Abstract
An implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood. The coaption element can be connected to leaflets of the native valve by the anchor.
Claims21
A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
- a single strip of material;
- a coaption element comprising two or more folded layers of the single strip of material;
- and
- a pair of paddles comprising a portion of the single strip of material and connected to the coaption element, wherein the paddles are movable between an open position and a closed position;
- wherein the paddles are configured to attach to the native valve of the patient;
- and
- wherein the strip of material extends from a beginning in the paddle portion to an end in the paddle portion, and wherein the paddles comprise an inner paddle portion and an outer paddle portion, and wherein the beginning and end of the strip of material are located in the inner paddle portions.
The valve repair device of 1 wherein the paddles are disposed over an extension member.
A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
- a single strip of material;
- a coaption element comprising two or more folded layers of the single strip of material;
- a pair of paddles comprising a portion of the single strip of material and connected to the coaption element, wherein the paddles are movable between an open position and a closed position;
- wherein the paddles are configured to attach to the native valve of the patient;
- a clasp associated with each paddle of the pair of paddles, each clasp having at least one barb, a barb support portion, and a moveable arm.
A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
- a single strip of material;
- a coaption element comprising two or more folded layers of the single strip of material;
- a pair of extension members, each extension member having attachment portions;
- a pair of paddles comprising a portion of the single strip of material, wherein the paddles are movable between an open position and a closed position, are disposed over the extension member, and are configured to attach to the native valve of the patient;
- a cap attached to the paddles, wherein movement of the cap toward the coaption element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaption element causes the pair of paddles to move to the open position;
- a retention body having a locking aperture for receiving the attachment portions of the extension members;
- a retaining nut configured to insert into the locking aperture;
- and
- a retaining bolt for securing the retaining nut within the locking aperture.
