An expandable interbody fusion device for implantation into the intradiscal space between two opposing vertebral bodies of a spine comprises a superior endplate member having an upper surface for engaging a superior vertebral body in a spine, and an inferior endplate member having a lower surface for engaging an inferior vertebral body in the spine. The superior endplate member and the inferior endplate member are releasably coupled and define a cavity therebetween. At least one expansion member is configured to be introduced into the cavity to move the superior endplate and the inferior endplate members relatively apart upon introduction and to thereby decouple the superior endplate member and the inferior endplate member. An inserter may be releasably coupled to the device to facilitate insertion of the device as well as to provide a track for insertion of the expansion members.

A tissue ablation probe, system, and method are provided. The ablation probe comprises an elongated member, an ablative element mounted on the distal end of the elongated member, and at least one thermoelectric device mounted to the member in thermal communication with the ablative element. The system may include the ablation probe, thermal control circuitry for controlling the thermal effect of the thermoelectric device, and an ablation source for suppying ablation energy to the ablative element. A plurality of circumferentially distributed thermoelectric devices can be provided, so that radial tissue sectors can be selectively affected by independently controlling the thermal effect of the thermoelectric devices. In one embodiment, the thermoelectric device(s) can be used to cool a heat ablative element. In another embodiment, the thermoelectric device(s) can be used to heat an ablative element, thereby forming a heat ablative element. In still another embodiment, the thermoelectric device(s) can be used to cryogenically cool an ablative element, thereby forming a cryogenic ablative element.

A frequency and protocol agile wireless communication product, and chipset for forming the same, including a frequency agile transceiver, a digital interface circuit for interconnecting the radio transceiver with external devices, protocol agile operating circuit for operating the radio transceiver in accordance with one of the transmission protocols as determined by a protocol signal and an adaptive control circuit for accessing a selected wireless communication network and for generating the frequency control signal and the protocol control signal in response to a user defined criteria Among the possible user defined criteria would be (1) the cost of sending a data message, (2) the quality of transmission link (signal strength, interference actual or potential), (3) the potential for being bumped off of the system (is service provider at near full capacity), (4) the security of transmnission, (5) any special criteria which the user could variably program into his omni-modal wireless product based on the user's desires or (6) any one or more combinations of the above features that are preprogrammed, changed or overridden by the user. The disclosed invention allows wireless service providers to broadcast electronically as part of any “handshaking” procedure with a omni-modal wireless product information such as (1) rate information and (2) information regarding system operating characteristics such as percent of system capacity in use and / or likelihood of being dropped. The disclosed invention creates a user oriented source enrollment and billing service in the wireless data market by establishing uniform standard for “handshakes” to occur between cell service providers and omni-modal wireless products. In addition, the disclosed invention can be implemented on a standard chip or chipset including a radio transceiver specifically designed to be used in all types of omni-modal wireless products.
