Intravascular filter membrane with shape memory

摘要

An intravascular device can capture embolic debris. An intravascular filter can employ a shape memory filter membrane. In particular, an intravascular filter membrane can be designed for deployment in a vascular system. The filter membrane can be made of a shape memory polymer, and the membrane filter can be moveable between a collapsed insertion configuration and an expanded deployment configuration. The shape memory polymer remembers the expanded deployment configuration.
