DUAL BALLOON CATHETER WITH SENSOR FOR CONTINUOSU TRANSVENOUS MEASURMENTOF INTRACRANIAL PRESSURE

摘要

An apparatus for the measurement of intracranial pressure in an area proximate to the jugular bulb from a minimally invasive insertion point exterior to the cranial cavity, comprising a narrow diameter intravascular catheter (20) and a conventional guidewire (32, not shown), a first proximal balloon (22) and a second distal balloon (24), an aperture (26) in the distal portion of the catheter (20) for accommodating a sensor (28) or emitter and an aperture (30) in the distal end (31) for accommodating the guidewire (32). An inflation/deflation mechanism (37) is connected to the catheter via an aperture (34) in the external wall of the catheter (20).
