Claim Text:
1. An introducer sheath, comprising: a hub having a proximal end and a distal end and a lumen extending therebetween and a flexible valve member disposed in the proximal end of the hub, the flexible valve member having an aperture configured to receive a medical device, the flexible valve member having a proximal surface and a distal surface, both the proximal surface and the distal surface of the flexible valve member being transverse to a lateral plane through a longitudinal axis of the hub and both being non-planar in a relaxed state prior to insertion into the introducer sheath and planar in a retracted state within the introducer sheath, the non-planar profiles of the proximal surface and the distal surface being parallel in the relaxed state and the planar profiles of the proximal surface and the distal surface in the retracted state being parallel, and wherein the aperture has a substantially conical shape in the relaxed state and a substantially cylindrical shape in the retracted state; and an elongated tubular member having a proximal end and a distal end.
