Abstract
A spring assembly includes a resilient member having a first and second end shanks and a central helical portion. The first end shank extends in a first direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The second end shank extends in a second, opposite direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The central helical portion includes one or more coils disposed about a central longitudinal axis, and has a first end attached to the proximal end of the first end shank and a second end attached to the proximal end of the second end shank. The axes of the shank ends and the axis of the central helical portion are parallel or are collinear. The assembly also includes an attachment site at each of the end shanks.
