Abstract: This invention relates to a orthopedic implant that comprises a shape memory polymeric material. The orthopedic implant can be fabricated or molded in a desired configuration selected to provide support or tension to bony structures. Examples of implantable devices include spinal rods, bone plates, and bone fixation cords. The orthopedic implant can be deformed to a second configuration different from the first configuration either prior to implantation or after implantation. When desired, the shape memory polymeric material can be induced to revert to it original molded configuration. This can compress the attached bony structure and/or promote arthrodesis.
Abstract: Instrumentation is disclosed for inserting an interbody spinal fusion implant for implantation at least in part within and across the generally restored height of a disc space between two adjacent vertebral bodies of a human spine. The implant has an external housing and a substantially hollow internal rotatable member having bone engaging projections that are deployable through the housing to penetrably engage the adjacent vertebral bodies.
Abstract: A system for illuminating a body orifice includes: a frustoconical optical waveguide speculum includes a distal end, a proximal end wider than the distal end, an at least partially circumferential body wall having a bore passing between the proximal and distal ends of the speculum; and a base that couples to the speculum and receives a light source such that the speculum is configured to propagate light from the light source along the body wall. In a preferred embodiment, the body wall defines between an inner and outer surface of the body wall a fluidic channel configured to delivery fluid to the distal end of the speculum and a suction channel configured to drain fluid from distal end of the speculum.

Abstract: A fixation device expands the spinal canal through osteotomies of the dorsal spinal elements (e.g lamina). Fixation is established to the dorsal vertebral elements (e.g. spinous process or lamina), with connection to a fixation device on each side of respective osteotomies. A distracting mechanism dorsally translates the fixated dorsal vertebral elements to expand the spinal canal. The fixation device allows secure fixation of the vertebra in the expanded state to promote bony healing across the osteotomy site. The fixation device can include a dorsal vertebral device (e.g., a transosseous fixation member placed through the spinous process) connected to a vertebral fixation device (e.g., bone screw or rod) by a connecting device with distracting mechanism. The connecting device spans the respective osteotomy, includes the distracting mechanism, and translates (lifts) the dorsal vertebral device from the vertebral fixation device in a dorsal direction to promote spinal canal expansion.
Abstract: A guiding device for use with a laryngoscope for assisting in the insertion of an endotracheal tube into a patient, the device comprising a guiding means for guiding an endotracheal tube through the patient's upper airways, and an attachment means to attach the guiding means to the blade of the laryngoscope. A laryngoscope comprising the guiding device is also disclosed.
Abstract: Expanding a spinal canal by drilling a cylindrical passage in each pedicle of a vertebra, making a circumferential pedicle cut (osteotomy) through each pedicle from within the passage, separating each pedicle cut by inserting an implant into the passage to distract the pedicle cut (i.e., lengthen the pedicle) to expand the spinal canal, and securing each pedicle cut, allowing the vertebra to heal with the spinal canal expanded. The implant can include an outer sleeve, an inner bolt, and expandable flanges. The outer sleeve includes an upper and a lower portion, with the expandable flanges therein. Rotation of the inner bolt causes the upper and lower portions of the outer sleeve to separate, causing the pedicle cut to widen and the expandable flanges to radially extend into and stabilize the widened pedicle cut for expansion of the spinal canal.
Abstract: A system for assisting in a surgical process, comprising: (a) a surgical device taken from a group consisting of a surgical tool and a surgical implant; (b) a positional sensor carried by the surgical device, the positional sensor including a wireless transmitter and associated circuitry for transmitting sensor data from the transmitter; and (c) a computer system including a wireless receiver and signal conditioning circuitry and hardware for converting sensor data received by the wireless receiver into at least one of (i) audio feedback of positional information for the surgical device and (ii) visual feedback of positional information for the surgical device.
Abstract: A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in a receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. A retaining member for capturing the shank in the receiver includes a sloping surface for a frictional, press fit, cammed engagement with the shank. A compression insert having a resilient structure provides non-floppy positioning of the shank with respect to the receiver and also independent locking of the shank with respect to the receiver.
Abstract: A spinal fixation device combines an open-headed anchor member, such as a bone screw or a hook with spaced apart arms forming a rod receiving channel. The arms have break-off arm extensions that are broken-off or separated after the rod is clamped. The closure and inner surfaces of the arms and tabs have mating helical anti-splay guide and advancement flanges formed thereon which radially interlock and mechanically cooperate to prevent splaying the arms and extensions as the closure is advanced into the rod receiving channel.
Abstract: Spine stabilization systems and integrated rods are disclosed. One spine stabilization system disclosed has at least four bone anchors and a stabilization member attached to the bone anchors. The stabilization member has first and second elongate portions interconnected by a connector portion. The first and second elongate members extend longitudinally and generally parallel to a central longitudinal axis and connector portion extends transverse to the central longitudinal axis from a first lateral end to a second lateral end. The connector portion is integrally connected to the first and second elongate portions such that there is no relative movement between the lateral ends and the respective elongate portion to which each end is attached.
Abstract: A device is disclosed for securing a spinal rod to the spine which includes a head portion configured to receive a spinal rod, a locking cap configured to engage the head portion and the spinal rod upon rotation of the locking cap relative to the head portion to secure the position of the head portion relative to the spinal rod, and a fastener portion depending from the head portion and configured to engage the spine. The locking cap has discontinuous opposed engagement flanges that are received within opposed engagement slots of the head portion when the locking cap is rotated into a locked position.

Abstract: Artificial disc replacements (ADRs) and total disc replacements (TDRs) are based upon two, directly articulating components, resulting in a restricted-motion system that better approximates more normal spinal flexion, extension, and lateral bending. Both components are preferably made of a hard material and are highly polished to reduce friction.
Abstract: An apparatus for implementing a spinal fixation system with supplemental fixation includes a spinal fixation rod assembly and at least one supplemental fixation device. The spinal fixation rod assembly is adapted to provide primary fixation at a plurality of first fixation points by being secured to a plurality of first vertebral components except not into one of the first vertebral components of the plurality that is in a weakened structural condition and located between other of the first vertebral components of the plurality. The supplemental fixation device is adapted to provide supplemental fixation for the assembly at a second fixation point by being secured to a second vertebral component located adjacent to and offset from the one first vertebral component in the weakened structural condition and also to interconnect with the assembly to provide anchorage and thus additional fixation supplemental to the primary fixation.
