  • Patent number: 10182810
    Abstract: Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.

  • Patent number: 10178989
    Abstract: A surgical suture system, tissue restraint/suture capture and tissue anchor for tissue repair and reattachment of torn tissue to a tissue substrate, medical, veterinary or dental prosthesis or medical implant. The system includes a plurality of tissue restraints/suture captures which each include a central locking aperture sized and configured to receive a beaded suture member passed therethrough which minimizes longitudinal tensioning and/or restraining movement, the “GO” force, of a beaded suture member in the forwardly direction through the locking apertures for suture tightening and which maximizes “NO-GO” force to pull the suture in the reverse direction. Uniquely configured tissue anchors and other medically implantable devices securely receive one of the tissue restraints/suture captures for tensioning of a suture member between tissue and the tissue anchor.

  • Patent number: 10149752
    Abstract: Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation. To that end, embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein.

  • Patent number: 10137228
    Abstract: An apparatus, system, and method for treating an incisional wound having incisional walls is disclosed. The apparatus includes a conduit having a first end for receiving reduced pressure and a second end. The apparatus further includes a scaffold. The scaffold has opposing surfaces for positioning adjacent the incisional walls and is fluidly coupled to the second end of the conduit for receiving the reduced pressure. The scaffold is generally elongated in shape and has a thickness between the opposing surfaces that is sufficiently thin for positioning within the incisional wound. The apparatus further includes an internal manifold that has a primary flow channel extending generally longitudinally within the scaffold and between the opposing surfaces of the scaffold. The internal manifold is fluidly coupled to the second end of the conduit. The application of the reduced pressure through the scaffold and the internal manifold induces tissue apposition between the incisional walls.

  • Patent number: 10130464
    Abstract: Embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native leaflets of a valve. A locking member is used to couple both ends of the support member, forming a support band. An expandable prosthetic heart valve is delivered into the native heart valve and expanded while the expandable prosthetic valve is at least partially within the support band, thereby causing one or more of the native leaflets of the native heart valve to be frictionally secured between the support band and the expanded prosthetic heart valve.
