  • Devices and methods for treating bone tissue
    Patent number: 9314252
    Abstract: The present disclosure relates to devices and methods for creating channels within bone. One method for treating bone generally includes traversing an elongated member through cancellous bone of a vertebral body along a first generally non-linear path and then retracting the elongated member, thereby leaving a generally non-linear channel. The elongated member then is traversed through the cancellous bone along a second generally non-linear path, which second path does not completely coincide with the first path and then retracted along the second generally nonlinear path, thereby leaving a second generally non-linear channel. Optionally, bone filler material is deployed into the channels.

  • Catheter-based tissue remodeling devices and methods
    Patent number: 8391996
    Abstract: Devices and methods utilizing a catheter to remodel soft tissue of a patient and, in a preferred embodiment, to reduce the volume of the left ventricle of a heart. In some embodiments, one or more sutures are passed through a wall of the ventricle. The ends of the one suture and, more preferably, the multiples sutures are drawn together to draw tissue portions towards one another. In some embodiments, a tissue remodeling clip is implanted into a wall of the ventricle. Ends of the clip are resiliently biased to move relative to one another to draw tissue portions towards one another. In some embodiments, a tissue remodeling anchor includes a base and a plurality of legs attached to the base. The legs of the tissue anchor are implanted into a wall of the ventricle and moved toward one another to draw tissue portions toward one another.

  • Catheter-based tissue remodeling devices and methods
    Patent number: 8333777
    Abstract: Methods and systems for closing an opening or defect in tissue, closing a lumen or tubular structure, cinching or remodeling a cavity or repairing a valve preferably utilizing a purse string or elastic device. The preferred devices and methods are directed toward catheter-based percutaneous, transvascular techniques used to facilitate placement of the devices within lumens, such as blood vessels, or on or within the heart to perform structural defect repair, such as valvular or ventricular remodeling. In some methods, the catheter is positioned within the right ventricle, wherein the myocardial wall or left ventricle may be accessed through the septal wall to position a device configured to permit reshaping of the ventricle. The device may include a line or a plurality of anchors interconnected by a line. In one arrangement, the line is a coiled member.

  • Spinal fusion implants and devices and methods for deploying such implants
    Patent number: 10231843
    Abstract: Methods and apparatus are disclosed for distracting tissue. The devices and methods may include insertion of first and second elongated members into the space between two tissue layers, with an augmenting elongated member inserted therebetween to form a distraction device between the tissues to be distracted. The distraction device defines a generally annular configuration, with a locking member secured to one of the elongated members at a plurality of locations to maintain the distraction device in the generally annular configuration. The augmenting elongated member may be shorter than the first and second elongated members such that a window is defined between the proximal and distal ends of the augmenting elongated member when the distraction device and the first and second elongated members are in the generally annular configuration. Bone graft material or bone filler may be introduced into the interior of the distraction device through the window.

  • Minimal impact access system to disc space
    Patent number: 10758286
    Abstract: Methods and apparatus for accessing and repairing a vertebral disc include a pad with a central cut-out mounted to the skin of a patient or, alternatively, a pedicle-mounted support. An incision is made and then a corridor is created using an elongated guide and a series of dilating tubes. An access to the disc space is created through the superior articular process and the facet joint using the corridor defined by the dilating tubes. Nucleus material is removed from the disc space and the vertebral endplates are prepared. The disc space may be sized to select a suitable implant, which is advanced through the corridor and into the disc space following discectomy and endplate preparation. Bone graft material may be inserted into the disc space following installation of the implant and then posterior rigid fixation may be achieved using percutaneous pedicle screws, followed by closure of the site.
