Control handle for steerable catheter
First Claim
1. A steerable catheter comprising(a) a flexible elongated catheter body containing one or more lumens, having proximal and distal ends,(b) a flexible catheter tip fixedly secured to the distal end of the catheter body,(c) an elongated pull wire running through the catheter body having its distal end secured to the catheter tip, and(d) a steerable catheter handle secured to the proximal end of the catheter body wherein said catheter handle is comprised of a mounting shaft containing securing means for securing the proximal end of the pull wire, tensioning means for putting the pull wire in tension and relieving the tension on the pull wire within the catheter body, an adjustment knob containing an internally geared portion which operates in conjunction with the tensioning means to put the pull wire in tension and relieve the tension on the pull wire, a handle grip secured to the mounting shaft and an electrical connector connected to the proximal end of the mounting shaft.
