  • Methods for limiting the movement of material introduced between layers of spinal tissue
    Patent number: 7670375
    Abstract: Methods for limiting the movement of flowable material introduced into or between tissue layers of the human spine. The method can include inserting a member between tissue layers of the human spine. The member has a first configuration for insertion of the elongated member between tissue layers. The shape of the member is changed into a second configuration that defines a barrier that limits or directs the movement of flowable material. Flowable material is introduced to a selected location between the tissue layers and the barrier acts to limit or direct the movement of the flowable material.

  • Methods of distracting tissue layers of the human spine
    Patent number: 7670374
    Abstract: Methods of separating and/or supporting layers of tissue in the human spine. Such methods generally comprise inserting at least a distal end portion of a guide member between layers of tissue in the human spine wherein the distal end portion defines a predetermined shape. A distraction device is advanced over at least the distal end portion of the guide member so that the distraction device substantially assumes the predetermined shape of the distal end portion of the guide member to form a support structure between the tissue layers that separates and/or supports the tissue layers.

  • Disc space sizing devices
    Patent number: 9955961
    Abstract: Devices are provided for measuring and/or adjusting the distance between two opposing surfaces of a work space, such as two vertebral bodies separated by a disc space. A sizing device may include at least one distraction member, an actuator, and an actuator controller. The actuator controller is movable to move the actuator, with movement of the actuator changing the height dimension of the distraction member. The amount of movement of the actuator controller is generally linearly related to the change of the height dimension of the distraction member throughout the entire range of motion of the actuator controller. The amount of expansion force applied by the distraction member is also generally linearly related to the amount of movement of the actuator controller.

  • CATHETER-BASED TISSUE REMODELING DEVICES AND METHODS
    Publication number: 20090312598
    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.

  • Devices And Methods For Treating Bone Tissue
    Publication number: 20120330314
    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.
