About 3 in every 1,000 U.S. newborns suffer from moderate to severe hypoxic-ischemic encephalopathy (HIE), which can cause severe neurological injury or death and which so far has been untreatable. The Cool-Cap Neonatal Head-Cooling System (Olympic Medical, a unit of Natus Medical) aims to correct that. It lowers brain (but not body) temperature to reduce neurological injury. A quick response is vital, and this device is ready within 15 minutes, combining diagnosis and therapy. Just as important, it's very easy to set up and use. Doesn't seem like rocket science, but its sound engineering and extreme ease of use are compelling.
A Truly Noninvasive Thermometer
Perhaps an "obvious" idea. But the developer (Kaz, Inc.) made this Vicks Forehead Thermometer work. Based upon infrared illumination, it monitors the subcutaneous temperature of the temporal artery. It's reportedly very comfortable for use in children, and its LCD display is color-coded for normal/abnormal readings. And, it's intuitive; a child's forehead is the obvious first choice for fever assessment.
Hematocrit by Ultrasound
Determining blood hematocrit (percent red-cell volume) is pretty standard stuff, so why do we need another method? Well, the UltraCrit Hematocrit Measurement Device is quick (30 seconds), miniaturized, accurate, and uses little blood (1 drop). Its developer (Separation Technology) took several years to perfect its low-energy ultrasound method. It is too soon to know where it will find greatest use, but the successful development of this clever, new approach to a well-established medical need makes it for me.
Patient-Specific Tissue Ablation
There has not been a reliable way to remove tissue characterized as Barrett's esophagus, a precancerous state of esophageal tissue, until now. The Halo360 Esophageal Tissue Ablation System (Barrx Medical, a unit of Stellartech Research) apparently does the job by ablating offending tissue to just the right depth. This is achieved by first deploying a sizing balloon to measure the patient's anatomy, then deploying the appropriately sized ablation catheter and its bipolar radiofrequency electrode array. The system thereby achieves a uniform circumferential ablation depth less than 1 millimeter. Very neat!
