Abstract:
A guide is disclosed for use in performing spinal surgery to prepare across a spinal disc and adjacent vertebrae an implantation space. The guide is associated with a computer controlled surgical navigation system employing an energy-detecting array to track positions of the guide in three dimensional space relative to a known reference point. The guide comprises a body for providing protected access to prepare across the spinal disc and into the adjacent vertebrae the implantation space. The body has a passage adapted to receive a bone removal device for forming the implantation space through the body. At least one electrically energizable energy emitter array is attached to the body for use in identifying the location of the guide relative to the adjacent vertebrae. A system and method for using the guide in spinal surgery are also disclosed.
Abstract:
Methods and instruments are provided for performing spinal disc space preparation and implant insertion in minimally invasive procedures. The instruments include cutting instruments and implant insertion instruments adapted for insertion through a minimally invasive access portal to a spinal disc space. The proximal portions of the instruments are adapted to facilitate viewing through a proximal end opening of the access portal with the instruments positioned through the access portal while also enhancing the surgeon's control of the distal working end of the instruments while in the disc space.
Abstract:
Laterally expanding vertebral spacer devices are provided for repairing damaged vertebral discs. The vertebral spacer devices maintain the height of a distracted vertebral disc space while providing stability to the spine. In one form of the invention, a vertebral spacer device is provided with a first arm movably coupled to a second arm. The first and second arms are laterally expandable from a first width for insertion into the disc space to a second width after insertion into the disc space. The first and second arms also define a cavity therebetween for placement of bone growth material.

Abstract:
The present invention relates to substituted triazole compounds and compositions comprising substituted triazole compounds. The invention further relates to methods of inhibiting the activity of Hsp90 in a subject in need thereof and methods for preventing or treating hyperproliferative disorders, such as cancer, in a subject in need thereof comprising administering to the subject a substituted triazole compound of the invention, or a composition comprising such a compound.
Abstract:
Systems and methods for administering trade orders are described. An embodiment comprises receiving, from a first server operated by a first trader, a communication including a first trade order and one or more selection criteria, the first trade order including at least one of a specified instrument, a specified quantity, and a specified price; determining that a database of trade orders does not contain a trade order matching the first trade order; identifying a plurality of traders satisfying the selection criteria; sending, to a plurality of second servers, a query including at least one of the specified instrument, the specified quantity, and the specified price; receiving, from a one of the plurality of second servers operated on behalf of a second trader, a positive response to the query; and facilitating execution of a trade between the first trader and the second trader for the specified instrument at the specified price.
Abstract:
An electronic trading marketplace (ETM) communicates with interfacing modules interfacing directly with order management systems (OMS's) at trading institutions. The interfacing modules automatically transmit orders from the OMS databases to the ETM and update the OMS databases in response to orders executed at the ETM. Traders can communicate with the ETM to anonymously negotiate trades of securities.
Abstract:
A trading platform and trading method that allows access to additional pools of liquidity is described. Other embodiments are also described.
