Selective coating of medical devices

A method of manufacturing a drug eluting stent, comprising:

• applying a first composition to a first end of a stent wherein the first composition covers up to a selected length of the stent;
• rotating the stent in a centrifuge device to provide sufficient centrifugal force to distribute the first composition at least along the length of the stent that has been exposed to the first composition;
• allowing the first composition to solidify to form a first coating;
• applying a second composition to a second end of the stent wherein the second composition covers at least a portion of the remaining length of the stent not covered by the first coating;
• rotating the stent in the centrifuge device to provide sufficient centrifugal force to distribute the second composition at least along a portion of the remaining length of the stent;
• and
• allowing the second composition to solidify to form a second coating on the stent.

A method of coating a tubular implantable medical device, comprising:

• applying a first coating substance to a tubular implantable medical device along a first length of the device;
• rotating the device about an axis of rotation to provide sufficient centrifugal force to distribute the first coating substance along the first length;
• applying a second coating substance to the device along a second length of the device, the second length being free of the first coating substance;
• and
• rotating the device about an axis of rotation to provide sufficient centrifugal force to distribute the second coating substance along the second length.

A method of coating an implantable medical device, comprising:

• applying a first composition to a first end of an implantable medical device wherein the first composition covers up to a selected length of the medical device;
• rotating the medical device in a centrifuge device to provide sufficient centrifugal force to distribute the first composition at least along the length of the medical device that has been exposed to the first composition;
• applying a second composition to a second end of the medical device wherein the second composition covers at least a portion of the remaining length of the medical device not covered by the first composition;
• rotating the medical device in the centrifuge device to provide sufficient centrifugal force to distribute the second composition at least along a portion of the remaining length of the medical device.
