ABSTRACT:
An implant which includes an elongated member to be situated in the interior of a tubular body organ and carrying at its exterior a structure for promoting the ingrowth of tissue, this structure being situated inwardly from a free end of the elongated member which enters the tubular organ in advance of the ingrowth structure. Between this free end of the elongated member and the ingrowth structure are barbs which are fixed to the elongated member, which are circumferentially distributed about the latter, and which are inclined away from the free end of the elongated member and extend over the ingrowth structure. These barbs are flexible so that they are capable of being radially deflected toward the elongated member. When the elongated member is to be introduced into the tubular organ, the latter is gripped with tweezers which have teeth which engage the tubular organ and which are circumferentially distributed about the latter. The tweezer teeth are out of longitudinal alignment with the barbs so that when the teeth and barbs pass each other during introduction of the implant into the tubular organ, while the latter is pulled onto the elongated member with the tweezers, the tweezer teeth will be aligned with spaces between the barbs.
