Selectively coated stent delivery system and method of manufacture thereof

摘要

The invention is directed to a stent delivery system having a coating selectively applied thereto. The stent delivery system has an expandable device with a stent. The coating may coat all portions of the expandable device except those areas under the stent. The coating may selectively coat areas under the stent in order to aid in stent deliverability and/or deployment. The coating may partially cover the stent in order to aid stent deliverability and stent fixation on the catheter. The coating may be a lubricious material, such as a hydrophilic material. The coating may be applied through various techniques, including the use of templates such as elastic bands that shield selected areas of the catheter.
