Abstract
A drug storing and metering stent for placement within a vessel comprising an outer member having a lumen, an inner member positioned within the lumen of the outer member. A space separates the inner member from the outer member and within which space a therapeutic drug is disposed. The stent includes at least one protrusion provided on at least one of the inner and outer members and extending across the space so as to cause a friction fit between the inner and outer members. The stent also includes a pattern of perforation across both the inner and outer members to permit the stent to expand radially. The invention also relates to a method of making such a stent, and a method of releasing a therapeutic drug within a vessel.
