Opposing disk device for grasping cardiac valve tissue
First Claim
1. A method for repairing a targeted cardiac valve, the method comprising:
- positioning a repair device at a targeted cardiac valve, the repair device being moveable between a collapsed configuration and an expanded configuration, the repair device including;
a proximal disk element;
a distal disk element spaced apart from the proximal disk element so as to define a grasping space therebetween for grasping cardiac valve tissue; and
a neck section joining the proximal disk element and the distal disk element, the neck section having a diameter that is smaller than a diameter of the proximal disk element and the distal disk element;
wherein the proximal disk element, the distal disk element, and the neck section are integrally formed as a self-expanding structuredeploying the distal disk element on a first side of targeted cardiac valve tissue to move the distal disk element from the collapsed configuration to the expanded configuration; and
deploying the proximal disk element on a second side of the targeted cardiac valve tissue to move the proximal disk element from the collapsed configuration to the expanded configuration so as to grasp the cardiac valve tissue between the deployed distal disk element and the deployed proximal disk element.

Abstract
The present disclosure relates to repair devices and methods for repair of regurgitant tricuspid valves. A repair method includes positioning a repair device at a tricuspid valve in a collapsed configuration. The repair device includes a proximal disk and a distal disk joined by a neck section. The distal disk is deployed by passing it from the collapsed state to an expanded configuration on a first side of the tricuspid valve. The proximal disk is then deployed by passing it from the collapsed state to an expanded configuration on a second side of the tricuspid valve so as to grasp all three tricuspid valve leaflets between the deployed distal disk and the deployed proximal disk.

16. An interventional system configured for repair of a regurgitant tricuspid valve, the repair system comprising:
-
a delivery system, including; a sheath; a delivery catheter disposed within the sheath so as to be translatable within the sheath, the delivery catheter including a connection element disposed at a distal end of the delivery catheter; and an interventional device, including; a connection element configured to engage with the connection element of the delivery catheter to detachably couple the interventional device to the delivery catheter; a proximal disk element movable between a collapsed configuration and an expanded configuration; a distal disk element moveable between a collapsed configuration and an expanded configuration, the distal disk element being spaced apart from the proximal disk so as to define a grasping space therebetween for grasping tricuspid valve leaflets when the proximal disk element and the distal disk element are in expanded configurations and are deployed at a tricuspid valve; a neck section joining the proximal disk element and the distal disk element, the neck section having a diameter that is smaller than a diameter of the proximal disk element and the distal disk element; wherein the proximal disk element, the distal disk element, and the neck section are integrally formed as a self-expanding structure, wherein the sheath is configured to be retractable relative to the delivery catheter to expose the interventional device and enable the distal disk element and the proximal disk element to move toward the expanded configuration. - View Dependent Claims (17, 18, 19)
