  • Patent number: 12186191
    Abstract: An device for treating a native valve includes a sealing element and an anchoring element. The sealing element is made from a braided mesh material. The sealing element is dimensioned to be deployed in an annulus of a native valve of a heart at a position between native valve leaflets to contact the native valve leaflets during ventricular systole to create a seal to prevent regurgitation of blood from the left ventricle to the left atrium. The sealing element is configured to both be radially expanded and radially reduced while at the position between the native valve leaflets. The anchoring element is adapted for deployment in the heart, the anchoring element coupled to the sealing element and configured to support the sealing element at the desired position between native valve leaflets.

  • Patent number: 12023248
    Abstract: A coronary artery check valve includes a stent configured to attach to an inner wall of a coronary artery of a living subject, and a tapered helical coil coupled to the stent and configured to regulate blood flow in the coronary artery. The coronary artery check valve is configured to prevent retrograde flow of the coronary blood supply during diastole by closing during systole of the heart when the tapered helical coil compresses longitudinally, and opening when the tapered helical coil expands longitudinally to permit blood flow into the coronary artery when a coronary pressure of the living subject drops below diastolic blood pressure.

  • Patent number: 11470813
    Abstract: A centrifugal pump pet water fountain is provided which includes a bowl defined by a peripheral wall extending upwardly from a floor. The bowl is configured to hold water. The housing divides the basin into a drinking basin and an interior basin. The housing includes an upright sidewall extending from a floor and a cap. The housing also defines an elevated water reservoir with a spout. A rotating cone is positioned within the housing and driven by a motor. The cone has a water inlet and a top opening adjacent the cone top opening. During operation, the rotation of the cone forces water to climb the interior surface of the cone through centrifugal force, where the water is deposited within the reservoir and returned to the drinking basin through the spout.

  • Patent number: 11344415
    Abstract: An exemplary valve repair device for repairing a native valve of a patient includes: a coaption element formed from a strip of material; a pair of extension members; a pair of paddles formed from the strip of material and connected to the coaption element; and a cap attached to the paddles. 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. 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. The cap has a retention body for receiving attachment portions of the extension members, a retaining nut, and a retaining bolt for securing the retaining nut.
