Abstract
Disclosed herein is a medical tool adapted to engage and disengage with leadless pacemakers to allow for the repeated use of the tool in delivering and implanting multiple leadless pacemakers into a patient heart in a serial or repeated manner. The tool includes a handle, an attachment mechanism, a torque portion, and a rotation limiter. The handle includes a housing. The attachment mechanism is operably coupled to the housing and configured to actuate between a released state and an engaged state. The torque portion is operably coupled to the housing and rotatable relative to the housing to transition the attachment mechanism between the released and engaged states. The torque portion includes a shaft. The rotation limiter is in sliding engagement with the shaft between a first stop and a second stop. The rotation limiter includes a first helical thread. The tool also includes a second helical thread in threaded engagement with the first helical thread and operably coupled to the housing. Rotation of the torque portion rotates the rotation limiter such that the first helical thread is rotated against the second helical thread, thereby driving the rotation limiter along the shaft b…
