  • Patent number: 11944540
    Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.

  • Patent number: 11925336
    Abstract: A system and method used to deliver a valve delivery system carrying a valve to a target valve annulus in the heart includes a cable percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, transseptally through the heart, to a femoral artery. The valve delivery system device is passed over an end of the cable at the arterial side and is secured to the cable.

  • Patent number: 11918460
    Abstract: Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.

  • Patent number: 11883295
    Abstract: A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and-error sizing methods.

  • Patent number: 11844665
    Abstract: A first part of an annuloplasty structure is anchored to an annulus of a valve of a heart by using a driver to screw a tissue-coupling element of a first anchor into a first site of the annulus, such that the tissue-coupling element enters cardiac tissue in a direction parallel to a central longitudinal axis of the driver through the distal end of the anchor driver. The same is subsequently done for second and third parts of the annuloplasty structure using second and third anchors at second and third sites of the annulus, mutatis mutandis. Between anchors, the driver is retracted out of the heart. Subsequently, the valve is treated by reducing a distance between the first site and the second site, and a distance between the second site and the third site, by tightening a flexible and elongate contracting member of the annuloplasty structure.

  • Patent number: 11793629
    Abstract: A device, a kit and a method are presented for permanently augmenting the pump function of the left heart. The basis for the presented innovation is an augmentation of the physiologically up and down movement of the mitral valve during each heart cycle. By means of catheter technique, minimal surgery, or open-heart surgery implants are inserted into the left ventricle, the mitral valve annulus, the left atrium and adjacent tissue in order to augment the natural up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling and the piston effect of the closed mitral valve when moving towards the apex of said heart in systole and/or away from said apex in diastole.

    Abstract: Systems for delivering prosthetic heart valve devices can include, for example, an elongated catheter body, a deliver capsule carried by the catheter body, and an expandable atraumatic member. The delivery capsule includes a platform and a housing having an outer wall and a proximal rim, and the platform is configured to be releasably coupled to a prosthetic heart valve device. The housing is configured to slide along the platform from a containment configuration to a deployment configuration. The expandable atraumatic member has an atraumatic surface and a peripheral portion. The atraumatic member has a compacted configuration and an expanded configuration in which the peripheral portion extends laterally outward over the proximal rim of the housing to protect tissue of the heart and the vasculature from potentially being damaged by the proximal rim of the housing as the delivery system is withdrawn in a proximal direction through the patient.

  • Patent number: 11759316
    Abstract: Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.
