17. A method of delivering an expandable, implantable medical device to a bodily location comprising the steps of:
-
i) providing a medical device delivery apparatus comprising a balloon mounted on a tube, the balloon having protrusions thereon, including inwardly directed protrusions which extend outward upon inflating the balloon. an inflation lumen capable of fluid communication with the balloon, an expandable, implantable medical device disposed about the balloon, at least some of the protrusions on the balloon underlying the expandable, implantable medical device to releasably engage the expandable, implantable medical device;
ii) inserting at least a portion of the apparatus including the balloon and the expandable, implantable medical device into a bodily vessel;
iii) advancing the expandable, implantable medical device and balloon to a desired bodily location;
iv) inflating the balloon to expand the expandable implantable medical device;
v) at least partially deflating the balloon such that the medical balloon no longer engages the expandable, implantable medical device;
vi) withdrawing the apparatus from the body, the expandable, implantable medical device remaining in the body. - View Dependent Claims (18)
