Translation Catheters, Systems, and Methods of Use Thereof

摘要

The present teachings generally relate to translation catheter systems and method of using thereof in treating defective mitral valves. Specifically, a translation catheter system includes a catheter configured to move substantially laterally along the mitral annulus and the lateral movement of the catheter is substantially continuous and substantially adjustable. Accordingly, a method of using such a translation catheter includes advancing a first wire across the mitral annulus at a first treatment location, delivering a catheter at or near the first treatment location, moving the catheter substantially laterally to a second treatment location, and advancing a second wire across the mitral annulus, where the distance between the first and second treatment locations is substantially adjustable and optionally visualized.

1. A catheter system comprising:
a first wire configured to be positioned at a first location; a translatable catheter configured to be positioned at a second location and be movable between a first position at which the translatable catheter is at or proximate the first location and a second position at which the translatable catheter is at the second location; and a translation element configured to move the translatable catheter from the first position to the second position in a substantially linear fashion, while the first wire is maintained at the first location.
