摘要：
An apparatus includes a component having a shape memory material. The shape memory material has a first shape including a substantially elongate segment. The shape memory material has a second shape including a helix having a first ring and a second ring configured to exert a compressive force on a membrane interleaved between the first ring and the second ring and lying in a plane substantially perpendicular to an axis of the helix, the shape selectable based on an external stimulus.
