A stent for treating a physical anomaly. The stent includes a skeletal support structure for expanding in the physical anomaly and a shape memory material coupled to the skeletal support structure.

Stent with expandable foam

A system comprising first, second, and third shape memory polymers (SMPs); wherein (a) the first SMP is a biodegradable open cell foam that includes a first channel; (b) the second SMP includes a second channel and is included in the first channel; (c) the foam is in a first state and is configured to expand to a second state, radially outward from the second foam, in response to thermal stimulus; (d) the third SMP is between the first and second SMPs and includes a stent having a first strut that includes the third SMP and a second strut that includes the third SMP; and (e) each of the first, second, and third SMPs is coupled to a wire.

The invention provides materials and methods for modeling human blood vessels. Including panels of anatomically accurate vascular phantoms, such as carotid artery phantoms, comprising a range of stenotic conditions and other geometric variations; methods of making anatomically accurate vascular phantoms using stereolithography with an input data set representation of a natural vascular lumenal surface to construct an anatomically accurate vascular phantom comprising a physical representation of the surface; and methods of using the subject phantoms and panels of phantoms, such as methods of measuring a parameter of fluid flow through a panel of anatomically accurate vascular phantoms comprising a range of stenotic conditions.
