Abstract
A hemostatic sealing assembly comprises a valve housing and a two-stage hemostatic gasket. The gasket is disposed in an enlarged recess within a shell component of the housing and held in place by a terminal plug. The front and rear faces of the gasket are conically tapered as are the mating surfaces and the housing shell and terminal plug, respectively. In this way, the gasket can be radially compressed to provide a desired degree of both sliding seal and static seal.
