Codman Microsensor® ICP Transducer is MR Conditional at 1.5T and 3T Codman Microsensor ICP Transducer Direct Pressure Monitoring at the Source in Multiple Procedural Kit Configurations The Codman Microsensor® ICP Transducer consists of a miniature strain gauge pressure sensor mounted in a titanium case at the tip of a 100 cm 3F flexible nylon tube. The Codman Microsensor ICP Transducer monitors intracranial pressure directly at the source – parenchymal, subdural, or intraventricular. Small, Flexible and Low-Profile The small size and flexibility allows for low-profile tunneling under the scalp and kinking of the transducer without breakage or monitoring interruption. MR Conditional The Codman Microsensor ICP Transducer is MR conditional and may be imaged in the MR environment when used in accordance with the manufacturer’s instructions for use.1 Critically ill neurosurgical patients may benefit from the additional information gained through MR imaging for planning therapy and predicting outcomes.2 Elimination of Maintenance Requirements Associated with Fluid Coupled Systems The Codman Microsensor ICP Transducer eliminates the need for constant alignment of the transducer to the patient’s head and periodic re-zeroing. False readings associated with obstructions, air bubbles or movement of the patient fluid lines are no longer a concern.

Minimal Drift and Accuracy Figure 1: Comparison of Codman Microsensor ICP Transducer versus standard ventricular pressure as measured with an external fluid transducer (a) parenchymal, (b) subdural space and (c) ventricular fluid pressure. Studies performed on the Codman Microsensor ICP Transducer3,4,5 demonstrate a high degree of accuracy and stability in ICP monitoring. DRIFT (Mean) 0.9 + 0.2 mmHg - One study showed a mean drift of 0.9 mm Hg over an average 7.2 days of monitoring, with 25 percent of the sensors exhibiting no drift during the entire monitoring period3.
