  • Patent number: 10548729
    Abstract: An implant structure includes a contracting mechanism, including a rotatable structure for contracting the implant structure, and a locking mechanism. A rotation tool is configured to engage and rotate the rotatable structure. A longitudinal guide member is removably coupled to the contracting mechanism, configured to guide the rotation tool to the rotatable structure, and includes a distal force applicator. The rotation tool is axially moveable with respect to the guide member. The contracting mechanism is arranged such that the locking mechanism is (a) unlocked when the guide member is coupled to the contracting mechanism in a first state, thereby allowing the rotatable structure to rotate, and (b) locked when (i) the guide member is coupled to the contracting mechanism in a second state, thereby restricting the rotation of the rotatable structure, and (ii) the guide member is not coupled to the contracting mechanism, thereby restricting the rotation of the rotatable structure.

  • Patent number: 10195026
    Abstract: Disclosed herein are prosthetic devices and related methods for implantation at the native mitral valve of the heart by drawing an atrial portion and a ventricular portion toward each other from opposite sides of the native mitral valve, clamping the native mitral valve therebetween. One or more retention members passing through the mitral valve orifice or through a puncture in the native valve anatomy can couple the atrial and ventricular members together and keep them anchored onto the native mitral valve anatomy. The atrial portion can seat against the atrial side of the mitral annulus while the ventricular portion can include hooks and/or a sub-annular ring that engage and capture the native mitral valve apparatus to provide anchorage. The described technology can avoid the need to use sutures to anchor a prosthetic device at the mitral valve region.

    Abstract: Devices and methods are described for treating a mitral valve defect. The device described includes features that allow the device to conform to the actual pathology of the valve, rather than attempting to replicate a healthy valve (which the patient does not have). In this way, the device allows the patient's actual value to work as well as possible, given the valve's diseased condition. The actual pathology of the valve is accommodated by providing for multiple dimensions of adjustability of the device, including adjustability of the size (e.g., diameter) of the device as well as adjustability of the elevation or inclination of one portion of the device (e.g., the portion supporting the posterior leaflet) with respect to another portion of the device.

  • Patent number: 9566178
    Abstract: Sealable and repositionable implant devices are provided with features that increase the ability of implants such as endovascular grafts and valves to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and/or with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes an implant body and a selectively adjustable assembly attached to the implant body, the assembly having adjustable elements and being operable to cause a configuration change in a portion of the implant body and, thereby, permit implantation of the implant body within an anatomic orifice to effect a seal therein under normal physiological conditions.

  • Patent number: 9498330
    Abstract: A method for reducing regurgitation in a mitral valve using a blood flow controlling apparatus. The blood flow controlling apparatus comprises a leaflet coaptation member, a connecting member, and an anchor suitable for anchoring the apparatus to the interventricular septum. The leaflet coaptation member coapts with the native mitral valve leaflets during systole when disposed therebetween, thereby reducing mitral valve regurgitation. During diastole, the native leaflets release coaptation with the leaflet coaptation member, permitting blood flow from the left atrium into the left ventricle.
