DELIVERY SYSTEMS AND METHODS FOR SHEATHING AND DEPLOYING AN IMPLANTABLE DEVICE
First Claim
1. A delivery system for sheathing a crimpable implantable device and deploying the implantable device within a body of a patient, the delivery system comprising:
- a delivery device to position and deploy the implantable device, the delivery device having a tubular member configured to receive and house the implantable device in a crimped state for delivery to a target location within the body of the patient, the delivery device having a partially sheathed configuration, a fully sheathed delivery configuration, and a deployed configuration; and
a sheathing mechanism to crimp the implantable device and transition the delivery device from the partially sheathed configuration to the fully sheathed delivery configuration to sheathe the implantable device.

Abstract
Systems and methods are disclosed for delivering a stent to a lumen internal to a body of a patient and for sheathing a stent just prior to an insertion procedure. One embodiment comprises a delivery device having a partially sheathed configuration, a fully sheathed delivery configuration, and a deployed configuration. A panchor (combination pusher and anchor) is configured to engage and limit proximal and distal movement of the implantable device. An outer sheath surrounds a distal portion of an inner member and retains the implantable device near the distal end. The outer sheath is slidably moveable relative to the inner member to deploy the implantable device. Proximal movement of a trigger results in movement of the outer sheath to deploy the implantable device. A sheathing mechanism is configured to crimp and fully sheathe the implantable device prior to a deployment procedure.

17. A delivery system for sheathing a stent and deploying the stent within a body of a patient, the delivery system comprising:
-
a crimpable stent formed of a shape memory material; a delivery device to position and deploy the stent within the body, the delivery device having a tubular member configured to receive and house the stent in a crimped state for delivery to a target location within the body of the patient, the delivery device having a partially sheathed configuration, a fully sheathed delivery configuration, and a deployed configuration; and a sheathing mechanism configured to crimp and sheathe the stent as the delivery device transitions from the partially sheathed configuration to the fully sheathed delivery configuration. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A method for deploying an implantable device at a target location within a body of a patient, the method comprising:
-
positioning a sheathing mechanism at a distal region of a tubular member of a delivery device, wherein the delivery device is in a partially sheathed configuration having an implantable device partially unsheathed and partially sheathed at a distal end of the tubular member; grasping with a first hand the sheathing mechanism; grasping with a second hand a grip on the delivery device; advancing the sheathing mechanism in a distal direction with the first hand, and away from the second hand grasping the delivery device, while restraining distal movement of the grip of the delivery device, thereby moving the sheathing mechanism distally relative to the implantable device and over the implantable device and causing the sheathing mechanism to translate axial distal movement along the tubular member into radial force that compresses and thereby crimps the implantable device and to move the distal region of an outer sheath of the tubular member of the delivery device over the crimped implantable device to fully sheathe the implantable device; positioning the distal region of the tubular member of the delivery device with the crimped and sheathed implantable device within the body of the patient at a target location; and deploying the implantable device from the delivery device at the target location. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
