DELIVERY SYSTEMS FOR A MEDICAL DEVICE AND RELATED METHODS
First Claim
1. A delivery system for a medical device, comprising:
- a handle;
a handle extension coupled with the handle,a sleeve disposed about the handle extension;
a catheter coupled to the sleeve; and
an actuator associated with the sleeve;
wherein the sleeve is moveable from a first position to an second position to partially unsheathe a medical device from a distal tip of the catheter, and wherein, upon actuation of the actuator, the sleeve is moveable from the second position to a third position to fully unsheathe a medical device from the distal tip of the catheter.

Abstract
Delivery systems for a medical device and related methods are provided. In one embodiment the delivery system includes a handle, a handle extension, and a sleeve. The handle extension extends from the handle and includes at least one channel defined therein along a longitudinal length of the handle extension. The handle extension also includes an abutment surface positioned in the at least one channel. The sleeve is disposed around the handle extension and is coupled to a catheter. The sleeve also includes a biased actuator configured to be moved between at least two actuator positions. The sleeve is moveable from a distal position to an intermediate position where it is stopped via the abutment surface to partially unsheathe a medical device from the catheter. The actuator can then be manually actuated to enable displacement of the sleeve to a proximal position to fully unsheathe the medical device from the catheter.

17. A delivery system for a medical device, comprising:
-
a handle; a handle extension coupled with the handle, the handle extension including at least one channel defined therein and along a longitudinal length of the handle extension and at least one abutment surface associated with the at least one channel; a sleeve disposed about the handle extension; a catheter coupled to the sleeve; and an actuator associated with the sleeve and configured to be displaced between at least a first actuator position and a second actuator position, the actuator having at least one projection; wherein the sleeve is moveable from a first position to a second position, wherein the at least one projection of the actuator abuts the at least one abutment surface and wherein the catheter is displaced to partially unsheathe a medical device from a distal tip of the catheter. - View Dependent Claims (18)

19. A method of delivering a medical device, the method comprising:
-
housing a medical device within a tip portion of a catheter; positioning the tip portion of the catheter at a desired location; partially unsheathing the medical device by displacing a sleeve coupled with the catheter from a first position relative to a handle to a second position relative to the handle wherein, at the second position, an actuating assembly engages an abutment surface; displacing the actuator to disengage the actuator from the abutment surface; and displacing the sleeve and catheter to a third position relative to the handle to fully unsheathe the medical device. - View Dependent Claims (20, 21, 22, 23, 24)
