Title: (DE) CHIRURGISCHE VORRICHTUNG ZUR ABGABE VON ENERGIE
(EN) CATHETER FOR DELIVERY OF ENERGY TO A SURGICAL SITE
(FR) CATHETER POUR FOURNIR DE L'ENERGIE A UN CHAMP OPERATOIRE
Abstract:
(EN) A catheter for delivering energy to a surgical site is disclosed. The catheter includes at a proximal end a handle and at a distal end a probe. The catheter includes at least one energy delivery device and an activation element. The at least one energy delivery device is located at the distal end of the catheter to deliver energy to portions of the surgical site. The activation element is located at the distal end of the catheter, to transition the probe from a linear to a multi-dimensional shape, within the surgical site. Methods for deploying the probe from the linear to multi-dimensional shape are disclosed. In another embodiment of the invention the catheter includes a heating element fabricated on a substrate by photo-etching to deliver thermal energy to portions of the surgical site. In another embodiment of the invention the catheter includes an energy delivery element, a tip and a blade. The energy delivery element is located at the distal end of the catheter to deliver energy to portions of the intervertebral disc. The blade is positioned within a first lumen of the tip and is extensible beyond the tip, to cut selected portions within the intervertebral disc. In another embodiment of the invention a catheter includes both energy and material transfer elements and an interface on the handle thereof. The interface couples the energy delivery element and the material transfer element to external devices for energy and material transfer to and from the intervertebral disc.
(FR) L'invention concerne un cathéter permettant de fournir de l'énergie à un champ opératoire. Ce cathéter comprend une poignée au niveau de son extrémité proximale, et une sonde au niveau de son extrémité distale, ainsi qu'un dispositif pour fournir de l'énergie et un élément d'activation. Le dispositif pour fournir de l'énergie est placé au niveau de l'extrémité distale de ce cathéter, de manière à fournir de l'énergie à certaines parties dudit champ opératoire. L'élément d'activation est disposé au niveau de l'extrémité distale du cathéter, ce qui permet à la sonde de passer d'une forme linéaire à une forme multidimensionnelle à l'intérieur du champ opératoire. L'invention concerne également des procédés permettant de déployer cette sonde, celle-ci passant ainsi d'une forme linéaire à une forme multidimensionnelle. Dans un autre mode de réalisation de cette invention, ledit cathéter comprend un corps de chauffe fabriqué sur un substrat par photogravure, ce corps étant destiné à fournir de l'énergie thermique à certaines parties dudit champ opératoire. Dans une variante, ce cathéter est pourvu d'un élément pour fournir de l'énergie, d'un embout, et d'une lame, ledit élément pour fournir de l'énergie étant placé au niveau de l'extrémité distale du cathéter afin de pouvoir fournir de l'énergie à certaines parties du disque intervertébral. On place ladite lame dans un premier espace ménagé à l'intérieur de l'embout, cette lame pouvant s'étendre au-delà de cet embout de manière à sectionner certaines parties du disque intervertébral. Dans un autre mode de réalisation de cette invention, un cathéter comprend des éléments de transfert d'énergie et de matière, ainsi qu'un raccord situé sur sa poignée. Ce raccord permet de coupler ledit élément pour fournir de l'énergie, ainsi que l'élément de transfert de matière, à des dispositifs extérieurs, afin de transférer l'énergie et la matière vers le disque intervertébral ou depuis celui-ci.
