IMPLANTABLE DEVICE DEPLOYMENT APPARATUS
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 panchor disposed within the tubular member and configured to engage a proximal portion of the implantable device in the partially sheathed configuration and the fully sheathed delivery configuration, wherein the panchor provides a push surface and an anchor, the push surface configured to abut the implantable device and limit proximal movement of the implantable device relative to the panchor during deployment as the delivery device transitions from the fully sheathed delivery configuration to the deployed configuration and the anchor configured to engage the implantable device and limit distal movement of the implantable device relative to the panchor during sheathing as the delivery device transitions from the partially sheathed configuration to the fully sheathed delivery configuration.

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.

16. A panchor deployment apparatus configured to be disposed in a tubular member of a delivery device for sheathing a crimpable implantable device and deploying the implantable device within a body of a patient, the panchor deployment apparatus comprising:
-
a base segment having a cylindrical shape and configured to be disposed within the tubular member of the delivery device and at least partially within a lumen of the implantable device; a push surface disposed orthogonal to a surface of the base segment and configured to abut a proximal end of the implantable device to limit proximal movement of the implantable device relative to the panchor deployment apparatus during deployment as the delivery device transitions from the fully sheathed delivery configuration to the deployed configuration; and an anchor configured to engage the implantable device and limit distal movement of the implantable device relative to the panchor during sheathing as the delivery device transitions from the partially sheathed configuration to the fully sheathed delivery configuration. - View Dependent Claims (17, 18, 19, 20)
