Title
(EN) DEVICE FOR TISSUE REMOVAL
(FR) DISPOSITIF D'EXTRACTION TISSULAIRE
Abstract
(EN)
Improved device and method for safe, accurate, efficient surgical procedures are disclosed. A preferred device is a waveguide assembly for delivering electromagnetic radiation to a tissue comprising a waveguide with a multi-facetted tip and a cap over the 5 multi-facetted tip. Preferably the waveguide is an optical fiber. The cap is a protective, reinforced cap fused to the optical fiber's tip as an integral part of it and comprises an axially-extending portion oriented at a predetermined angle relative to the elongated axis of the optical fiber. A method of manufacturing special waveguide caps is provided. The optical fiber assembly delivers high power electromagnetic radiation in lateral direction 10 with respect to the elongated axis of the optical fiber, determined by the multiple-facetted tip, the slant angles of the optical fiber's core, and the orientation of the cap's axially- extending portion. A method for removing unwanted tissue like in benign prostatic hyperplasia treatments is also provided.

L'invention concerne un dispositif et un procédé améliorés de réalisation sûre, précise et efficace d'opérations chirurgicales. Un dispositif préféré est un ensemble guide d'ondes permettant d'administrer un rayonnement électromagnétique à un tissu comprenant un guide d'ondes disposant d'une extrémité à plusieurs facettes et un bouchon recouvrant l'extrémité à 5 facettes. Le guide d'ondes est de préférence une fibre optique. Le bouchon est un bouchon protecteur renforcé fusionné à l'extrémité de la fibre optique dont il fait partie intégrante, et comprend une partie en prolongement axial orientée selon un angle prédéterminé par rapport à l'axe allongé de la fibre optique. L'invention concerne également un procédé de fabrication de bouchons de guide d'ondes spécifiques. L'ensemble fibre optique administre un rayonnement électromagnétique puissant en direction latérale 10 par rapport à l'axe allongé de la fibre optique, déterminé par l'extrémité à plusieurs facettes, les angles d'inclinaison du noyau de la fibre optique, et l'orientation de la partie en prolongement axial. L'invention concerne par ailleurs une méthode permettant d'éliminer du tissu indésirable par exemple dans le cadre du traitement de l'hyperplasie prostatique.
