MULTI-INSTRUMENT ACCESS DEVICES AND SYSTEMS

摘要

A multi-instrument access device includes a base positionable within an opening (e.g. an incision or puncture) formed in a body wall and a dome-shaped seal on the base and positioned such that it is disposed outside the body wall during use. A plurality of instrument ports extend proximally from the seal for receiving instruments to be inserted into the body for use in a procedure. Tubular instrument tubes having pre-curved distal ends may be insertable through the ports for receiving the instruments and for orienting the operative ends of the instruments toward a target site.
