Abstract

Claims10
A vascular system comprising a catheter having a first end portion, a second end portion at the opposite end of the catheter and a plurality of independent lumens, the first end portion dimensioned for insertion into a vascular graft such that the plurality of lumens are in fluid communication with the vascular graft and the second end portion dimensioned for insertion into a vein of a patient such that the plurality of lumens are open to and in communication with the vein to create a conduit from an artery to the vein further comprising a connector, the connector connecting the catheter to the graft;
- wherein the connector comprises a slidable locking member movable between a first position and a second position to compress the graft against an exterior surface of the catheter;
- wherein the exterior surface of the catheter has a raised surface and in the second position, the locking member clamps the graft against a raised surface of the catheter so the graft is positioned between the locking member and the raised surface.
A method for providing a vascular conduit from a patient's artery to vein comprising:
- providing a catheter having at least two lumens and a raised surface;
- inserting a first region of the catheter into a graft connected to an artery of the patient;
- connecting a first region of the catheter to the graft by sliding a locking ring over the raised surface of the catheter to clamp the graft between the locking ring and raised surface;
- and
- inserting a second region of the catheter through a vein of the patient and through a vascular system.
