Off-wall electrode device and methods for nerve modulation
First Claim
1. A system for nerve modulation through a wall of a blood vessel, comprising:
- an elongate member extending along a central elongate axis and having a proximal end and a distal end, the elongate member having a radially expandable member disposed proximate the distal end; and
a tubular sheath cooperatively engaged with the expandable member such that the expandable member is not expanded when in the tubular sheath and can expand when moved out of the tubular sheath,the expandable member comprising a plurality of electrodes on an expandable frame wherein each of the plurality of electrodes has a first surface that is entirely electrically insulated and faces radially outwards relative to the expandable member and a second surface that is electrically conductive surface that and faces radially inwards towards a central longitudinal axis of the expandable member.

Abstract
Systems for nerve modulation through the wall of a blood vessel are disclosed. An example system for nerve modulation may include an elongate member extending along a central elongate axis and having a proximal end and a distal end. The elongate member may have a radially expandable member disposed proximate the distal end. A tubular sheath may be cooperatively engaged with the expandable member such that the expandable member is collapsed when in the sheath and can expand when moved distally relative to and past a distal end of the sheath. The expandable member may include a plurality of electrodes and a plurality of spacer struts. Each spacer strut may be configured such that when the self-expanding member is in an expanded state the spacer strut extends out radially further than the electrodes from the central elongate axis.

9. A system for nerve modulation through a wall of a blood vessel, comprising:
-
an elongate member extending along a central elongate axis and having a proximal end and a distal end, the elongate member having a radially expandable member disposed proximate the distal end; and a tubular sheath cooperatively engaged with the expandable member such that the expandable member is not expanded when in the tubular sheath and can expand when moved out of the tubular sheath, the expandable member comprising a plurality of non-contact electrodes on an expandable frame, wherein each of the plurality of non-contact electrodes has a single electrically conductive surface, wherein the expandable member is configured such that when the expandable frame is expanded and in contact with a blood vessel wall, the electrically conductive surface of each of the plurality of non-contact electrodes does not contact the blood vessel wall and faces radially inward towards a central longitudinal axis of the expandable member. - View Dependent Claims (10, 11, 12, 13, 14)
