Abstract
A catheter with a variable circular loop is responsive to a contraction wire for increasing the coiling of the circular loop. The shape of the loop is supported by an elongated member, wherein a radially constrictive sleeve confines the contraction wire to extends immediately alongside the length of elongated member so as to improve uniformity and minimize misshaping of the loop during contraction.
