Abstract

An in-vivo sensing device typically associated with an in-vivo imaging device may be adapted to measure endoluminal pressure or stress. The sensing device may include a substantially transparent base, a pressure-sensitive membrane, and fluid between the transparent base and the membrane. Incident light may be radiated through the substantially transparent base and the fluid of the in-vivo pressure-sensing device. This light may be reflected to a light detector, enabling measurement of in-vivo pressure on the membrane.
