Title
(EN) METHODS FOR SELF-CENTERING A GUIDE CATHETER
(FR) DISPOSITIF ET PROCÉDÉS D'AUTO-CENTRAGE D'UN CATHÉTER-GUIDE
Abstract
(EN)
A guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, for treatment of heart conditions such as valvular stenosis. For example, a guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, or any other normal or abnormal passage in the body against the direction flow. This device can also be used to localize and repair leaks where a fluid flow jet is present in submerged or fluid-filled chambers. A device for centering a medical instrument in a body conduit includes a framework of frame members, defining a lumen with open ends; and a covering.

Ce document concerne des dispositifs et des procédés pour le traitement d'affections cardiaques telles que la sténose valvulaire. Il concerne par exemple des dispositifs et des procédés par lesquels un cathéter-guide peut s'aligner lui-même avec un courant d'écoulement de sang pour ainsi aider à diriger un fil-guide ou tout autre dispositif allongé transmis depuis le cathéter-guide à travers un orifice d'une valvule cardiaque.
