Abstract
Pressure activated valves for catheters with improved tolerance of high pressure and high flow conditions are described. Embodiments of the valve comprise a flexible membrane with one or more linear slits therethrough, and means for applying tension to the flexible membrane in-line with the linear slits. The application of tension may optionally be facilitated by structural features of both the flexible membrane and the valve housing.
