Abstract
The invention concerns an assembly for by-pass surgery. The assembly comprises a laser catheter. The laser catheter comprises: a tubular arrangement of optical fibres having distal ends defining a ring-shaped emitting surface arranged for emitting a tubular bundle of laser beams in a distal direction of the catheter; and a gripper for gripping tissue inside the tubular bundle of laser beams, having a gripping end defining the location where gripped tissue is held, the gripping end being arranged inside the tubular bundle and proximally from the emitting surface. The distance between the emitting surface and the gripping end is at least 1 mm.
Claims22
Assembly for by-pass surgery on a target vessel having a vessel wall comprising a laser catheter, which laser catheter comprises:
- a tubular arrangement of optical fibres having distal ends defining a ring-shaped emitting surface arranged for emitting a tubular bundle of laser beams in a distal direction of the catheter;
- a gripper for gripping tissue inside the tubular bundle of laser beams, having a gripping end defining the location where gripped tissue is held, the gripping end being arranged inside the tubular bundle and proximally from the emitting surface,
- characterized in that
- the distance between the emitting surface and the gripping end is equivalent to a thickness of the wall of the target vessel.
