    Abstract: An apparatus for performing surgical procedures is disclosed including a flexible entry guide tube and a first steering device. The guide tube has one or more lumens extending along its length from a proximal end to substantially at or near a distal end. At least one of the one or more lumens is an instrument lumen with open ends to receive a flexible shaft of a surgical tool. The first steering device is insertable into the instrument lumen to shape the guide tube as it is inserted through an opening in a body and along a path towards a surgical site. The apparatus may further include a flexible locking device to couple to the flexible entry guide tube and selectively rigidize the guide tube to hold its shape. The guide tube may be steered by remote control with one or more actuators.

    Abstract: A stiffening assembly comprises an outer tube including a longitudinal axis, an inner tube extending along the longitudinal axis, and a plurality of laminar elements between the outer tube and the inner tube and separate from the outer tube and the inner tube. The stiffening assembly is adjustable between a flexible state in which each laminar element of the plurality of laminar elements is movable and a stiffened state in which an applied vacuum clamps the plurality of laminar elements between the outer and inner tubes such that a transfer of forces between the plurality of laminar elements stiffens the stiffening assembly. At least one laminar element of the plurality of laminar elements has a different thickness than at least another laminar element of the plurality of laminar elements.

    Abstract: A cannula can include a body with proximal and distal portions and a lumen extending through the body, the distal portion configured for insertion into a patient anatomy. An energy interface can be positioned in the proximal portion, and a light emitting device can be coupled to the energy interface and configured to emit light from the body. A system can include the cannula, a support structure, and an energy source. The support structure can include another energy interface that transfers energy to/from the energy interface. The energy source can be coupled to the cannula via the energy interfaces, where the light emitting device emits light from the body in response to energy received from the energy source via the energy interfaces. One or more cannulae can be used to illuminate the patient anatomy.
