Abstract
A bypass graft incorporates fixation mechanisms at its opposite ends, for securing these ends to different locations along a blood vessel, or alternatively to different locations wherein one of the locations is a different vessel or an organ defining a cavity. Mechanical fixation features such as collets or grommets can be employed, enhanced by delivery of an electrical current sufficient to heat surrounding tissue to form a thermal bond. A graft deployment system includes a tissue dilator and a needle for perforating tissue, mounted coaxially within the dilator. Intralumenal systems further include a catheter for containing the dilator.
Claims20
An anastomotic connector system for connecting a tubular graft to a blood vessel or hollow body organ comprising:
- a collet comprising a tubular collet portion having a proximal end and a distal end, and a plurality of radially self-expanding collet members separate from each other and disposed around the distal end of the tubular collet portion and depending therefrom,
- each of the collet members having a proximal end and a distal end, the distal end of each collet member having a blunt configuration so as to extend along a vessel or body organ wall interior.
