摘要:
An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.
