Abstract
Official abstract text for this publication.
A resistively heated shape memory polymer device is operated using resistive heating to heat the shape memory polymer device. The resistively heated shape memory polymer device is made by providing a wire that includes a resistive medium. The wire is coated with a first shape memory polymer. The wire is exposed and electrical leads are attached to the wire. In one embodiment the shape memory polymer device is in the form of a clot destruction device. In another embodiment the shape memory polymer device is in the form of a microvalve. In another embodiment the shape memory polymer device is in the form of a micropump. In yet another embodiment the shape memory polymer device is in the form of a thermostat or relay switch.
First claim
Opening claim text (preview).
The invention claimed is: 1. A micropump device, comprising: a micropump body, a moveable cylinder in said micropump body, a coil made from a wire embedded in shape memory polymer to provide said coil, wherein said coil includes a first loop of said wire embedded in shape memory polymer wherein said first loop is in a first loop shape, a second loop of said wire embedded in shape memory polymer wherein said second loop is in a second loop shape, wherein said second loop is adjacent said first loop, and a power source that provides a current to said coil and said current causes contracting of said coil, wherein said power source is turned on and off causing said current to said coil to be turned on and off resulting in said current alternatingly causing contracting of said coil moving said moveable cylinder in said micropump body for operating the micropump device.
