Multi-directional steerable catheters and control handles



Multi-directional steerable catheters and control handles



Official Gazette of the United States Patent & Trademark Office Patents 1243(1), Feb 6



A steerable catheter comprises a catheter body, a tip section mounted to the distal end of the catheter body, and a control handle mounted to the proximal end of the catheter body. The control handle comprises a housing having a piston chamber and a piston slidably mounted in the piston chamber. The piston is longitudinally movable between proximal and distal positions. A longitudinal groove having proximal and distal ends and extends along a portion of the length of the piston. A puller wire anchor is slidably disposed within the longitudinal groove. A puller wire extends from the control handle, through a lumen in the catheter body and into a lumen in the tip section. The proximal end of the puller wire is fixedly attached to the puller wire anchor. A set screw is fixedly attached to the handle housing and extends radially inwardly into the longitudinal groove in the piston. When the piston is slid distally relative to the handle housing, the set screw prevents the puller wire anchor from moving distally with the piston, resulting in deflection of the tip section in the direction of the side to which the puller wire is anchored.
