STEERABLE MEDICAL DEVICE HANDLE

摘要

A steerable catheter control handle and method are provided for bi- directional control of a steerable catheter, the catheter including at least two control wires, a distal end of each of the control wires being coupled to the catheter at a distal region thereof. The control system comprises a housing. A wire actuation mechanism is disposed within the housing and is operably coupled to at least two control wires for enabling actuation of the at least two control wires. The steerable catheter control handle additionally comprises a proximal control knob that is operably coupled to the wire actuation mechanism to enable actuation of the at least two control wires. The control knob is positioned proximal to the wire actuation mechanism to enhance ease of use of the steerable catheter control handle. The rotation of the proximal knob causes movement of the wire actuation mechanism within the housing for tensioning one of the at least two control wires for causing a distal end deflection of the steerable catheter.
