ABSTRACT:
A thermoplastic member such as a length of tubing for forming a catheter balloon is sealed by radiant heat to a thermoplastic shaft of a medical device such as a Foley catheter. Radiant heat is supplied as a narrow annular band by an apparatus which also automatically locates portions of the shaft at the narrow annular band. A length of shrink tubing is placed over the balloon tubing and adjoining portions of the shaft, is then preshrunk while at that location, and is further shrunk therearound and is subjected to radiant heat by the apparatus in order to seal the balloon tubing onto the shaft and complete assembly of a balloon catheter. It is especially preferred that the shrink tubing be tinted so as to enhance the seal formed beneath the shrink tubing.
