibility bend articulate substantially conform tortuous lumen site, which enhances post-deployment performance stent. another provided securing These provide effective frictional lock between stent wall inhibit migration and/or failure
