Abstract
A surgical access device includes a valve that forms a seal with a body wall and provides an access channel into a body cavity.

The valve can include a gel material and the access channel can include a protective shield to provide for wound protection during insertion and withdrawal of a sharp surgical instrument. The valve further comprises a cap ring which may be inserted or molded with the gel material.
