Annuloplasty Device Patents (Class 623/2.36)
  • Patent number: 8475524
    Abstract: During a minimally invasive deployment of a mitral valvuloplasty device into the coronary sinus near realtime tracking of the device is monitored to determine whether the device is compressing the left circumflex coronary artery or is likely to do so. In one embodiment of the invention, one or more position sensors are included in the catheter that is used to deploy the constricting implant and or in the implant itself. The position of the device is determined during deployment, and compared to the location of the left circumflex coronary artery, which may be determined by mapping relative to a pre-acquired image or by simultaneous intracardiac ultrasound imaging.

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.

  • Patent number: 8262725
    Abstract: Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band having an elongate and arcuate body. The elongate and arcuate body has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is displaced from the plane containing the first end and the second end. The transvalvular band is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets and the central portion is displaced towards the left ventricle relative to the first anchoring portion and the second anchoring portion. The ventricular direction displacement moves coaption to an earlier point in the cardiac cycle.

  • Publication number: 20120215304
    Abstract: Annuloplasty rings optimally sized to take into account more of the common degenerative valve pathologies. Each ring has a structural ring body with a shape that complies with predicted shapes of degenerative valvular diseases. The predicted shapes are obtained through careful echocardiographic and intraoperative measurements, and often differ for different annulus orifice sizes. For instance, in mitral rings the larger rings have larger minor axis and oblique axis dimensions relative to their major axis dimensions, and are more circular as opposed to D-shaped. The rings may also be three-dimensional and the relative heights around the rings may change for different sized rings. A mitral ring may have a higher anterior saddle relative to a posterior saddle, with the relative heights varying across the ring sizes. The ring may have varying flexibility around the ring periphery which also changes for different ring sizes.

  • Patent number: 8236050
    Abstract: Methods of implanting an annuloplasty ring to correct maladies of the mitral annulus that not only reshapes the annulus but also reconfigures the adjacent left ventricular muscle wall. The ring may be continuous and is made of a relatively rigid material, such as Stellite. The ring has a generally oval shape that is three-dimensional at least on the posterior side. A posterior portion of the ring rises or bows upward from adjacent sides to pull the posterior aspect of the native annulus farther up than its original, healthy shape. In doing so, the ring also pulls the ventricular wall upward which helps mitigate some of the effects of congestive heart failure. Further, one or both of the posterior and anterior portions of the ring may also bow inward.

  • Publication number: 20120197388
    Abstract: Implants, implant systems, and methods for treatment of mitral valve regurgitation and other valve diseases generally include a coaptation assist body which remains within the blood flow path as the leaflets of the valve move, the valve bodies often being relatively thin, elongate (along the blood flow path), and/or conformable structures which extend laterally from commissure to commissure, allowing the native leaflets to engage and seal against the large, opposed surfaces on either side of the valve body during the heart cycle phase when the ventricle contracts to empty that chamber of blood, and allows blood to pass around the valve body so that blood flows from the atrium to the ventricle during the filling phase of the heart cycle. Separate deployment of independent anchors near each of the commissures may facilitate positioning and support of an exemplary triangular valve body, with a third anchor being deployed in the ventricle.

  • Patent number: 8231671
    Abstract: A mitral cerclage annuloplasty apparatus comprises a tissue protective device and a knot delivery device. The tissue protective device comprises a first protective tube and a second protective tube. The knot delivery device comprises a tube wherein a loose knot is looped around its distal end through a hole and wherein tight knot is formed when the distal end of the tube is cut open. Alternatively, the knot delivery device comprises an inner tube and outer tube. The inner tube is insertable and rotatable inside the outer tube. When the tubes are in a closed position by rotating either the outer tube or the inner tube, a hole is created near its distal end. When the tubes are in open position by rotating either the outer tube or the inner tube, the hole joins the opening of the outer tube and lengthens.

    Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.
