TNS.jpgTrigeminal Nerve Stimulation for Epilepsy Management

News Release from UCLA reports about promising results of a phase 2 clinical trial of trigeminal nerve stimulation (TNS) for controlling drug resistant epilepsy. Professor DeGiorgio, a lead inventor of the technology, reports that the latest trial has shown that 40% of patients treated with the system had a significant reduction in seizure frequency.

The external stimulator attaches to a belt or can slip into a pocket. Wires from the stimulator are connected to conductive pads attached to the forehead. The electrodes transmit a signal to the trigeminal nerve, which extends into the brain from the face and forehead and is known to play a role in seizure inhibition.

NovoTTF.jpgNovoTTF-100A for Treatment of Brain Tumors Wins FDA Clearance

NovoTTF-100A, a device for treatment of glioblastoma multiforme from Novocure, received FDA approval following a clinical trial and an agency panel recommendation. The device creates an electric field at the tumor site, preventing cancer cells from dividing and the tumor from growing. The system is indicated for patients following tumor recurrence after receiving chemotherapy.

According to a study of 237 subjects patients treated with the NovoTTF alone achieved a comparable overall survival time to patients treated with the physician's choice of the best chemotherapy. The rate of progression free survival at six months (PFS6) was 21 percent in the NovoTTF group compared to 15 percent in chemotherapy patients.

DuraSealExact.jpgCovidien DuraSeal Exact Gets FDA Approval

In a Press Release Covidien announces that FDA gave its approval for the company's DuraSeal Exact spine sealant, a device designed to help to fix teared dura during spinal surgeries. The material was developed for quick setting so as to prevent unnecessary leaking of spinal fluid, and comes in attractive blue so as to be easily seen when applying.

DuraSeal Exact spine sealant is formulated with a lower molecular weight than its predecessor, resulting in decreased post-application swelling and allowing surgeons to confidently use the product in spinal surgery. The product is absorbed over a 9-12 week time period, demonstrating a much longer persistence than fibrin glues.

Elana.jpgElana Device for Intracranial Artery Bypass Gets FDA approval

Standard bypass surgery in the brain requires clipping the artery to halt blood flow during the procedure. The ELANA (Excimer Laser Assisted Non-Occlusive Anastamosis) Surgical Kit allows neurosurgeons to create a bypass without shutting off the blood flow. It consists of a small platinum ring and a hand piece connected to a surgical laser and suction tubing.

Possible indications for the ELANA procedure includes cerebral aneurysm, tumors at the base of the skull that could impact blood flow in brain arteries, or other issues that could complicate conventional surgery.

Rehman2.jpgA substantial contribution to international neurosurgery

Dr. Safi Ur Rehman retired from his position as a neurosurgeon in Hong Kong more than 2 years ago. He read about the Ethiopian training program at NEUROSURGIC.com (read more here) and joined the programme as a teacher in late July 2010. He then served as a volunteer for 7 consecutive months, leaving late February 2011. During this period, he was joined by 8 other international colleagues serving for shorter periods. His presence thus gave teacher continuity to the programme; during the entire period he worked indefatigably, always with the patients’ best in mind.

RhinoChill.jpgRhinoChill Non-Invasive Head Cooling System

BeneChill (San Diego, CA) has partnered with Medtronic's Physio-Control division to release the RhinoChill IntraNasal Cooling System in Europe.  RhinoChill cools the head and body and is designed for fast application on patients status post cardiac arrest, stroke or traumatic brain injury.

The RhinoChill System uses a non-invasive nasal catheter that sprays a rapidly evaporating, inert coolant liquid into the nasal cavity, a large area situated beneath the brain that acts as a heat exchanger. As the liquid evaporates, heat is directly removed from the base of the skull and surrounding tissues via conduction and indirectly through the blood via convection.
