Abstract
A hemostasis valve membrane for use with a catheter introducer having a cover and a frame is disclosed. The valve membrane is inserted between the cover and the frame of the catheter introducer body. The valve membrane is a disc made of a soft elastic material. The disc has opposed faces, at least one of which has a concave shape extending into the disc. A plurality of slits extend into the disc from the faces so that slits extending into the disc from one face do not touch slits extending into the disc from the opposed face. A needle hole connects the slits extending into the disc from one face with the slits extending into the disc from the opposed face.
