Abstract: An implantable prosthetic device can include a spacer member, a plurality of anchors, and a plurality of clasps. The spacer member can be configured to be disposed between native leaflets of a heart. The anchors can be coupled to the spacer member and configured to secure the native leaflets against the spacer member. The clasps can be coupled to a respective anchor and configured to secure the native leaflets to the anchors. The clasps can be independently movable between an open configuration and a closed configuration.

Abstract: An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. The device can be deployed from a delivery system including one or more lines which can be decoupled from the device by energizing. The device can include contoured clasps which approximate the shape of the native valve when the clasps are in the closed position. The device can include a coaptation element with body portion including a plurality of struts and openings defining a lattice structure. One or more surfaces of one or more components of the device can be coated to improve the visibility of the device during deployment and implantation.

Abstract: A method and system for implanting and repositioning an implantable device for a native valve of a patient's heart includes a delivery catheter, a collar, a coupler, and an actuation element. The actuation element extends through the delivery catheter and attaches to the device to open the device. The collar is connected to the device and the coupler is connected to the delivery catheter. The collar and coupler are tied together via one or more coupling tethers which can be used to reengage the device after an initial deployment.
