Abstract

A vascular graft includes deformable sleeves that include an electrical component. The electrical component can be variable-resistance or piezoelectric, in embodiments, such that deformation of the sleeves due to pressure changes create or modify an electrical signal. A transponder can then transmit information relating to the pressure inside and outside of the vascular graft.
