Abstract
A catheter system for use in bypassing a block in an artery comprises four components. These components are an arterial catheter, an intravenous ultrasound catheter, a guide wire system, and finally a covered stent used as graft. The bypassing of the block in the artery which extends along a vein comprises the steps of forming a first connection between said artery and said vein proximal to the block in the artery, forming a second connection between said artery and said vein distal to the block in the artery, introducing a covered stent through said artery proximal to the block therein, through said first connection into said vein, via said vein to and through said second connection, and into said artery distal to the block therein, such that a proximal end of the covered stent is positioned in the artery proximal to the block therein and a distal end of the covered stent is positioned in the artery distal to the block therein, and fixing the proximal and distal ends of the covered stent within the artery.
