Abstract
A needleless valve (16), which may be housed in a plastic housing (12), has a web (18) provided with a slit (20) for blunt cannula access therethrough. The web (18) is provided with a lubricious coating (22) on at least a portion thereof, the coating (22) being polymeric and covalently bonded to the web (18). Coating (22) enhances the ease of use of valve (16) and increases its useful life by decreasing the deleterious effects of repeated cannula insertion and removal.
