Claim Text:
1. A valve housing having a longitudinal axis comprising: a first housing including a first lumen extending therethrough, the first housing including a first disk facing surface, the first disk facing surface having a first disk contacting surface located radially from a first point along the longitudinal axis, and a second disk contacting surface located radially from a second point along the longitudinal axis, wherein the first point is location radially outward relative to the second point; a second housing including a second lumen extending therethrough, the second housing including a second disk facing surface, the second disk facing surface including an outer perimeter and a protrusion, a portion of the space between the outer perimeter of the second disk facing surface and the protrusion defining a relief well; a flexible disk including at least one slit extending therethrough, the at least one slit intersecting a third point along the longitudinal axis, the flexible disk including a first surface facing the first disk facing surface of the first housing and a second surface facing the second disk facing surface of the second housing, at least a portion of the second surface of the flexible disk is compressed by the protrusion of the second disk facing surface to deform a portion of the flexible disk therein, at least a portion second surface of the flexible disk that is not compressed by the protrusion of the second disk facing surface extends into the relief well; and wherein the first point is located axially distal from the third point, and the second point is located axially distal to the third point, the first disk contacting surface extending proximally away at an angle from an opening within the first lumen along the longitudinal axis, the second disk contacting surface is located radially outward from and at a different angle relative to the first disk contacting surface.
