1. A valve for sealing a hub of a sheath assembly, the valve comprising:
a valve body with a thickness between a proximal surface and a distal surface,
the valve body including a bisecting slot extending into and across the proximal surface of the valve body and terminating at a depth less than the thickness of the valve body such that a remaining portion of the valve body distal of the slot defines a bridge extending between opposed halves of the valve body such that the distal surface of the valve body is substantially continuous;
wherein the bridge includes a central bridging portion and an outer bridging portion with a central thickness of the central bridging portion being larger than an outer bridging portion thickness of the outer bridging portion and wherein the bridge has a thickness under the bisecting slot that increases from the outer bridging portion to the central bridging portion; and,
wherein a central portion of the proximal surface of the valve body is concave and defines a concave proximal portion.
