Deployment handle for an implant deployment device
First Claim
1. An implant deployment device handle, including:
- a first actuator and a second actuator;
a coupling element to couple the first actuator and the second actuator to a component of an implant deployment device to be withdrawn, wherein the coupling element includes a double-sided flexible rack, the flexible rack including a first surface and a second surface opposite the first surface and a first set of teeth on the first surface and a second set of teeth on the second surface;
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;
wherein the first actuator is operable to withdraw a component of an implant deployment device coupled thereto by a first distance by a single actuation thereof;
wherein the second actuator is operable to withdraw a component of an implant deployment device coupled thereto by a second distance by a single actuation thereof;
wherein the second distance is greater than the first distance, and wherein the first actuator is operable to be actuated a plurality of times in order to withdraw the component by the second distance.

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(130) can be used to effect small step-wise movement of a carriage (120) that is connected to a sheath (18) to be withdrawn.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.
