    摘要: The invention is directed to an implantable stent prosthesis comprising a sidewall and at least one channel for containing a biologically active material. A method for making such stent prosthesis is also disclosed. In the method, at least one tube or mandrel is placed in contact with a covering material on a stent and surrounded by the covering material to form a channel. Alternatively, a channel can be formed by covering the tube or mandrel with a channel material and exposing the covered tube or mandrel to an appropriate treatment. The channel can be attached to a sidewall of a stent or attached to a strut material to form a stent wire. A method of treating an afflicted area of a body lumen by implanting the stent prosthesis is also disclosed.

    摘要: An intraluminal medical device having a flowpath therethrough, the device including a plurality of substantially cylindrical serpentine shaped segments which define a generally tubular body, each serpentine segment having a plurality of struts interconnected by alternating end portions, segments which are adjacent one another connected one to the other. The medical device has a pre-crimped diameter and crimped diameter and is constructed and arranged such that as the cylindrical shaped segments are crimped from the pre-crimped diameter to the crimped diameter at least some of the end portions project into the flowpath.
