Devices and methods for tissue modulation and monitoring
First Claim
1. A device for stimulating or modulating tissue, said device comprising:
- an elongate member having a longitudinal axis, a proximal end, and a distal end;
a first pair of adjacent annular stimulating regions, the first pair of annular stimulating regions comprising a proximal annular stimulating region disposed near the distal end of the elongate member, and a distal annular stimulating region disposed near the distal end of the elongate member, the distal annular stimulating region closer to the distal end of the elongate member than the proximal annular stimulating region,wherein the proximal annular stimulating region comprises a plurality of independently energizable electrodes adapted to deliver current into the tissue, with adjacent electrodes in the proximal annular stimulating region separated from one another by an insulating member disposed on the elongate member, the proximal annular stimulating region circumscribing the elongate member, andwherein the distal annular stimulating region comprises a plurality of independently energizable electrodes adapted to deliver current into the tissue, with adjacent electrodes in the distal annular stimulating region separated from one another by an insulating member disposed on the elongate member, the distal annular stimulating region circumscribing the elongate member, andwherein the distal annular stimulating region is axially separated along the longitudinal axis from the proximal annular stimulating member by a gap; and
a first internal electrical connector entirely disposed near the distal end of the elongate member and electrically coupling a first electrode in the proximal annular stimulating region with a first electrode in the distal annular stimulating region, wherein the first internal electrical connector extends across the gap between the proximal and distal annular stimulating regions.

Abstract
A tissue stimulating device has an elongate member, a proximal annular stimulating region and a distal annular stimulating region. Each of the annular stimulating regions circumscribe the elongate member, and each has a plurality of independently energizable electrodes that deliver current into tissue. Adjacent electrodes in the annular stimulating regions are separated from one another by an insulating member. The annular stimulating regions are axially separated from one another by a gap. An internal electrical connector electrically couples a first electrode in the proximal annular stimulating region with a first electrode in the distal annular stimulating region. The first internal electrical connector is disposed within the elongate member, and extends across the gap between annular stimulating regions. A recording electrode is disposed in the gap and is adapted to record local tissue potentials from the tissue.
