Tiny Cameras Implanted in Brain Biopsy Needles Could Help Surgeons Minimize Bleeding

A tool currently in development helps brain surgeons detect blood vessels and avoid bleeding. A fiber-optic camera housed within a biopsy needle alerts surgeons to the presence of blood vessels.

Rupturing even a small blood vessel in the brain can cause serious problems, and could potentially be fatal. Surgeons believe the tool could make procedures safer and more precise.
