The shape-memory effect, as exhibited by metal alloys such as nitinol as well as many polymers, is the ability of a material to change its dimension in a predefined way in response to an external ...

MedShape (Atlanta, GA) has been granted a U.S. patent for a shape memory polymer-based technology used in orthopedic applications. Shape memory polymers can "remember" more than one shape and ...

Researchers at the Georgia Institute of Technology are developing unique polymers, which change shape upon heating, to open blocked arteries, probe neurons in the brain and engineer a tougher spine.

Imagine a world of shape-shifters. A surgeon inserts a small lump of plastic into an anesthetized patient and, like magic, it expands into a life-saving mesh tube that keeps a formerly clogged artery ...

Polymers that exhibit shape-memory effect (SME) are an important class of materials in medicine, especially for minimally invasive deployment of devices. Professor Subbu Venkatraman and his group from ...
