Patent ID: 8155757

Claim:
A cuff electrode comprising: a first elongate conductor; a second elongate conductor; a first pair of opposed curved electrically conductive plates electrically coupled to each other and to the first conductor; a second pair of opposed curved electrically conductive plates electrically coupled to each other and to the second conductor; a third pair of opposed curved electrically conductive plates electrically coupled to each other and to the first conductor, wherein the first, second, and third pairs of curved electrically conductive plates each have an electrically exposed interior surface; an elongate flexible shaft having a proximal region and a distal region and having the first and second conductors disposed along the shaft; a flexible curved cuff operably coupled to the shaft distal region, the cuff including a tubular body having an interior region and an exterior region, and having the first, second, and third curved electrically conductive plates operably coupled to the cuff tubular body interior region such that the electrically conductive plate interior conductive surface is electrically exposed within the cuff tubular body interior; the cuff tubular body includes a tubular body wall having a longitudinal slit therethrough allowing the cuff tubular body to open to expose the cuff tubular body interior, and in which the cuff tubular body is biased to urge the tubular body to close the slit; and the cuff further includes a generally triangular shaped flap with the base of the triangular shaped flap being the length of the tubular body and the base of the triangular shaped flap secured to the tubular body on a first side of the slit, in which the flap to extend around the tubular body and cover the slit.
