Abstract:
1. A surgical access device for providing surgical access in a patient, comprising: an elongate member comprising an expansion lumen between a proximal end and a distal end; and a first expandable body operably attached to the distal end of the elongate member, percutaneously insertable through an incision to an internal location in a collapsed configuration, and the first expandable body expandable outward to an expanded configuration configured to exert pressure directly against anatomical structures thereby moving those structures out of an access path for surgical instruments to be inserted through an operating lumen of the first expandable body in the expanded configuration; a cannula for placement through the first expandable body when the first expandable body is in the expanded configuration; a second expandable body in axial alignment with the first expandable body operably attached to the distal end of the elongate member, percutaneously insertable through an incision to an internal location in a collapsed configuration; expandable inward to a constricting configuration to constrict about and anchor the cannula; and wherein the elongate member is configured to extend through the incision to a location external to the patient when the second expandable body is inserted to the internal location.
