Title
(EN) STEERABLE SPHINCTEROTOME AND METHODS FOR CANNULATION, PAPILLOTOMY AND SPHINCTEROTOMY
(FR) SPHINCTEROTOME ORIENTABLE ET PROCEDES DE CANNULATION, DE PAPILLOTOMIE ET DE SPHINCTEROTOMIE
Abstract
(EN) The present invention relates to methodology of an apparatus for accurately positioning devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. The sphincterotome with a steerable or adjustable distal segment of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to one embodiment of the present invention, a threaded portion of a cable assembly cooperates with a torque transmission element and a cog to enable the operator to rotate a cutting wire into a desired position relative to the catheter. Alternate embodiments allow the operator to fix the depth of a needle knife while allowing, if desired, accurate rotational positioning of the associated catheter. Threaded stabilizing elements, pivot elements and a steering wire may be used together or individually to accomplish these features. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.
(FR) La présente invention se rapporte à une méthode et à un appareil permettant de positionner précisément des dispositifs en vue de l'exécution d'une cannulation, d'une papillotomie et d'une sphinctérotomie endoscopique et de procédures similaires. Le sphinctérotome de la présente invention est doté d'un segment distal orientable ou réglable et il permet au praticien de contrôler la position de l'extrémité distale du dispositif indépendamment de l'endoscope et de compenser des incohérences du dispositif et de l'anatomie. Conformément à un mode de réalisation de la présente invention, une partie filetée d'un ensemble à câble coopère avec un élément de transmission de couple et un engrenage pour permettre à l'opérateur de faire tourner un fil métallique coupant jusqu'à une position souhaitée par rapport au cathéter. D'autres modes de réalisation permettent à l'opérateur de fixer la profondeur d'une lame-aiguille tout en permettant, si nécessaire, un positionnement en rotation précis du cathéter associé. Des éléments stabilisateurs filetés, des éléments à pivot et un fil d'orientation peuvent être utilisés ensemble ou individuellement pour mettre en oeuvre ces caractéristiques. Les produits actuellement disponibles qui peuvent être modifiés conformément à la présente invention comprennent, non exclusivement, les sphinctérotomes et les lames-aiguilles de Boston Scientific.
