Abstract

An apparatus for vessel transfer comprising a tubular outer member and an inner slidable member one of which is rigid and the other of which is flexible. After the apparatus has been inserted in the body tissue, the rigid member is withdrawn from the body leaving the flexible member in place. A vein, prosthesis or elastomeric tubing attaching structure is secured to the end of the flexible member so that the flexible member can be used to pull said vein, prosthesis or elastomeric tubing through the body tissues to an elected distant site where the tip of the flexible member has been surgically exposed.
