Abstract:
A method for making nested tubing sections, comprising the steps of:providing an inner tubular member having a proximal end, a distal end, and a lumen therebetween; heat-bonding a beading into the lumen of the inner tubular member to seal the distal end; heat-bonding a tubular sleeve circumferentially about the distal end of the inner tubular member, so that the distal end of the tubular sleeve and the distal end of the inner tubular member are substantially aligned; providing an outer tubular member having a proximal end, a distal end, and a lumen therebetween; nesting the inner tubular member within the lumen of the outer tubular member so that the distal end of the tubular sleeve, the distal end of the inner tubular member, and the distal end of the outer tubular member are all substantially aligned with one another; and heat-bonding the outer tubular member to the tubular sleeve.
