• Gambro (Lakewood, Colorado) said it is introducing what it calls "the latest innovation in dialyzer technology" — Polyflux Revaclear and Polyflux Revaclear MAX. The Polyflux Revaclear dialyzers feature a membrane technology and an advanced design, which combine to deliver outstanding clinical performance for treatment of dialysis patients. The high-flux dialyzers feature a new membrane that Gambro said is more efficient and more selective while retaining the same proven 3-layer membrane structure as the existing Polyflux dialyzer. The membrane is composed of a unique blend of the polymers PAES (Polyarylethersulfone) and PVP (Polyvinylpyrrolidone).

• Hemametrics (Kaysville, Utah) said that two presentations during the American Society of Nephrology's Renal Week demonstrated that frequently monitoring hemoglobin during hemodialysis will provide physicians with trending information that may reduce hemoglobin variability. The study demonstrated increased time-in-target range for hemoglobin in end-stage renal disease patients. The study suggests that increased frequency of hemoglobin monitoring may contribute to more accurate dosing for anti-anemia medication (e.g., erythropoietin stimulating agents, or ESAs) and lead to improved outcomes. The study used Hemametrics' Crit-Line III TQA hematocrit monitor. Crit-Line III-TQA is a fluid management and access monitoring tool used during hemodialysis that incorporates photo-optical technology to non-invasively measure absolute hematocrit, percent blood volume change, continuous oxygen saturation and access recirculation. Using red blood cells as the marker, Crit-Line determines the fluid volume change in the bloodstream during a dialysis treatment.

• Honda Motor Co. (Tokyo) has unveiled its second experimental walking assist device that helps support body weight to reduce the load on an individual's legs while walking, going up and down stairs, and in a semi-crouching position. The device is designed for people who are capable of walking and maneuvering on their own, but who can benefit from additional leg and body support while performing tasks. The new walking assist device with the body weight support system reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person's bodyweight. The device has a structure consisting of seat, frame and shoes, and the individual can put it on by simply wearing shoes and lifting the seat into position.
