Nipro Medical Corporation has launched a new version of its Elisio Polynephron Single Use, High-Flux, Hollow-Fiber Dialyzer. Both the housing and the membrane in the new version are made with material not containing BPA or DEHP. Elisio features a Polynephron membrane similar in function to that of a human kidney, the company said in a release.
“We have taken a dialyzer that delivers excellent clearance and reduced thrombogenicity, and improved it by eliminating any BPA or DEHP,” said Joe Dawson, senior vice president of Nipro North America. “Both chemicals are known endocrine disruptors. There are many published studies showing that endocrine disruptors cause adverse effects in animals. As a company that is focused on making products that improve the lives of patients, we are excited that we now have a dialyzer that can do that.”
The dialyzer uses pore-spinning technology that creates homogenous pore sizes to optimize sieving properties and improve middle molecule clearance, according to Nipro. In addition, the unique ripple structure in Elisio’s fiber creates less dialysate channeling – promoting better diffusive transport while enhancing small molecule clearances, and reducing the risk of fiber leakage.
The new polypropylene housing is also around 25% lighter than current dialyzers in the market, thus making disposal and transportation more cost effective. It also generates 25% less resin waste, and 100?C lower temperature needed to mold polypropylene parts. Polypropylene also generates 10% less CO2 emission for resin production, and 50% less CO2 emission when incinerated, Nipro said in the release.
“The eco-friendliness of the Elisio dialyzer is a definite plus,” Dawson said. “In addition, we do not have to compromise on clinical performance, while making a greener dialyzer.”
