Title (EN) A DEVICE AND METHOD FOR INTERSTITIAL LASER ENERGY DELIVERY
(FR) DISPOSITIF ET PROCEDE POUR L'APPLICATION D'ENERGIE LASER INTERSTITIELLE
Abstract:
(EN) Disclosed is a catheter and moveable needle system (15', 15') which places one or more fiber optic elements (23', 23') and thermo-measuring devices (24) through a body passageway wall and into the bulk of an adjacent organ (43). The catheter is positioned adjacent to the organ and the needles are extended to mechanically puncture the wall and move into the organ with the fiber optic elements. The needle may be withdrawn into the catheter before delivery of laser energy or remain in the organ to serve as an aspiration-irrigation vehicle. Lumens (16) provided in the catheter for carrying the hollow needles may likewise be used for aspiration or irrigation of the passageway. A dilation balloon (19, 20) may be provided in order to temporarily fix and support the catheter while the needle is inserted into the organ. The temperature of the area being treated is monitored by thermomeasuring devices provided on the fiber optic elements. Small puncture holes created by the hollow needles heal quickly and minimize risk of infection.
(FR) Cathéter et système d'aiguilles mobiles (15', 15') permettant d'introduire une ou plusieurs fibres optiques (23', 23') et des dispositifs de mesure thermique (24), à travers la paroi d'une voie de passage du corps, dans la masse d'un organe adjacent (43). Ledit cathéter est placé dans une position adjacente à l'organe et les aiguilles sont avancées afin qu'elles perforent mécaniquement la paroi et s'enfoncent dans l'organe avec les fibres optiques. L'aiguille peut être rentrée dans le cathéter avant l'application de l'énergie laser ou rester dans l'organe pour servir de vecteur d'aspiration-irrigation. Des lumières (16) situées dans le cathéter en vue d'offrir un passage aux aiguilles creuses peuvent également être utilisées pour l'aspiration ou l'irrigation de la voie de passage. Ledit cathéter peut être doté d'un ballon de dilatation (19, 20) destiné à maintenir en place et à soutenir le cathéter pendant la pénétration de l'aiguille dans l'organe. La température de la zone traitée est surveillée par des dispositifs de mesure thermique placés sur les fibres optiques. Les petits trous de perforation créés par les aiguilles creuses guérissent rapidement, ce qui minimise les risques d'infection.
