Abstract

A surgical access device and methods for facilitating access through an incision or wound to a surgical site in a patient's body comprising an inferior retention member, a superior retention member, and a pliable membrane therebetween. The pliable membrane includes a base layer, a permeable membrane attached to the base layer, and a fluid delivery region disposed between the layers. The fluid delivery region is fluidly coupled to a fluid source. The fluid is delivered to the surgical site via the permeable membrane. The inferior retention member provides for fluid removal from the surgical site. Methods are provided for use of the surgical access device to retract tissue and deliver fluid to the tissue from the pliable membrane.
