Intracranial Pressure Monitoring Using a Newly Developed Transducer-tipped Ventricular Drainage Catheter

Intracranial Pressure Monitoring Using a Newly Developed Transducer-tipped Ventricular Drainage Catheter

A transducer-tipped ventricular drainage catheter (TVDC) was developed to allow continuous measure-ment of intracranial pressure (ICP) without interrupting cerebrospinal fluid (CSF) drainage. The 8.5 Fr catheter with a double lumen has 16 side holes for CSF drainage and a small silicone strain-gauge...

Zusammenfassung:A transducer-tipped ventricular drainage catheter (TVDC) was developed to allow continuous measure-ment of intracranial pressure (ICP) without interrupting cerebrospinal fluid (CSF) drainage. The 8.5 Fr catheter with a double lumen has 16 side holes for CSF drainage and a small silicone strain-gauge transeducer on the side of the catheter tip to measure the ICP directly. The transducer is composed of a 2×1 mm^2 silicone plate. Calibration must be performed before insertion.
