Abstract
Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a proximal end region. A cartridge may be at least partially disposed within the proximal end region. The cartridge may include a seal member. The seal member may be designed to shift between an open configuration and a sealed configuration. A plunger, having an inner tubular region and a distal end, may be coupled to the proximal end region of the main body. The distal end of the inner tubular region may be spaced a clearance distance from a proximal end of the seal member so that when the seal member is in the sealed configuration and exposed to pressures of 80-250 pounds per square inch, the seal member deflects into contact with the distal end of the inner tubular region and remains in the sealed configuration.
