The present invention is a catheter device (36) that includes a disruptable guidewire channel (30). The guidewire channel is configured to provide trackability of the catheter along the guidewire (40) during introduction of the catheter to a treatment site. Once treatment is completed, the guidewire channel (30) can then be disrupted so as to free the guidewire from the catheter in situ. The apparatus of the present invention provides advantages over existing over-the-wire and rapid exchange catheter introduction methods, including the ability to achieve much faster treatment in series, the ability to maintain multiple treatment implements simultaneously at a treatment site using a single guidewire (40).

L'invention concerne un dispositif à cathéter qui comprend un canal pour fil-guide amovible. Ledit canal fil-guide est configuré de manière à faciliter la détection nécessaire du cathéter le long du fil-guide, lors de l'introduction du cathéter sur un site de traitement. Une fois que le traitement est terminé, le canal pour fil-guide peut être retiré, de façon à libérer le fil-guide du cathéter in situ. L'appareil de l'invention offre des avantages distincts par rapport aux procédés existants d'introduction du cathéter à échange rapide et sur le fil, comprenant la capacité à réaliser plus rapidement les échanges d'équipement du traitement, la capacité à distribuer des équipements de traitement multiples en série, et la capacité à maintenir les équipements de traitement multiples simultanément sur le site de traitement au moyen d'un fil-guide simple.
