Patent attributes
A hemostasis valve for a vascular introducer includes a valve body having a seal region with opposed first and second end surfaces and a central axis extending through the seal region perpendicular to the first and second end surfaces. The first end surface of the seal region has a first grouping of cut lines formed on the first end surface and extending radially outward from the central axis. The second end surface of the seal region has a second grouping of cut lines formed on the second end surface and extending radially outward from the central axis. The first circumferential grouping of intersecting cut lines is axially aligned with and angularly offset from the second circumferential grouping of cut lines. A pair of planar slits extend angularly away from each cut line in the first end surface, through the valve body, to a respective pair of oppositely adjacent cut lines in the second end surface.
