1. A catheter, comprising:
- an inflation balloon inflatable within a vessel; and
at least one chain electrode extending around at least a portion of a periphery of the inflation balloon, the at least one chain electrode comprising a circumferential ring formed from a plurality of individual closed rings linked around the periphery of the inflation balloon, wherein each individual closed ring comprises no more than two linking points, the at least one chain electrode being expandable as the inflation balloon is inflated and contractible as the inflation balloon is deflated, the at least one chain electrode maintaining an axial position orthogonal to a length dimension of the inflation balloon, and the at least one chain electrode being configured to provide at least one of ablation, electrical stimulation, or electrical sensing.

Abstract
A catheter includes an inflation balloon and at least one electrode. The inflation balloon is inflatable within a vessel. The at least one electrode extends around at least a portion of a periphery of the inflation balloon. The at least one electrode is expandable as the inflation balloon is inflated, and contracts as the inflation balloon is deflated. The at least one electrode is held in place along a length of the inflation balloon with a tether member, which is secured at opposing distal and proximal ends of the inflation balloon.
