Abstract
The invention features a method of depositing a coating on a medical device. The method includes: a) placing the medical device in an evacuated chamber, b) introducing a noble gas into the chamber, c) providing at least one target in the chamber, spaced from the device, and d) sputter depositing a coating onto the device by applying power to the target so that the noble gas forms a plasma in the vicinity of the target and material is sputtered from the target by ion bombardment and deposited on the device. In another aspect, the invention features a medical device having a coating deposited by a plasma sputtering process. Preferably, the coating is a calcium containing compound.
