Abstract
The current invention discloses a catheter and a method for delivering a stentless bloprosthesis in a body channel, the method comprising percutaneously introducing a catheter into the body channel, wherein the catheter contains said stentless bloprosthesis at a retracted state; and disengaging said stentless bioprosthesis out of a distal opening of the catheter by a pulling mechanism associated with the catheter structure.
Claims7
A catheter for delivering a longitudinally collapsible prosthesis to an anatomical site in a body channel, the catheter comprising:
- a catheter shaft, the catheter shaft having a distal end, a proximal end, and a lumen between the distal end and the proximal end;
- a handle attached to the proximal end of the catheter shaft;
- an elongated delivery member located inside the lumen, the elongated delivery member having an engaging element at a distal end of the elongated delivery member, wherein the engaging element is adapted for engaging and disengaging a distal portion of the longitudinally collapsible prosthesis;
- a delivery mechanism at the handle coupled to the elongated delivery member, the delivery mechanism being adapted for pulling the distal portion of the longitudinally collapsible prosthesis out of the catheter shaft during a deployment stage.
