Abstract

An elongate hand unit for deploying an elongate implant from the distal end of a delivery catheter. The hand unit has a distal end and a proximal end separated by a hand unit length. The hand unit may include a pull component and a push component. The pull component may include a pull grip sliding on the push component to deploy the implant. The push component may be operatively connected to the push element and include at its proximal end a push surface to receive during deployment of the implant a force that pushes on the push element shaft to resist proximal movement of the implant during deployment. The push component may provide a guide rail that defines a guide path for the pull grip, whereby proximal movement of the pull grip along the guide path deploys the implant.
