摘要:
An augmentation instrument for attaching a retaining device to a vertebral endplate comprises a drive housing having a distal end portion, a drive mechanism extending through the drive housing and including a flexible shaft portion, and an attachment mechanism at the distal end portion of the drive housing. The attachment mechanism is adapted for coupling to the retaining device.
摘要:
Systems and methods for repairing annulus defects include at least one blocking member positionable in or adjacent to the annulus defect, and at least one anchor for securing the blocking member to adjacent tissue recessed into the adjacent vertebrae. The blocking member extends at least partially across the annulus defect for repair of the defect and/or retention of nucleus material, one or more implants, bio-compatible materials or device, and/or other objects positioned in the disc space. Instruments are provided to facilitate preparation of the implantation site of the annulus repair system

Systems and methods for repairing annulus defects include at least one blocking member positionable in or adjacent to the annulus defect, at least one attachment portion for securing the blocking member to adjacent tissue, and instruments for placing and engaging the blocking member in and/or adjacent to the annulus defect. The blocking member extends at least partially across the annulus defect for repair of the defect and/or retention of nucleus material, one or more implants, bio-compatible materials or device, and/or other objects positioned in the disc space.
摘要:
Methods and devices are provided for the explantation of spinal implants. A cutting tool may be extended into the spinal implant. The spinal implant may be cut into pieces and the pieces removed.

摘要:
Devices and methods for aggressively and continuously cutting and removing anatomical tissue. The device may comprise elongated outer and inner tubes having respective proximal and distal ends. The inner tube is moveably received in the elongated inner. A cutting assembly is rotatably received in the elongated inner tube. The device may also comprise a handle arm attached near the proximal end of the outer tube, and a trigger arm attached near the proximal end of the inner tube. A movable jaw is pivotally attached near the distal end of the outer or inner tube, the movable jaw being urged towards the cutting blade assembly as the trigger arm is actuated.
摘要:
A perianal support device is provided that is configured to inhibit the formation and/or progression of tissue damage in the perianal region of the body. A method is provided to apply the perianal support device to patients during childbirth to inhibit the formation and/or progression of tissue damage in the perianal region of the body.

摘要:
The invention provides devices and related methods and composition useful for diagnosis and monitoring the pain generator(s) of axial pain with or without radiculopathy and methods for screening test compounds potentially useful for treating axial pain with or without radiculopathy. Alternatively, degenerated discs can be monitored and treated before occurrence of a pathological pain condition. Pain markers and markers of degenerating disc include markers of neuronal, vascular, immune and matrix elements.
摘要:
Devices and methods for spinal stabilization include first and second anchor assemblies engageable to respective ones of first and second vertebrae and a connecting element engageable to the first and second anchor assemblies. The connecting element includes opposite first and second end members and a bumper assembly between the end members that flexibly connects the end members so the connecting element can provide dynamic stabilization of the spinal column when engaged to the anchor assemblies.
