Abstract
A shape-memory device manufactured from shape memory material includes multiple activation temperatures. The multiple activation temperatures arise from either the heat treatment of the device during manufacturing, or by combining different elements with different activation temperatures. To manufacture a shape-memory device with multiple activation temperatures, it is formed into a first shape. A first portion of the shape-memory device is heated to a first temperature, and a second portion of the shape-memory device is heated to a second temperature. The shape-memory device is then worked into a second shape. Accordingly, the first portion has a first transition temperature, and the second portion has a second transition temperature. In use, the shape-memory device is placed into a desired position. Energy is applied such that the first portion, second portion, or both portions are transformed.
