PROBLEM TO BE SOLVED: To solve the problem that minimally invasive procedures are complicated by a number of visual limitations, in particular, the surgeon's view is limited to what is directly in front of and is illuminated by a scope inserted in the incision, to inhibit damage to internal body structures, and to illuminate the surgeon's viewing field to a greater degree than is currently possible. SOLUTION: A seal anchor member inludes a housing that includes leading and trailing ends, an intermediate portion positioned between the leading and trailing ends and adapted to be positioned within the tissue tract in a substantially sealed relation with tissue surfaces that define the tissue tract, at least one longitudinal port extending between the leading and trailing ends, and adapted to receive an instrument therein in a substantially sealed relation, and at least one light source operatively associated with the leading end.
