Abstract
A percutaneous trans-luminal catheter delivery system for an implant. The system includes a catheter shaft with a distal end to carry the implant and an elongate housing at a proximal end that an operator can grasp when deploying the implant. The shaft has an inner push component which can push on the implant in a distal direction and an outer sheath component which radially surrounds the implant until deployment of the implant into the bodily lumen. The outer sheath component is capable of being pulled proximally, from the housing, to deploy the implant, the housing being mounted on a proximal end portion of the push component and defining a channel. The housing may contain a sheath slitter that is fixedly mounted relative to the length of the channel that can slit the outer sheath as the outer sheath is caused to move proximally in the channel relative to the slitter.
