Abstract
A surgical access device is disclosed which includes a housing, a collar, and a plurality of deformable members. The housing defines a proximal end and a distal end and has a plurality of lumens extending therethrough. The collar is repositionable between a first position and a second position with the second position being closer to the proximal end of the housing than the first position. Each of the plurality of deformable members defines a distal portion, is coupled to the collar and is transitionable through one of the plurality of lumens. The plurality of deformable members is in a retracted state when the collar is in the first position and a deployed state when the collar is in the second position. One or more of the plurality of deformable members may also include a barb attached to the distal portion.
