Abstract
This invention is a medicament delivery vehicle, the vehicle comprising tubular members adapted to removably receive the medicament and an expandable stent adapted to receive the tubular members. Also provided is a medicament delivery vehicle, the vehicle comprised of tubular members which receive the medicament wherein the medicament comprises discrete entities and each of said entities are removably positioned at predetermined regions within the members.
Claims19
A stent, comprising:
- an expandable framework configured to be implanted and expanded within a body lumen to support a luminal wall;
- one or more tubular members positioned in a spiral configuration along an inner surface of the expandable framework;
- a plurality of radioactive particles positioned within the one or more tubular members;
- wherein the plurality of radioactive particles are designed to be removable from the one or more tubular members in situ.

A stent comprising:
- a tubular scaffold configured to be implanted and expanded within a body lumen to support a luminal wall;
- a plurality of radioactive seeds;
- one or more non-radioactive spacers;
- and
- one or more tubular members positioned along an inner surface of the tubular scaffold;
- wherein the tubular members receive both the radioactive seeds and the one or more non-radioactive spacers within the tubular members with the one or more non-radioactive spacers positioned between adjacent radioactive seeds to space the radioactive seeds apart within the tubular members, and wherein the radioactive seeds are positioned in a spiral configuration along the inner surface of the tubular scaffold.
