Delivery catheter handle and methods of use
First Claim
1. A medical delivery system, comprising:
- a housing;
a delivery device disposed at least partially within the housing;
a lock configured to releasably secure the delivery device relative to the housing when in a locked configuration, and to allow translation of the delivery device within the housing when in an unlocked configuration, the lock disposed on a portion of the delivery device and selectively contacts an outer surface of the portion of the delivery device to selectively lock both translation and rotation of the portion, the lock is configured as a spring clamp, the spring clamp having a diameter when in a relaxed configuration that is smaller than a diameter when in a stressed configuration;
a lock actuator configured to engage with the lock to move the lock from the locked configuration toward the unlocked configuration; and
a handle coupled to the lock actuator, the handle being configured to move the lock actuator to engage with the lock upon the handle being moved from a default position toward a depressed position;
a sleeve having a proximal end coupled to the housing; and
a catheter having a proximal end coupled to the delivery device, the catheter extending distally from the delivery device through a lumen of the sleeve;
wherein depression of the handle allows the delivery device to be translated within the housing so as to translate the catheter within the sleeve.

Abstract
Methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. A delivery device for delivering an implantable device to a target area includes a fluid management system for directing fluid and delivery device components to the target area. The delivery device includes a grip line assembly configured to control a gripper in the implantable device for grasping tissue at the target area. The delivery device includes a lock line assembly configured to control a locking mechanism in the implantable device to lock the implantable device in a desired orientation. The delivery device includes a deployment handle configured to provide staged deployment of the implantable device. A delivery assembly includes a housing and a delivery device partially housed within the housing and being adjustable using one-handed operation.

13. A medical delivery system, comprising:
-
a sleeve housing; an outer catheter housing; an outer catheter having a proximal end coupled to the outer catheter housing; a sleeve having a proximal end coupled to the sleeve housing, the sleeve extending distally from the sleeve housing through a lumen of the outer catheter; a delivery device disposed at least partially within the sleeve housing; a delivery catheter having a proximal end coupled to the delivery device, the delivery catheter extending distally from the delivery device through a lumen of the sleeve; a lock configured to releasably secure the delivery device relative to the sleeve housing when in a locked configuration, and to allow translation of the delivery device within the sleeve housing when in an unlocked configuration, the lock encircling a portion of the delivery device and selectively contacts an outer surface of the portion of the delivery device to selectively lock translation and rotation of the portion, the lock is configured as a spring clamp, the spring clamp having a diameter when in a relaxed configuration that is smaller than a diameter when in a stressed configuration; a lock actuator configured to engage with the lock to move the lock from the locked configuration toward the unlocked configuration; a handle coupled to the lock actuator, the handle being configured to move the lock actuator to engage with the lock upon the handle being moved from a default position toward a depressed position; and an implantable device coupled to a distal end of the delivery catheter and configured to be implantable at a target area; wherein depression of the handle allows the delivery device to be translated within the housing so as to translate the guide catheter within the sleeve and the outer catheter, enabling the implantable device to be translated relative to a target area. - View Dependent Claims (14, 15, 16)

17. A method of positioning a delivery catheter at a target area, the method comprising:
-
positioning a distal end of a sleeve at a target area, the sleeve having a proximal end coupled to a delivery assembly, the delivery assembly including; a housing coupled to the sleeve; a delivery device disposed at least partially within the housing; a lock configured to releasably secure the delivery device relative to the housing when in a locked configuration, and to allow translation of the delivery device within the housing when in an unlocked configuration, the lock disposed on a portion of the delivery device and selectively contacts an outer surface of the portion of the delivery device to selectively lock translation and rotation of the portion, the lock is configured as a spring clamp, the spring clamp having a diameter when in a relaxed configuration that is smaller than a diameter when in a stressed configuration; a lock actuator configured to engage with the lock to move the lock from the locked configuration toward the unlocked configuration; and a handle coupled to the lock actuator, the handle being configured to move the lock actuator to engage with the lock upon the handle being moved from a default position toward a depressed position; depressing the handle to allow the delivery device to be translated within the housing; and translating the delivery device within the housing so as to translate the catheter within the sleeve.
