ABSTRACT:
The present invention provides a catheter apparatus, an improved introducer system, and a methodology for creating a bypass on-demand between an unobstructed blood vessel such as the aorta and an obstructed blood vessel such as an obstructed coronary artery in-vivo using a prepared shape-memory alloy cuff and a graft segment in tandem as a shunt. The invention allows the placement and creation of single or multiple bypass grafts without use of a heart-lung machine and without need for stopping the heart of the patient during the coronary artery bypass surgery.
