Title
(EN) DEVICES FOR TREATING A STRICTURE ALONG THE BILIARY AND/OR PANCREATIC TRACT
(FR) DISPOSITIFS DE TRAITEMENT D'UNE STÉNOSE LE LONG DU TRACTUS BILIAIRE ET/OU DU TRACTUS PANCRÉATIQUE
Abstract
(EN) Medical devices and systems for treating a stricture, for example along the biliary and/or pancreatic tract, are disclosed. An example system may include a guidewire having a distal end and defining a lumen. A stiffening rod may be slidably disposed within the lumen. The stiffening rod may have a distal end and a distal end region disposed adjacent to the distal end. The stiffening rod may be configured to shift between a first position where the distal end of the stiffening rod is disposed proximally of the distal end of the guidewire and a second position where the distal end of the stiffening rod is disposed distally of the distal end of the guidewire.
(FR) Des dispositifs et des systèmes médicaux de traitement d'une sténose, par exemple le long du tractus biliaire et/ou pancréatique, sont divulgués. Un système donné à titre d'exemple peut comprendre un fil-guide présentant une extrémité distale et définissant une lumière. Une tige de raidissement peut être disposée de manière coulissante à l'intérieur de la lumière. La tige de raidissement peut présenter une extrémité distale et une région d'extrémité distale disposée adjacente à l'extrémité distale. La tige de raidissement peut être conçue pour se déplacer entre une première position dans laquelle l'extrémité distale de la tige de raidissement est disposée de manière proximale par rapport à l'extrémité distale du fil-guide et une seconde position dans laquelle l'extrémité distale de la tige de raidissement est disposée de manière distale par rapport à l'extrémité distale du fil-guide.
