Abstract: A loader and method for loading a transcatheter heart valve into a delivery sheath or catheter is described that is also configured to facilitate retrieval of the heart valve back through the delivery sheath while protecting the delivery sheath from damage. Another loader provides for easier crimping and loading of a THV into a delivery sheath or catheter from a storage jar or container. A method for crimping a THV facilitates easier end user preparation of the valve for implantation and reduces the likelihood of tissue deformation in the valve during storage. These devices and methods for deploying THVs simplify the valve replacement procedure.

Abstract: A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a surgical delivery instrument, a valve repair device, and a gripper control mechanism. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to be attached to a native valve of a patient. The valve repair device includes a pair of paddles, and at least four gripping members. The paddles are movable between an open position and a closed position, and the paddles and the at least four gripping members are configured to attach to the native valve of a patient. The gripper control mechanism is configured to independently move each of the at least four gripping members.

Abstract: A valve repair device for repairing a native valve of a patient includes a spacer element, a pair of paddles, and a pair of gripping members. The pair of paddles is coupled to the spacer element. The pair of gripping members is disposed between the pair of paddles. The paddles and the gripping members are configured to attach to leaflets of a heart valve. The spacer element extends past side edges of the gripping members, extends past side edges of the paddles, or extends past the side edges of both the gripping members and the paddles.

Abstract: A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a paddle and a gripping member. The paddle is movable between an open position and a closed position. The gripping member has a weakened portion and a barbed portion. The barbed portion is configured to secure the gripping member to valve tissue of the native valve of the patient. A gripper control mechanism is configured to move the gripping member between an open position and a closed position. The gripper control mechanism comprises a suture removably attached to the gripping member at a first connection point and a pushing member configured to engage the gripping member at a second connection point. The weakened portion is between the first and second connection points. The pushing member is configured to push on the gripping member and the suture is configured to pull on the gripping member to flex the weakened portion and pivot the barbed portion.

Abstract: A pair of paddles are moved laterally away from one another in an exemplary method of repairing a native valve of a patient during a non-open-heart procedure. After the paddles are moved laterally away from one another, first and second gripping members are moved from an open position to a closed position to grasp valve leaflets. The paddles are then moved laterally toward one another. A cam can be used to move the paddles away from one another.

Abstract: An exemplary recapturable valve repair system for repairing a native valve of a patient during a non-open heart procedure has a delivery device, a valve repair device, and a tethering line. The delivery device has a catheter and a coupler. The valve repair device is configured to be delivered through the catheter and attach to a native valve of a patient. The valve repair device includes a coaption element, a proximal collar, and first and second paddles. The first and second paddles are connected to the coaption element. The coupler is releasably connected to the proximal collar. The tethering line connects the valve repair device to the delivery device for recapturing the valve repair device.

Abstract: An exemplary valve repair device for repairing a valve of a patient has a paddle, and a clasp. The clasp has a fixed arm attached to the paddle and a moveable arm. The moveable arm includes barbs that are spaced apart from a connection between the moveable arm and the fixed arm. The moveable arm is movable between open and closed positions relative to the fixed arm. The moveable arm has a weakened portion between the barbs and the connection between the moveable arm and the fixed arm. Applying tension to the movable arm in a retraction direction stretches the moveable arm and moves the barbs in the retraction direction.

Abstract: A delivery system includes an elongate shaft, a handle, a first clasp control member, and a second clasp control member. The handle is connected to a proximal portion of the elongate shaft. The first and second clasp control members each extend into a distal portion of the elongate shaft, through at least a portion of the elongate shaft, out of the proximal portion of the elongate shaft, and through the handle. The first and second clasp control members have paths that include a first parallel portion in the elongate shaft where the first clasp control member and the second clasp control member are parallel, and a diverging portion that is proximal to the first parallel portion where the first clasp control member diverges from the second clasp control member.

Abstract: Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.
