摘要：
A method of providing access to tissue for a surgical instrument through a body wall is provided. The method includes providing an expandable retractor having a flexible sheath, the retractor being in a collapsed state; introducing the retractor into the body and placing the retractor adjacent the tissue; expanding the retractor; deploying the flexible sheath by engaging the flexible sheath with a tool and driving the flexible sheath through the body wall with the tool; and inserting the surgical instrument from outside the body through the flexible sheath to provide access to the tissue by the surgical instrument.
