Abstract: An anatomical probe system comprises an elongated flexible body and an elongated probe extending within the flexible body. The probe has a distal opening at a distal face of a distal end and includes an outer wall defining a channel, an access port in the outer wall in communication with the channel, a one-way flow controller, and an image capture instrument secured to the outer wall at a location proximal of the distal opening. The access port is spaced proximally of the distal face of the distal end. The one-way flow controller includes a cover configured to move between an open position where the access port is uncovered and the channel is in fluid communication with an area adjacent to the elongated probe via the access port, and a closed position where the access port is covered and a migration of fluids through the distal opening is permitted.

Abstract: An improved system for simplifying a complex waveguide network in a satellite system is described herein. A waveguide network device may be configured with at least two housing portions attached together. This enables the waveguide network device to receive an arbitrary number of waveguide routes and output the routes in any configuration, effectively simplifying the overall waveguide network architecture.

Abstract: A tissue shaping device adapted to be deployed in a lumen to modify the shape of target tissue adjacent to the lumen. In one embodiment the device includes first and second anchors; a connector disposed between the first and second anchors; and a focal deflector disposed between the first and second anchors and may be adapted to extend away from the lumen axis and toward the target tissue and/or away from the lumen axis and away from the target tissue when the device is deployed in the lumen. The invention is also a method of modifying target tissue shape. The method includes the steps of providing a tissue shaping device comprising proximal and distal anchors, a connector disposed between the proximal and distal anchors, and a focal deflector; placing the tissue shaping device in a lumen adjacent the target tissue; applying a shaping force from the focal deflector against a lumen wall to modify the shape of the target tissue; and expanding the proximal and distal anchors to anchor the device in the lumen.
