Abstract
A delivery apparatus for a prosthetic heart valve includes a handle, one or more actuator drivers, and a gearbox disposed within the handle and coupled to rotate the actuator drivers relative to the handle. The gearbox can include a counter-rotation gear train that can be operated to rotate two sets of actuator drivers in opposite directions. One or more of the actuator drivers can have an associated torque limiter that prevents overloading of the actuator driver. The gearbox can be pivotably mounted within the handle. The gearbox can be configured to engage a stop member within the handle to limit pivoting of the gearbox in a predetermined direction. The handle can include a sensor that is positioned to measure torque applied to the prosthetic heart valve while rotating the actuation drivers.
