Brain Surgery Made Safer With New Smart Needle
Researchers have developed a new high-tech medical device for safer brain surgery. The so-called "smart needle" is a tiny imaging device encased in a brain biopsy needle. It can help surgeons avoid damaging fatal blood vessels or those which can cause major or permanent damage to the brain.

Brain surgeries are among the riskiest types of medical procedures. Craniectomy specifically, a procedure in which the surgeon removes a portion of the skull, is among the most difficult type.
