摘要： A prosthetic device for sealing a native heart valves to prevent or reduce regurgitation comprises a spacer having one or more anchors. The spacer may also have atrial support structures, ventricular support structures, or both atrial and ventricular support structures In some cases, the spacer has anchors that attach to the leaflets as well as atrial and ventricular support. In some cases, the spacer straddles the annulus and is located by anchors, and in some cases the support structures can be implanted within the native heart valve. In some cases, the prosthetic device reduces the annulus diameter when implanted within the native heart vasculature. In some cases, the prosthetic device cinches the annulus when implanted within the native heart vasculature.

摘要： The present disclosure relates generally to systems, devices, and methods for supporting, stabilizing, and/or positioning a medical device, such as a transcatheter medical device. The stabilizer allows for control of degrees of freedom from no movement to free movement to selective movements, to substantially translation only movement and/or to substantially rotational only movement of the medical device. The patent describes pure mechanical embodiment as well as smart embodiments that can synergistically sense, actuate and/or transmit data between the stabilizer, medical device and control or display system to operate and/or deploy the device/therapy.

摘要： A clip for immobilizing leaflets of a cardiac or venous valve includes a hub having a pair of tangle resistant spring-biased outer arms coupled to an inferior end of the hub and a pair of tangle resistant spring-biased inner arms adjacent to the outer arms and coupled to a superior end of the hub. A delivery catheter with stiffening members configured to position the valve clip adjacent a target valve while the outer and inner arms are biased in an opened position relative to each other. The delivery catheter or clip comprises of sutures that assist in bail out. After the valve leaflets are located between the opened outer and inner arms, the biasing forces may be released to allow the clip to self-close the clip over the valve leaflets, to atraumatically and effectively cinch and coapt the leaflets.

摘要： A clip for immobilizing leaflets of a cardiac or venous valve includes a hub having a pair of tangle resistant spring-biased outer arms coupled to an inferior end of the hub. A pair of tangle-resistant spring-biased inner arms lies adjacent to the outer arms and is coupled to a superior end of the hub. The clip may incorporate adjustable spacers and retrievable post implantation. A delivery catheter is used to position the valve clip adjacent a target valve while the outer and inner arms are biased in an opened position relative to each other. After the valve leaflets are located between the opened outer and inner arms, the biasing forces may be released to allow the clip to self-close over the valve leaflets.

摘要： Impression devices are provided for making an impression of a desired feature. The impression devices include: a flexible bladder having a cavity formed therein, the flexible bladder being capable of conforming to the details of the desired feature; a rheological material, such as a magnetorheological fluid, disposed in the cavity of the flexible bladder; and an activator for applying an external stimulus to the rheological material to change the state of the rheological material and thereby capture an impression of the desired feature.

摘要： An apparatus for sampling tissue includes a tissue engaging member for engaging and retaining a sample of a tissue structure, and a cutter surrounding the tissue engaging member. The tissue engaging member and cutter are both operative to translate longitudinally with respect to one another, and a mechanism prevents the cutter from moving distally, the mechanism being released and the cutter freed to move distally when the tissue engaging member is in a predetermined position, preferably distal of the cutter. Thereby, out of sequence operation, e.g., premature cutting of the tissue before the tissue engaging member is in position, is prevented.
