Nerve modulation system having helical guide
First Claim
Patent Images
1. A system for nerve modulation, comprising:
- a first elongate element having a distal end and a proximal end, a groove extending along the first elongate element forming a helical guide having a proximal end and a distal end, the helical guide extending around the first elongate element and along a length of the first elongate element;
a second elongate element having a distal end and a proximal end, the second elongate element including an atraumatic ablation element proximate the distal end of the second elongate element, the second elongate element movably disposed within and extending along the groove such that the second elongate element is wrapped around the first elongate element; and
a sheath disposed about both the first and second elongate elements,wherein pulling proximally on the proximal end of the second elongate element causes simultaneous radial and longitudinal displacement of the ablation element by causing the second elongate element to slide within the helical guide.

Abstract
Systems for nerve modulation and methods for making and using the same are disclosed. An example system for nerve modulation may include a first elongate element having a distal end and a proximal end and having a helical guide having a proximal end and a distal end. The system may also include a second elongate element having a distal end and a proximal end and having a nerve modulation element proximate the distal end. A sheath may be disposed about both the first and second elongate elements. Pulling proximally on the proximal end of the first elongate element may cause simultaneous radial and longitudinal displacement of the nerve modulation element.
