Abstract:
1. A valve for a hub of a sheath, catheter, or other tubular device, comprising: a valve body comprising an inlet end, an outlet end, a central longitudinal axis extending between the inlet and outlet ends, and an outer surface extending from the outlet end at least partially towards the inlet end; a bore extending partially through the valve body from the inlet end towards the outlet end; and a slit extending transversely through the valve body from a first side of the outer surface partially towards an opposite second side of the outer surface, thereby defining a cover in the valve body located between the bore and the outlet end, the cover biased to close the bore and resiliently flexible to open to accommodate an instrument introduced through the bore from the inlet end, wherein the valve body includes a pair of stops extending from the outer surface adjacent the second side for supporting the cover adjacent a base of the slit, and wherein the stops include stop surfaces defining an acute angle with the outer surface adjacent the base of the slit such that the stops resist propagation of the slit to the second side of the outer surface.
