摘要:
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 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.

摘要:
A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas.

摘要:
A system for minimally invasive medical procedures includes an elongate tubular access cannula comprising an elongate tubular member having a rigid proximal portion and an articulating portion. The tubular member has a first branch and a tubular bifurcation extending from the first branch, allowing simultaneous use of multiple instruments. A dissector suitable for use with the access cannula, or other access devices, for implantation of gastric bands or for other procedures includes a pre-curved distal portion having a dissection element such as a monopolar RF conductor and/or a dissection balloon, as well as a snare. In one method, the dissector is advanced around the posterior side of the stomach to form a tunnel in the connective tissue, and the snare is then extended from the dissector to engage a portion of the band and withdraw it through the tunnel.

An intestinal implant includes a proximal anchor self-expandable from a radially compressed position to a radially expandable position for engagement with a wall of the intestinal lumen and a flexible sleeve coupled to the anchor. The sleeve is implanted with the anchor downstream from the pylorus and the sleeve extending further downstream through the intestinal lumen.
