    Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Electrodes may also be formed on flexible circuit assemblies integrated within or along the hood. The circuit assemblies may also provide structural support to the hood during delivery and/or deployment. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.

    Abstract: A medical manipulation assembly comprises an elongated distal steerable portion with a distal working channel extending through the elongated distal steerable portion. The assembly also comprises an elongated proximal steerable portion arranged proximally of the elongated distal assembly portion. A proximal working channel extends through the elongated proximal steerable portion. The assembly also comprises a distal steering mechanism to bend the distal steerable portion in response to movement of the distal steering mechanism. The assembly also comprises a proximal steering mechanism to bend the proximal steerable portion, independently of the distal steerable portion, in response to rotational movement of the proximal steering mechanism. The assembly also comprises distal pullwire(s) extending between the elongated distal steerable portion and the distal steering mechanism and proximal pullwire(s) extending between the elongated proximal steerable portion and the proximal steering mechanism. The distal and proximal portion working channels are configured to receive a visualization instrument.

    Abstract: A system for visualizing a tissue region of interest comprises a deployment catheter defining a lumen and a hood coupled to and extending distally from the deployment catheter. The hood has a low-profile configuration within a delivery sheath and a deployed configuration when extended distally of the delivery sheath. The hood in the deployed configuration defines an open area in fluid communication with the lumen. A distal portion of the deployment catheter extends into the open area. An imaging element is coupled to an imager support member. When in the deployed configuration, the imaging element is configured to extend distally of the distal portion while the imager support member extends within the deployment catheter. The imaging element comprises a tapered surface and the deployment catheter comprises a complementary tapered surface. Retraction of the imaging element causes the imaging element to shift radially outward from a longitudinal axis.
