Abstract
A system for performing minimally invasive medical procedures includes an elongate support advanceable into a body cavity. The elongate support supports a 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 using pivotable frame members 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.
