摘要： An implantable medical device, such as a stent or graft, having asperities on a designated region of its outer surface is disclosed. The asperities can serve to improve retention of one or more layers of a coating on the device and to increase the amount of coating that can be carried by the device. The asperities can be formed by using a stream of pressurized grit to roughen the surface. The asperities can also be formed by removing material from the outer surface, for example, by chemical etching with or without a patterned mask. Alternatively, the asperities can be formed by adding material to the outer surface, for example, by welding powder particles to the outer surface or sputtering.

摘要： A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold also has a reduced crimped profile and a modification of the scaffold's ring structure at the crowns that contributes to the reduced crimped profile.

摘要： A hybrid stent is formed which exhibits both high flexibility and high radial strength. The expandable hybrid stent for implantation in a body lumen, such as a coronary artery, consists of radially expandable cylindrical rings generally aligned on a common longitudinal axis and interconnected by one or more links. In one embodiment, a dip-coated covered stent is formed by encapsulating cylindrical rings within a polymer material. In other embodiments, at least some of the rings and links are formed of a polymer material which provides longitudinal and flexural flexibility to the stent. These polymer rings and links are alternated with metallic rings and links in various configurations to attain sufficient column strength along with the requisite flexibility in holding open the target site within the body lumen. Alternatively, a laminated, linkless hybrid stent is formed by encapsulating cylindrical rings within a polymer tube.
