  • a shaft including a distal end and a proximal end; and

    a helical coil including a proximal end attached to the distal end of the shaft, a plurality of spaced apart body portions each having bends forming a helix, and a distal tip shaped as a loop, wherein first and second bends formed adjacent the loop orient the loop at an angle relative to a longitudinal axis extending through the helical coil, at least one body portion having an angle relative to the longitudinal axis that is substantially the same as the angle at which the loop is oriented, wherein the loop is oriented at an angle relative to the longitudinal axis such that the distal tip is spaced a distance from the longitudinal axis, the body portions having a substantially same diameter along an entire length of the helical coil.
