Hydrogel Cote queuing containing urea polymer hydrogel - at least one polyurethane which is mixed with other different polymer hydrogel

摘要

(57) and polyurethane metal substrate or rubber substrate or polymer plastic and hydrophilic coating composition, smooth polyurethane / urea prepolymer addition intermediate that has been mixed with a hydrogel polymer precursor at least one different [summary] / urea prepolymer added intermediate and substance consists a smooth hydrogel Cote queuing hydrogel at least one different, are firmly adhered to the substrate coating composition is over it is disclosed. Medical devices and is a Nama-sho tolerable and, substance coating composition of these and have been coated is ideally suited for use stent catheter, catheter and balloon, the above particular are non-toxic. I show a high degree of wear performance in long-term use of the device as well as a low coefficient of friction in the contact body fluids, devices that are coated and materials, coating compositions thereof, are coated with the blood, in particular. It can be reactivated immediately for subsequent use by exposure to water, and can increase the storage of the device as they apply by drying the hydrogel Cote Ing.
