摘要： An implantable prosthetic device includes a spacer member configured to be disposed between leaflets of a native heart valve that is located between a first chamber and a second chamber of the heart. The prosthetic device further includes a plurality of anchor members coupled to the spacer member and configured to capture the leaflets between respective anchor members and the spacer member such that the prosthetic device is retained between the leaflets. The spacer member is configured to provide a flow path through the prosthetic device between the first chamber and the second chamber when the leaflets are captured between the anchor members and the spacer member such that blood can flow regurgitatively from the second chamber to the first chamber through the spacer member.

摘要： 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.

摘要： An exemplary valve repair system for repairing a native valve of a patient during a non-open-heart procedure includes a delivery device and a valve repair device. The delivery device includes a catheter, an actuation shaft, and a coupler. The valve repair device is configured to be delivered through the catheter. The valve repair device is configured to attach to a native valve of a patient. The valve repair device includes a coaption element having a first end portion and a second end portion, a proximal collar attached to the first end portion of the coaption element, first and second paddles connected to the coaption element, and a distal collar connected to the first and second paddles. The coupler is releasably connected to the proximal collar. The actuation shaft extends through the coupler, the proximal collar, and the coaption element. The actuation shaft is releasably connected to the distal collar.

摘要： An implantable prosthetic device includes a plurality of anchor members, a plurality of clasps, and a cover. The plurality of clasps are configured to capture the leaflets to secure the leaflets to the anchor members. The cover is disposed over the plurality of anchor members. The cover can also be disposed over the clasps and a spacer member. A portion of the cover can be covered by a coupler. One or more extensions of a coupling collar can extend through the cover.

摘要： An apparatus for repairing a heart valve can comprises a leaflet-plicating mechanism configured to plicate a leaflet of a heart valve and a helical needle comprising a plurality of coils. The needle can be configured to implant a suture to extend helically through plicated tissue of the heart valve. The leaflet-plicating mechanism can comprise first and second leaflet-capture arms, which can be configured to move toward and away from each other between an open position and closed position. The leaflet-capture arms can be configured to plicate the leaflet as the leaflet-capture arms are moved from the open position to the closed position.
