• Blackrock Microsystems (Salt Lake City) reported the launch of two new products designed to improve the monitoring and assessment of neural signals associated with brain electrical stimulation and behavior. The new products, Cerebus Stim Switch and NeuroMotive, are designed to assist researchers searching for new insights into brain communication that could have important applications in developing treatments for Parkinson's disease, epilepsy, addiction, sleep disorders and other neurological conditions. The Cerebus Stim Switch improves switching control for neural stimulation applications, an important capability in brain research. A single module enables programmatic switching among a maximum of 32 individual electrodes, while multiple modules can be combined to switch among a maximum of 256 electrodes. NeuroMotive provides real-time video recording, tracking and analysis of synchronized behavior and neurophysiology, allowing researchers to directly attribute subject behavior to specific brain activity.

• Covidien (Boulder, Colorado) reported the launch of Mallinckrodt TaperGuard and TaperGuard Evac endotracheal tubes. The TaperGuard line of endotracheal tubes uses a taper-shaped cuff made from polyvinylchloride (PVC) that is designed to substantially reduce the risk of microaspiration. The TaperGuard Evac endotracheal tube additionally provides for secretion drainage through an integrated suction lumen. Microaspiration refers to the entry of foreign material into the respiratory tract. Covidien says TaperGuard's cuff design substantially reduces microaspiration by an average of 90%, versus the conventional barrel-shaped PVC cuff, found on the most widely used endotracheal tube – the Mallinckrodt Hi-Lo endotracheal tube.

• OrSense (Nes Ziona, Israel) said that results from a multi-center study indicate that NBM-200MP, a continuous, non-invasive monitoring system, measures levels of oxygen saturation and hemoglobin accurately and reliably in comparison to accepted methods. OrSense says the NBM-200MP system offers accurate non-invasive, continuous measurements of both Hb and oxygen saturation in states of hypovolemia, hypothermia and vasoconstriction or during open heart surgery, as well as during regular perfusion. The NBM-200MP operates via a ring-shaped sensor that is fitted on the patient's finger and applies a pressure, temporarily occluding the blood flow. During the occlusion optical elements in the sensor perform a sensitive measurement of the light transmitted through the finger. This method, called Occlusion Spectroscopy, provides a quick, accurate and painless measurement of the patient's blood constituents, while greatly improving patient comfort, eliminating infection risk, and providing the caregiver with superior accuracy and immediate results.
