    摘要: A delivery system for implanting a leadless cardiac pacemaker into a patient is provided. The cardiac pacemaker can include a docking or delivery feature having a through-hole disposed on or near a proximal end of the pacemaker for attachment to the delivery system. In some embodiments, the delivery catheter can include first and second tethers configured to engage the delivery feature of the pacemaker. The tethers, when partially aligned, can have a cross-sectional diameter larger than the through-hole of the delivery feature, and when un-aligned, can have a cross-sectional diameter smaller than the through-hole of the delivery feature. Methods of delivering the leadless cardiac pacemaker with the delivery system are also provided.

    摘要: A delivery system for delivering and mounting a cardiac harness having electrodes on a heart including an elongate body having a proximal portion and a distal portion. The body includes a cavity sized to contain the cardiac harness and electrodes in a compacted configuration and also includes a plurality of elongate push rods movable with respect to the body. The cardiac harness and electrodes are releasably connected to the push rods such that, advancement of the push rods in a distal direction moves the cardiac harness and electrodes from a compacted configuration, within the cavity, to an expanded configuration, outside the cavity. The apparatus also includes a releasing member for releasing the connections between the push rods and the cardiac harness and electrodes upon actuation of the releasing member by a user.
