ABSTRACT:
A self-sealing hemostatic valve for use in a catheter apparatus is disclosed, comprising a proximal valve element having a sealing hole, a distal valve element having a flap and biasing means to enhance the force with which the flap bears against the distal side of the proximal valve element to normally seal the hole. The sealing hole seals about an instrument passed through the valve and the flap seals the valve when no instrument is present. The proximal face of the proximal valve element is provided with discontinuities that increase the flexibility of the proximal valve element in a distal direction.
