  • Publication number: 20190167167
    Abstract: On-body analyte sensors may be designed for extended wear to provide ongoing measurement of physiological analyte levels. However, on-body analyte sensors may be susceptible to damage or dislodgment during wear due to routine interactions that occur with one's surroundings. Guard rings may be adapted to protect on-body analyte sensors from such interactions. Guard rings may comprise an annular body comprising an inner perimeter face, an outer perimeter face, a top edge, and a bottom face adapted for contacting a tissue surface. The inner perimeter face is shaped to circumferentially surround a sensor housing of an on-body analyte sensor. At least a portion of the outer perimeter face defines a chamfered surface extending between the top face and the bottom face. Adhesive pads or strips may further be engaged with the guard rings and aid in securing the guard rings to a surface, such as skin.

  • Patent number: 8894686
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

  • Patent number: 8641762
    Abstract: An implant system for implantation between adjacent spinous processes for the relief of pain associated with the spine. The implant has a series of spacers which may be inserted over a shaft located between adjacent spinous processes thus allowing the implant to be assembled in situ. The spacers may rotate on the shaft relative to the wings. To minimize trauma to the patient, each spacer has a tapered tissue expander to distract the opening between the spinous processes during assembly. The shaft is connected to a wing, and a second wing or deployable wing may be inserted over the shaft and locked into place.

  • Patent number: 8591546
    Abstract: A spinal implant adapted to be inserted into an interspinous space between adjacent spinous processes includes a proximal section, a central section, and a distal section disposed sequentially along a longitudinal axis. The distal section has feature(s) that allow the implant to be inserted laterally into the interspinous space, such as an approximately helical groove and/or a thread-like structure. The distal tip of the implant tapers inwardly, and may be rounded. The proximal section may include an outwardly extending wing or flange. The implant may include a main body that includes the wing or flange and a spacer slidably mated to the main body through the wing or flange.

  • Publication number: 20130253595
    Abstract: A procedure for implanting a bone anchor which has thread characteristics on the distal shaft adjacent the tip suitable for engaging bone cement and different thread characteristics on the proximal shaft adjacent the head suitable to engage and secure the anchor to natural cancellous and cortical bone. The thread on the distal shaft is designed to engage and secure the anchor to bone cement embedded within the bone without fracture of the bone cement. In particular embodiments, the distal shaft bears two threads which merge to form a single proximal thread on the proximal shaft, the distal threads having half the pitch of the proximal thread.

  • Patent number: 8430916
    Abstract: A spinal rod connector is adapted to connect two spinal rods. The spinal rod connector includes first and second channels which are defined in a housing. The first and second channels can be urged together in order to capture first and second spinal rods when a fastener is actuated. The spinal rod connector allows the first and second rods to be positioned relative to each other in one of a parallel and a non-parallel manner prior to the fastener locking the first and second spinal rods in position.

  • Patent number: 8394127
    Abstract: A bone anchor comprising a self-centering ball-joint suitable for use in a spine stabilization prosthesis which supports the spine while providing for the preservation of spinal motion. The bone anchor has a deflectable ball-rod partially received in a socket of a housing formed in the head of the bone anchor. A centering rod received partially in the ball-rod and partially within the housing operates to align the ball-rod with the longitudinal axis of the bone anchor. Deflection of the ball-rod bends the centering rod which in turn applies a restoring force upon the ball-rod.

  • Patent number: 8349013
    Abstract: A method for stabilizing at least one spinal motion segment includes an expandable spacer in a collapsed state into the interspinous space between superior and inferior vertebrae such that the spacer extends through the sagittal plane defined by the spinous processes of the superior and inferior vertebrae. The spacer has a flexible membrane defining an interior cavity. The method includes expanding the spacer to an expanded state by forcing a fill material in a fluid state into the cavity with the spacer disposed in the interspinous space, and thereafter solidifying the fill material to a solid state in the cavity. The method may be performed through a percutaneous penetration in the patient's skin and may cause the first and second vertebrae to be distracted.

  • Patent number: 8337536
    Abstract: A dynamic bone anchor for anchoring a spine stabilization assembly which supports the spine while providing for the preservation of spinal motion. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. Deflection of the deflectable post is controlled by a compliant ring. The force/deflection properties of the dynamic bone anchor may be adapted to the anatomy and functional requirements of the patient. The dynamic bone anchor may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion.
