ABSTRACT:
A vessel-loop having an elastic tube and a needle attached to one end thereof for use in various surgical procedures, and a method for forming same. The method includes the steps of positioning a heat-sensitive element within a section of elastic tubing, applying tensile forces to the opposed ends of the tubing section, and heating the heat-sensitive element and the portion of the tubing adjacent the heat-sensitive element so that the heat-sensitive element adheres to the adjacent tubing portion. The heat-sensitive element and the adjacent tubing portion are allowed to cool until a conjoined reduced-diameter portion is formed. The reduced-diameter portion is cut to form two ends, each having a reduced-diameter end. The reduced-diameter ends are then each secured to a needle, forming two vessel loops.
