ABSTRACT:
A catheter introducer for antegrade and retrograde medical procedures includes a generally tubular introducer member having proximal and distal ends. The introducer member includes a lumen for receiving a guidewire during a medical procedure, which guidewire includes a distal end traveling in a first direction. The catheter introducer further includes an occlusion member adjacent the distal end thereof for altering the traveling direction of the distal end of the guidewire to a second direction. The catheter introducer of the invention can be easily used for performing angioplasty on tandem or segmental lesions in one procedure using antegrade and retrograde approaches. The novel technique of the present invention involves performing angioplasty on one lesion using one of the antegrade and retrograde approaches, and then using the other of the antegrade and retrograde approaches to perform angioplasty on the second lesion. Both lesions are attended to during one medical procedure.
