A therapeutic catheter and method used in percutaneous transluminal coronary angioplasty with the catheter comprising a shaft (5) a soft tip assembly. The assembly consists of a transition tube (15), a soft tip tube (20), and plug tube (25). The assembly is surrounded by a shrink wrap means. An infrared source (45) is applied to the interface of the shaft (5) and transition tube (15) with the heat being propagated to the transition tube (15) and the soft tip tube (20). The transition tube (15) is formed of materials having a tensile strength of at least 150 % of the materials comprising the soft tip tube (20).
Cathéter thérapeutique et procédé utilisés lors d'angioplastie coronaire transluminale percutanée, ledit cathéter comprenant un ensemble pointe souple, et une tige (5). L'ensemble est constitué d'un tube intermédiaire (15), d'un tube (20) à pointe souple et d'un tube de raccordement (25); un dispositif d'enveloppe rétractable entoure cet ensemble. Une source infrarouge (45) est appliquée sur l'interface de la tige (5) et du tube intermédiaire (15), la chaleur se propageant vers le tube intermédiaire (15) et le tube (20) à pointe souple. Le tube intermédiaire (15) est réalisé dans des matières dont la résistance à la traction représente au moins 150 % des matières constituant le tube (20) à pointe souple.
