Abstract
The disclosure describes a method including manufacturing a shape memory polymer fabric with a collection of shape memory polymer fibers such that the resulting shape memory polymer fabric has a glass transition temperature of greater than 50 degrees centigrade. The method further includes training the shape memory polymer fabric with a pre-determined percentage of strain between an expanded shape and a contracted shape. The method further includes preparing a portion of the shape memory polymer fabric into a shape that is sized to cover two portions of a ruptured soft tissue of an animal with a mean body temperature below 40 degrees centigrade while the fabric has the predetermined percentage of strain stored in the expanded shape.
