Abstract:
1. A method of coupling a catheter to a stem, the method comprising: providing a stem extending longitudinally between a proximal end and a distal end, the stem including at least one enlargement positioned between the proximal end and the distal end of the stem; positioning a catheter over the at least one enlargement and over a region of the stem having a constant outside diameter that is proximal to the at least one enlargement; mating a first portion of a collar with the stem to thereby advance a distal end of the collar past the at least one enlargement to a position over the region of the stem that is proximal to the at least one enlargement; and compressing a portion of the catheter that is positioned over the region of the stem that is proximal to the at least one enlargement to generate a maximum compressive stress in the catheter adjacent to the enlargement.
