Abstract
An introducer includes a housing and a flexible seal. The housing includes a hub, a cap, and a lumen. The flexible seal is positioned across the lumen and retained between the hub and the cap. The seal includes a top surface and a bottom surface, a bottom slit formed in the bottom surface, and a top slit formed in the top surface. The top slit crosses the bottom slit. The seal member is biased by an interface between the hub and the cap to at least partially close the top slit and at least partially open the bottom slit.
