Abstract
An access device particularly adapted for use in laparoscopic surgery facilitates access with instruments, such as the hand of the surgeon, across a body wall and into a body cavity. The device can be formed of a gel material having properties for forming a zero seal, or an instrument seal with a wide range of instrument diameters. The gel material can be translucent facilitating illumination and visualization of the surgical site through the access device.
