Abstract

A multiple stent structure including a plurality of stent bodies arranged end to end in which adjacent stent bodies of the structure are connected by a severable connecting portion disposed between the adjacent stent bodies is disclosed. A method of coating a plurality of stents including depositing a coating on the multiple stent structure and severing the severable connecting portions to disconnect the plurality of stent bodies is disclosed.

First claim

What is claimed is:

1. A method of coating a plurality of stents comprising:
providing a structure comprising a plurality of stent bodies arranged end to end, wherein adjacent stent bodies along the structure are connected by a severable connecting portion disposed between the adjacent stent bodies, the severable connecting portion comprising a tube disposed between the adjacent stent bodies, a first gate connecting the tube to one of the adjacent stent bodies, and a second gate connecting the tube to the other adjacent stent body, wherein the first and second gates are adapted to sever from the adjacent stent bodies or are adapted to break along a segment of the gates;
depositing a coating on the plurality of stent bodies; and
severing the first and second gates to disconnect the plurality of stent bodies, wherein the tube is not part of a final stent product to be implanted in a patient.

2. The method of claim 1 , wherein at least one of the stent bodies at an end of the structure comprises a severable end portion at the end of the structure.

3. The method of claim 2 , further comprising severing the severable end portion from the at least one of the stent bodies after depositing the coating.

4. The method of claim 2 , wherein the severable end portion is mounted over a rotatable member that supports and rotates the structure during the depositing of the coating, wherein the rotatable member does not contact any of the stent bodies.

5. The method of claim 2 , wherein at both ends of the structure a stent body comprises the severable end portion at the respective end of the structure, and wherein a mandrel disposed within the structure engages the severable end portion at each end of the structure to support the structure during the depositing of the coating.

6. The method of claim 5 , wherein at least one end of the mandrel engages a rotatable member that rotates the mandrel and the structure during the depositing of the coating.
