The Problem
Brain Tumors: Out of the current 700,000 people with brain tumors, approximately 211,000 have malignant tumors that will likely require surgery [1].
Out of the 80,000 new brain tumor diagnoses per year, approximately 24,000 of them will require surgery [1].
Retractor Brain Damage: Between 10% - 36% of brain surgery patients may incur some type of tissue damage [2,3].
This brain tissue damage is caused by the pressure of a retractor, which can cause partial or total closure of blood vessels [2].
Retraction damage may result in bleeding within the brain tissue, aphasia, partial paralysis, numbness, and blindness depending on the region where damage takes place [4] .
There exists a need for a safe brain retraction device that is able to monitor and detect the state of the brain tissue and provide continuous feedback to the surgeon. Intraoperative monitoring of the electrical activity and pressure applied to the brain could significantly reduce the incidence of injury in deep brain surgeries.

The RetractiSens allows for real-time monitoring of brain tissue status during intracranial procedures involving brain retraction. Intra-operative monitoring of electrical activity and pressure is necessary while using a brain retractor to minimize retraction injury and clinically significant deficits. The RetractiSens gives surgeons vital information needed to make adjustments during surgery to reduce and prevent severe complications.
