Abstract:
A device for applying an axial force includes a longitudinal axis with a first compression surface located at a first end of the longitudinal axis and a second compression surface located at a second end of the longitudinal axis. A plurality of resilient members is positioned between the first compression surface and the second compression surface. A first resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. A second resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. The device has a compressed state and an expanded state where the first compression surface and second compression surface move in a direction of the longitudinal axis between the compressed state and the expanded state.
