Neuropace/Visualase

NeuroPace RNS

Reactive neural stimulation (RNS®, NeuroPace, Inc.) is a treatment option that does not require surgical removal of brain tissue (resection). RNS is a new implantable device that delivers responsive neurostimulation by detecting abnormal electrical activity in the brain and delivering imperceptible levels of electrical stimulation to normalize brain activity before the patient begins to experience a seizure. The FDA approved NeuroPace RNS to treat medically refractory seizures in November 2014, and UCSF is one of the first centers on the west coast to provide this novel surgical therapy to patients.


Visualase

It is a minimally invasive procedure in which a thermal laser is used to destroy the epileptic tissue in the brain. This surgery can be used on patients who have afocal epilepsy and do not wish to pursue traditional surgery. Thermal energy is delivered to the target area (the lesion) using a laser probe. As light is deposited into the lesion the temperatures in the target area begins to rise, destroying the unwanted tissue in minutes. Because Visualase procedures are guided by MRI images, the procedure can provide precise targeting. The procedure is minimally invasive and has been reported in medical journals to be pain free and require a short recovery time. The technology is presently limited to only those patients with small well-defined epilepsy causing lesions, and deep brain lesions.

Advanatges of Visualase Laser Ablation Technology

· Requires no radiation

· Requires only a small 4mm incision, instead of the large skull opening in traditional craniotomies.

· May cause little or no pain during or after procedure

· Is minimally invasive, access smaller than typically created during a biopsy

· Usually requires only a one day hospital stay

· Does not limit use of additional or other treatment options

· Is often performed on otherwise inoperable tumors/lesions
