  • Intracardiac device to correct mitral regurgitation
    Patent number: 10842626
    Abstract: A device structured to suppress mitral regurgitation by restricting prolapse of a mitral valve leaflet and including a base correspondingly dimensioned to the mitral valve and including a central portion, structured to allow blood flow there through and a peripheral portion or ring connected to the central portion in substantially surrounding relation thereto. An operative position of the base includes the central portion disposed in overlying, movement restricting relation to at least one of the valve leaflets and the ring concurrently anchored adjacent or directly to the native annulus of the mitral valve. The physical characteristics of the base facilitate its movement with and conformance to the mitral valve during diastole and systole cycles of the heart.

  • Systems and methods of treating malacia by local delivery of hydrogel to augment tissue
    Patent number: 10842969
    Abstract: Systems, devices, and methods for maintaining patency in a bronchus of a patient are presented. A catheter is positioned within the bronchus. A target region of one or more of a bronchial wall, submucosa, media, and adventitia is punctured with an injection needle disposed on a distal end of the catheter. Such puncturing is achieved by expanding a balloon disposed on the distal end of the catheter. The balloon may be comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. Through the injection needle, an amount of one or more crosslinking agents is delivered to the target region. The delivered amount is effective to provide structural support for the bronchial wall, substituting for the bronchial cartilage thereby treating bronchomalacia.

  • Mitral repair and replacement devices and methods
    Patent number: 10653519
    Abstract: An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor with a central turn that reduces in size upon implantation is used to approximate the amount of reduction in the size and the reshaping of the native mitral annulus to reduce valve leakage. A clip can be further applied to the native valve leaflets to reduce the size of the native mitral annulus and leakage therethrough. A prosthetic heart valve can be implanted in the coiled anchor to replace and further improve functionality of the valve. In some cases, the prosthetic valve can be implanted in a clipped valve, where the clip is detached from one of the native valve leaflets to provide space for the prosthetic valve to expand.

  • Patient-specific craniofacial implants
    Patent number: 10639158
    Abstract: Disclosed herein are patient-specific facial or craniofacial implants structured for filling bone voids in the cranium and face as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance of face and skull. Pterional or temporal voids or defects generally result from a chronic skull or lateral facial deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle atrophy occurs in the pterion or temporal face, temporal hollowing deformity generally results where there would be soft tissue but for the atrophy. The patient-specific temporal implants with dual-purpose herein are configured to have an augmented region adjacent the temporal region of the face and cranium in order to prevent and/or correct any such temporal hollowing deformity.
