Abstract:
A vascular catheter system for guided placement and implanting of a prosthesis within a body passageway, said system comprising:a catheter body having proximal and distal ends, and a proximal and distal region, the proximal region having at least two lumens terminating distally at and in communication with a common lumen in the distal region, such that a guidewire and working element when positioned in said at least two lumens of said proximal region may alternately be advanced into said common lumen;a balloon disposed about the common lumen and communicating with an inflation lumen separate from the common lumen and the two lumens of the proximal region, the inflation lumen extending proximally on the catheter body; andan expandable prosthesis associated with the balloon, said prosthesis having a first diameter which permits intraluminal delivery of the prosthesis into a body passageway and which places the prosthesis in close proximity to the balloon, and a second expanded diameter upon the application of radial, outwardly extending force from the interior of the prosthesis.
