Abstract
The present disclosure relates to systems and methods of detecting a tissue property during a laparoscopic surgical procedure with a tissue property sensing device. The method may include positioning a sensing assembly disposed along a distal portion of a tissue property sensing device about target tissue in a body cavity, inflating a bladder to compress and occlude blood flow of the target tissue, sensing a pressure measurement of pressure in the bladder and a light amplitude measurement of light projected through the target tissue, and determining a systolic blood pressure of the target tissue based on the pressure measurement and the light amplitude measurement.
