Summary:A catheter for diagnosing or treating the vessels found within a body or body space includes a center strut that is bonded, preferably thermally, along its longitudinal axis with the thermoplastic tubular member within which it is housed. The tubular member preferably has three layers: an inner layer, a braided layer and an outer layer. The composite catheter is made using a process in which two half-cylinder shaped mandrels are placed on each side of the center strut while the strut is heated in order to cause the thermal bonding. The bonded center strut provides in-plane deflection and improved transfer of torque to the tip of the catheter. Un cathéter servant au diagnostic ou au traitement de vaisseaux à lintérieur dun corps ou dun espace corporel comprend un montant central qui est lié, préférablement thermiquement, le long de son axe longitudinal avec lélément tubulaire thermoplastique dans lequel il est logé. Lélément tubulaire comporte préférablement trois couches : une couche intérieure, une couche tressée et une couche extérieure. Le cathéter composite est fait au moyen dun procédé dans lequel deux mandrins en forme de demi-cylindre sont placés sur chaque côté du montant central pendant que le montant est chauffé afin de provoquer la liaison thermique. Le montant central lié fournit une déviation sur le plan et un transfert amélioré du couple à lextrémité du cathéter.
