The first ring (14) is formed by combining a first material having a first durometer and a second material having a second durometer. Alternatively, a flexible sealing ring (90) for use with a surgical retractor (10) to prevent cross-contamination during surgery of fluids and solids is presented, the ring (90) composed of at least two materials, the first material having a first durometer (92) and the second material having a second durometer (94), where the first durometer (92) is greater than the second durometer (94). 5785689-1: EEB1/5 9 Fig. -.-r 3A 3A Fig. 2A
