(57) ABSTRACT
A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes an expandable frame that carries a pair of tool cannulas, each of which has a lumen for receiving a tool useable to perform a procedure in the body cavity. The frame is expandable to orient the tool cannulas such that they allow the tools to be used in concert to carry out a procedure at a common location in the body cavity.
