Claim Text:
1. An electrode array and delivery assembly, said assembly comprising: a core formed from flexible material, said core having a longitudinal axis that extends proximally to distally, and at least two opposed side surfaces that are laterally spaced apart from each other wherein, one of the side surfaces is a first side surface; an electrode array separate from said core, said electrode array including: first and second bridges that, longitudinally, extend proximally to distally and that are laterally spaced apart from each other; at least one first beam formed from elastic material that extends laterally between said first bridge and said second bridge so as to connect said bridges together; at least one first tab that extends laterally outwardly from said first bridge towards said second bridge and that is separate from both said second bridge and said at least one first beam; and an electrode mounted to said at least one first tab wherein, said electrode array is wrapped around said core so that: said first bridge and second bridge are at least partially located in separate spaces between the spaced apart side surfaces of said core so that said bridges at least partially overlap each other; said at least one first beam is wrapped around the first side surface of said core; and said at least one first tab projects away from the first side surface of said core and said at least one first beam; a sheath disposed over said core and said electrode array so as to prevent unwrapping of said electrode array from said core; and at least one steering cable disposed in said sheath and anchored to said sheath so as to selectively flex said sheath, and wherein said sheath is removably disposed over said core and said electrode array so that the extraction of said sheath away from said core and said electrode array allows the release of energy in said at least one first beam so that said at least one first beam unwraps said electrode array from said core so that said core can be withdrawn away from the unwrapped electrode array.
