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 has properties for creating a zero seal in the absence of an instrument as well as an instrument seal for an instrument. 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.

9. A surgical access device facilitating a sealing relationship with a surgical instrument extending through the device and into patient, the surgical access device, comprising:
-
a cap ring surrounding a seal forming a zero seal in the absence of the instrument extending through the seal and forming a seal with the instrument in the presence of the instrument extending through the seal; and a protective shield positioned circumferentially around an inner diameter of the cap ring and extendable into the patient, the protective shield having a proximal end with a decreasing taper to a middle portion of the protective shield and having a distal end with an increasing tapered from and away from the middle portion of the protective shield and the protective shield having a fixed nonadjustable length. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
