Abstract

A surgical access device includes an access seal comprising an ultra gel elastomeric material formed of a mixture comprising a triblock copolymer and an oil. The access seal is adapted to be disposed relative to the abdominal wall. At least one access channel is formed through the elastomeric material between a proximal portion and a distal portion of the access seal. The access channel when operatively disposed forms at least a portion of a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The elastomeric material of the access seal is adapted to conform to a surface of an instrument inserted through the working channel to provide instrument access to the abdominal cavity while maintaining insufflation pressure in the abdominal cavity. The access channel is configured to self seal in the absence of any instrument extending through the access channel.
