Deployment handle for an implant deployment device
First Claim
1. An implant deployment device handle, including:
- at least one actuator including a coupling element to couple the actuator to a component of an implant deployment device to be withdrawn, wherein the coupling element includes a flexible rack;
wherein the flexible rack is arranged to translate movement of the at least one actuator in a withdrawal direction to corresponding withdrawal of a component coupled thereto.

Abstract
A deployment handle (112) for an implant deployment device (10) facilitates withdrawal of a sheath (18). The deployment handle (112) includes two separate actuators: a trigger (130) and a sliding actuator (330). The trigger (130) can be used to effect small step-wise movement of a carriage (120) that is connected to a sheath (18) to be withdrawn. The sliding actuator (330) can be used to effect continuous movement of a carriage (120) to withdraw a sheath (18). In order to transmit movement of either the trigger (130) or the sliding actuator (330) to the carriage (120), a flexible rack (380) is used. The flexible rack (380) includes upper teeth (390) and lower teeth (395) for engagement with the trigger (130) and the sliding actuator (330) respectively. The ability of the flexible rack (380) to bend back on itself means that unnecessary elongation of the deployment handle (112) is avoided.
