Title
(EN) LOW-PROFILE STEERABLE CATHETER
(FR) CATHÉTER ORIENTABLE À FAIBLE ENCOMBREMENT
Abstract
(EN)
A steerable catheter (220) comprises a flexible tube (222) having a proximal portion and a distal portion and comprising a circumferential wall (228) that defines an elongate lumen (230) between the proximal portion and the distal portion. A pull-wire (224) extends in association with the wall, from the proximal portion to the distal portion. A pull¬ ring (226) is coupled to the wall at the distal portion such that the pull-ring circumscribes the lumen, and is coupled to the pull-wire (224), such that pulling on the pull-wire bends the distal portion. The pull ring (226) has (i) a first state in which the pull-ring is elliptical and has a first eccentricity, and a second state in which the pull-ring is elliptical and has a second eccentricity that is smaller than the first eccentricity. The pull ring (226) is biased toward the first state and is deformable to the second state.
(FR)
L'invention concerne un cathéter orientable (220) comprenant un tube souple (222) comportant une partie proximale et une partie distale et comprenant une paroi (228) circonférentielle qui délimite une lumière (230) allongée entre la partie proximale et la partie distale. Un fil de traction (224) s'étend, en association avec la paroi, de la partie proximale à la partie distale. Une bague de traction (226) est accouplée à la paroi au niveau de la partie distale de façon à ce que la bague de traction circonscrive la lumière, et est accouplée au fil de traction (224) de façon à ce que la traction exercée sur le fil de traction fasse fléchir la partie distale. La bague de traction (226) peut présenter (i) un premier état dans lequel la bague de traction est elliptique et possède une première excentricité, et (ii) un second état dans lequel la bague de traction est elliptique et possède une seconde excentricité qui est plus petite que la première excentricité. La bague de traction (226) est sollicitée vers le premier état, et est déformée jusqu'à atteindre le second état.
