Title
(EN) TRANSLUMENAL CIRCUMFERENTIAL ENERGY DELIVERY DEVICE
(FR) DISPOSITIF DE LIBERATION TRANSLUMINALE ET CIRCONFERENTIELLE D'ENERGIE
Abstract
(EN)
A probe for translumenal circumferential delivery of energy through a biological lumen comprises a catheter which is constructed and arranged to be placed within a particular biological lumen. A plurality of guide channels are formed within the catheter extending from near the proximal end to near the distal end of the catheter. The guide channels include respective diverting regions near the distal end which bend radially toward the circumference of the catheter. Energy delivery devices, such as optical fibers or electrical conductors, are placed within the guide channels and transmit energy to the distal end of the device. The energy delivery devices have relatively flexible portions near the distal ends such that when extended through the diverting region of the guide channels they are deflected radially in a direction to intersect the circumference of the biological lumen. An adaptor is coupled with the energy delivery device to supply energy for transmission to the tissue at the distal end of the device. Thus, the energy delivery device may be positioned in a withdrawn position in the catheter so that the distal end of the energy delivery device lies within the guide channel, and in an extended position so that the distal end of the energy delivery device is diverted by the diverting region of the guide channel and extends into the tissue to be treated.

Une sonde de libération transluminale et circonférentielle d'énergie à travers une lumière biologique comprend un cathéter conçu pour être placé dans une lumière biologique particulière. Ledit cathéter contient une pluralité de canaux de guidage s'étendant depuis un point à proximité de l'extrémité proximale jusqu'à un point proche de l'extrémité distale du cathéter. Les canaux de guidage présentent des régions de déviation respectives situées à proximité de l'extrémité distale et courbés radialement vers la circonférence du cathéter. Des dispositifs de libération d'énergie tels que des fibres optiques ou des conducteurs électriques sont placés dans les canaux de guidage et envoient de l'énergie à l'extrémité distale du dispositif. Ces dispositifs de libération d'énergie comprennent des parties relativement souples à proximités des extrémités distales de sorte que lorsque ces parties sont déployées dans la région de déviation des canaux de guidage elles se courbent radialement dans un sens dans lequel elles coupent la circonférence de la lumière biologique. Un adaptateur est couplé au dispositif de libération d'énergie de sorte qu'il fournisse de l'énergie destinée à être transmise au tissu au niveau de l'extrémité distale du dispositif. Ainsi, le dispositif de libération d'énergie peut être mis en position de retrait dans le cathéter de sorte que l'extrémité distale de celui-ci reste dans le canal, et en position déployée de sorte que l'extrémité distale dudit dispositif soit déviée par la région de déviation du canal de guidage et s'étende dans le tissu à traiter.
