Instrument access device
First Claim
1. A method of operating an instrument access device, including a retractor assembly, a retractor seal for positioning at a proximal portion of the retractor assembly, and an instrument valve assembly, the method comprising:
- retracting a wound opening with the retractor assembly, wherein retracting the wound opening includes;
inserting a distal member of the retractor assembly through the wound opening,positioning a retracting sleeve of the retractor assembly within the wound opening, andpositioning a proximal member of the retractor assembly external to the wound opening;
penetrating the retractor seal with the instrument valve assembly, wherein the retractor seal is unperforated prior to penetration of the retractor seal with the instrument valve assembly; and
sealing the retractor assembly for insufflation, wherein the sealing of the retractor assembly is provided, at least in part, by the instrument valve assembly.

Abstract
An instrument access device (500) comprises a distal O-ring (11) for insertion into a wound interior, a proximal member for location externally of a wound opening and a sleeve (12) extending in two layers between the distal O-ring (11) and the proximal member. The proximal member comprises an inner proximal ring member (25) and an outer proximal ring member (24) between which the sleeve (12) is led. A seal housing (300) is mounted to the inner proximal ring member (25). A gelatinous elastomeric seal (302) with a pinhole opening (303) therethrough is received in the housing (300). An instrument may be extended through the seal (302) to access the wound interior through the retracted wound opening in a sealed manner.
