Integral electrode placement and connection systems
First Claim
1. A tissue treatment assembly, comprising:
- an elongate catheter extending along a longitudinal axis and defining a fluid lumen therethrough, the elongate catheter terminating at a distal opening in communication with the fluid lumen;
a fluid barrier projecting distally of the distal opening of the catheter and configurable between a low profile and a deployed profile, wherein in the deployed profile, the fluid barrier defines an open area in fluid communication with the distal opening of the catheter and includes a distal membrane extending in a plane that intersects the longitudinal axis, the distal membrane defining at least one aperture such that the open area is in communication with an environment external to the fluid barrier; and
at least one arm member formed from a polymeric assembly extending distally along the fluid barrier and at least partially upon the distal membrane.

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.
