Abstract
An occlusive implant may include a framework configured to shift between collapsed and expanded configurations, and an occlusive fabric secured to the framework. The fabric includes shape memory characteristics such that the fabric is configured to shift from a first to a second configuration when exposed to a stimulus. A method of making the fabric includes intertwining a plurality of filaments into the fabric, defining a permanent shape of the fabric in the second configuration, and heat setting the fabric in the first configuration. A method of making a shape memory yarn includes forming a core filament, and wrapping at least one shape memory filament helically around the core filament. The at least one shape memory filament is formed from a shape memory polymer and is configured to shift from a first to a second configuration when exposed to a stimulus.
