DEFLECTABLE CATHETER WITH HINGE

摘要

A deflectable device, such as a catheter, is provided that includes a hinge that enhances the ability of the device to deflect or bend within a predetermined plane. The catheter comprises an elongated tubular catheter body having proximal and distal ends and at least one lumen extending therethrough. A distal segment is provided distal to the distal end of the catheter body. A tubular hinge is provided between the distal end of the catheter body and the proximal end of the distal segment. The hinge has an axis and at least one lumen extending therethrough. The tube includes at least one slot, and preferably a plurality of slots, extending part of the way through the hinge generally transverse to the axis of the hinge.

1. A deflectable device comprising an elongated tubing having proximal and distal ends, an axis, at least one lumen extending therethrough, a distal region at or near the distal end of the deflectable device, and an intermediate region between the proximal region and distal region, wherein the tubing includes at least one slot extending part of the way through the tubing in the intermediate region, the at least one slot being generally transverse to the axis of the tubing, wherein the tubing is adapted to bend in a single plane in a single direction; and
means for deflecting the distal region of the tubing in a plane that passes through the at least one slot.
