Abstract
A stent mandrel fixture for supporting a stent during the application of a coating substance is provided.
Claims11
An apparatus for supporting a stent during the process of applying a coating substance to the stent, comprising:
- a mandrel having a hollow tubular body and pores disposed on the surface of the mandrel, the pores extending through the body and configured to receive a coating substance;
- a vacuum device in fluid communication with the mandrel for extracting the coating substance that is applied to the stent;
- and
- a coupling for allowing the mandrel to rotate with respect to the vacuum device.
1 more element
An apparatus, comprising:
- a first member to support a first end of a stent;
- a second member to support a second end of the stent;
- a third member connecting the first member to the second member and extending through a longitudinal bore of the stent, the third member having a longitudinal bore, and the third member having pores on a surface of the third member, the pores extending all the way through the surface to the bore;
- and
- a vacuum device in fluid communication with the bore of the third member to apply a vacuum pressure so as to extract any excess coating substance that is applied to the stent during a process of coating the stent.
2 more elements
A stent coating device, comprising:
- a mandrel for being inserted at least partially through a longitudinal bore of a stent, the mandrel having a hollow tubular body and pores formed on the surface of the mandrel, the pores extending all the way through the body and configured to receive a coating composition;
- a vacuum device in fluid communication with the mandrel for collecting excess coating composition that is applied to the stent;
- and
- a means for rotating the mandrel about a longitudinal axis of the stent.
