1. A sensing device comprising:

  • a sheath having a longitudinal axis, a proximal end, a distal end, and a wall having an outer surface and an inner surface and defining an inner lumen extending substantially in the direction of the longitudinal axis;

    an integration component attached to the sheath and having an inner space and an attachment portion configured to interface with the sheath to maintain fluid seal, the sheath having a space therein to allow a static column of liquid to reside adjacent the integration component;

    a thermal sensing device adjacent the inner surface of the wall of the sheath and terminating distally adjacent the distal end of the sheath, the thermal sensing device adapted to measure and relay the temperature of fluid in or adjacent a surgical site; and

    a pressure sensing device located adjacent the integration component and having a sensing portion adjacent or in the inner space of the integration component, the static column of liquid extending from the distal end of the sheath to the sensing portion of the pressure sensing device, the pressure sensing device configured to measure and relay information based on the pressure of the static column of liquid to be used to calculate the pressure at the surgical site.
