Abstract: A medical implant device has in one embodiment a receiver member for receiving an elongated member, a crown member, an anchor member and a retaining member. An embodiment of the receiver member has an axial opening, a transverse channel, a chamber including at least one substantially flat wall, and a groove. An embodiment of the crown member has at least one substantially flat side. An embodiment of the anchor member has a head with at least one substantially flat surface that may be parallel to the anchor member's longitudinal axis, and an anchoring portion. An embodiment of the retaining member is a substantially flat clip. The crown member and anchor member are inserted into the chamber, and the retaining member is inserted into the groove beneath them. The anchor member may be pivoted substantially in one plane with respect to the receiver member until locked.

Abstract: An apparatus for use in orthopedic distraction or compression is disclosed. In the illustrated embodiments, two arms are provided that are connected by a rod or bar with a mechanism that enables the arms to be brought toward or away from each other. At the end of each arm, a tip for connecting to a bone implant is provided. The tips are pivotable with respect to the arms, and have an opening with a tab that allows insertion of an implant head having branches defining a channel. Once the tips are appropriately positioned, connected and locked to the bone implants, the mechanism can be operated to move the arms together in compression or apart in distraction.

Abstract: Audible and signaling information sent through a multi-line hunt group may be transmitted over long distances using packet or IP-enabled communication networks. At least one remote site is connected to the communication network. The remote site includes a switch interconnecting a plurality of subscribers. At least one multi-line hunt group is connected to the switch. The communication system also includes at least one service site connected to the communication network. The service site includes a switch connected to a service platform. At least one multi-line hunt group is connected to the switch. A gateway interfaces each multi-line hunt group and the communication network. Each gateway converts audible information received over communication lines and signaling data received over each signaling line into a data format acceptable by the communication network.

Abstract: A multi-axial bone fixation implant includes an elongated member, one or more bone anchor assemblies, and stabilizer members fitted within the elongated member. A bolt having a bone-threaded end and a machine-threaded end and an enlarged medial portion is also provided. The bolt is anchored into a bone, and its machine-threaded end passes through the elongated member and the stabilizer, and is engaged by a coupled washer and nut. The washer includes an oblong aperture, and the nut includes a projecting sleeve. The sleeve is inserted into the washer and expanded, and the washer retains the sleeve without impairing relative rotatability or translatability of the nut and washer. When locked by the nut and washer, the enlarged portion of the bolt is forced against the stabilizer, which locks against the elongated member. The elongated member can be fixed with respect to the anchor at an infinite number of multi-axial angles.

Abstract: A spinal implant system is disclosed for the fixation of bone segments in the spine. The system includes an elongated member, one or more bone anchor assemblies, and stabilizer members which are fitted within the elongated member. A bone anchor is attached to a bone, and the elongated member and stabilizer are fitted over the bone anchor. A rounded washer and nut having a corresponding rounded underside surface are fitted on to the bone anchor over the elongated member, and tightened. The configuration of the bone anchor assembly, including an intermediate portion of the bone anchor, the arcuate washer, and the nut, along with the configuration of the sliding support, allows multi-axial positioning of the bone anchor with respect to the elongated member at a plurality of locations along a slotted member.

Abstract: A multi-axial bone fixation implant includes an elongated member, one or more bone anchor assemblies, and stabilizer members which are fitted within the elongated member. A bone bolt having cancellous threads on one end and machine threads at the opposing end and an enlarged portion between these sections is also provided. The bone bolt is anchored into a bone via the cancellous thread end. The machine threaded end passes through an opening of the elongated member and the stabilizer, and is engaged by a coupled washer and nut. The washer includes an undercut within its oblong aperture, and the nut includes a projecting sleeve. The sleeve is inserted into the washer aperture and expanded, so that the undercut retains the sleeve within the washer without impairing the rotatability or translatability of the nut and washer with respect to each other.
