Abstract
A hemostasis valve for a vascular introducer includes a valve body having a seal region with opposed substantially planar proximal and distal end surfaces and a central axis extending through the seal region perpendicular to the proximal and distal end surfaces. The seal region has a first grouping of circumferentially arranged and equidistantly spaced linear cuts extending radially outward from the central axis, and through the seal region from the proximal end surface to the distal end surface. The seal region has a second grouping of circumferentially arranged and equidistantly spaced linear cuts in the distal end surface extending tangentially outward from the first grouping of linear cuts, and partially from the distal end surface to a depth short of the proximal end surface to facilitate passage of a variety of sizes of medical devices through the seal region.
