Pittsburgh, US - Bayer MaterialScience llc has recently developed a new range of hydrophilic coatings, based on polyurethane technology, the company said 16 June.
The new coatings, available in two separate formulations - aqueous polyurethane dispersions and solvent-borne polyurethane solutions, are custom designed for the medical industry and offer low swelling compared with competing products, the company said.
Hydrophilic coatings are used in a range of medical devices, including catheters, guidewires, introducers, leads and endoscopes. BMS said use of hydrophilic polyurethane coatings may give hemocompatibility "above and beyond" that typically seen with polyurethane.
Paul Nowatzki, associate scientist at BMS said the coatings are "uniquely strong and durable," making them promising for medical device applications where other coatings fail under stress. (RD)
