Expandable electrode assemblies for forming lesions to treat dysfunction in sphincters and adjoining tissue regions
First Claim
1. An assembly for treating a tissue region at or near a sphincter comprisinga support structure comprising an array of jointed spines having proximal and distal ends joined to form a basket, at least one of the jointed spines including a molded hinge about which flexure occurs, a mechanism to flex the jointed spines to expand and collapse the basket, and electrodes carried by the jointed spines for advancement in a path to penetrate the tissue region upon expansion of the basket.

Abstract
Expandable assemblies for treating a tissue region at or near a sphincter comprises a support basket formed from an array of spines. A mechanism flexes the spines to expand and collapse the basket. Electrodes carried by the spines for advancement in a path to penetrate the tissue region upon expansion of the basket. The basket can be formed from a mechanical array of molded, jointed spines, or from an extruded tube having axial slits forming the spines.
