Abstract

An expandable catheter accommodates a medical device that is being removed from a body with a larger diameter than the catheter. The same catheter may be used to reposition a device within the body to an alternative delivery site. A catheter or sheath may be used to deliver a medical device, surgical instrument, or biological sample.
