ABSTRACT:
An interstitial tissue pressure measuring device comprising a cannula and a catheter, the catheter being adapted to pass through the cannula and the distal end of the catheter being provided with a plurality of longitudinal slits defining a plurality of petals between them. When the cannula is emplaced in an interstitial tissue site and the catheter is passed through the emplaced cannula into the tissue, the petals facilitate measurement of pressure by a pressure-sensing device at the proximal end of the catheter.
