ABSTRACT:
A method and apparatus for affixing an endoluminal device to the walls of tubular structures within the body is disclosed which utilizes incremental inflation of a balloon cuff to deploy radially projecting barbs attached to the cuff within a plurality of recesses. At lower levels of cuff pressure, the engagement of the outer surface of the cuff with the tubular structure temporarily holds the device in place without tissue damage because the outer extremity of the barbs do not extend beyond the cuff's outer surface. If the device requires repositioning, then the cuff is easily deflated and moved to a new location and is again partially inflated. Once the location of the device has been found to be optimal, the cuff is fully inflated so as to deploy the barbs to permanently fix the device in place.
