Medical device for delivering biologically active material
First Claim
1. An expandable stent comprising two ends and a tubular sidewall between the two ends, wherein the sidewall comprises a plurality of struts, and a plurality of projecting elements located proximate at least one stent end;
- wherein each projecting element comprises a first end and a second end;
wherein the first projecting element end is integral with or attached to a strut;
wherein the second projecting element end is capable of defining at least one stent end when the stent is in an expanded position; and
wherein at least one of the struts or at least one of the projecting elements comprises a biologically active material.

Abstract
This invention relates generally to a stent comprising a plurality of struts and a plurality of projecting elements integral with the struts. At least some of the struts and some of the projecting elements comprise a biologically active material. The struts are configured in a tubular shape or tubular sidewall having two ends. One end of at least one of the projecting elements defines an end of the stent when the stent is expanded. The invention is also directed to a method for delivering the biologically active material to body tissue of a patient by inserting such an expandable stent into body of the patient. The invention is further directed to a system comprising the expandable stent and a balloon catheter for expanding the stent.
