1. A device for measuring at least one physiological parameter in a body, said device comprising:
- a. an endoprosthesis located within said body, said endoprosthesis defining an inner surface and an outer surface, b. a first sensing means adapted for chronic implantation within said body, said first sensing means disposed closer to said outer surface of said endoprosthesis than to said inner surface of said endoprosthesis, c. a second sensing means adapted for chronic implantation within said body, said second sensing means disposed closer to said inner surface of said endoprosthesis than to said outer surface of said endoprosthesis, d. a means for wireless data transmission, e. a power source.

Abstract
A device for measuring physiological parameters within an aneurysm sac that has been excluded from blood flow by an endoprosthesis. The device is comprised of at least two sensors, one placed in the aneurysm sac and another in a systemic artery. A differential between the readings of the two sensors can then be calculated, making the device easily calibrated in vivo and insensitive to changes in atmospheric pressure.
