Unmet Need
Single-use, disposable intracranial pressure sensing catheter that can be passed under the scalp for improved hygiene
Approach
Develop a low-profile catheter with connector that can be passed under the scalp with minimal dilation.
Product Features
Sensing based on use of a single optical fiber with Fabry-Perot interferometric cavity fabricated on distal tip. Deflection of 3-micron thin silicon diaphragm measured with a laser and interferometer inside the box. Novel, locking, quick-release fiberoptic connector has the world’s smallest cross-section; achieves extremely low losses, low cost, and ease-of-use. System measures pressure to within 0.05 psi (1mm Hg).
