摘要： A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending there through. Embodiments of the instrument contact element comprise a non- distensible membrane or film, for example, as a tube or cylinder. Some embodiments of the instrument contact element have an hourglass configuration with a first end proximal of the opening of the compression element and a second end distal of the opening of the compression element. Other embodiments of the instrument contact element "wrap around" the opening in the compression element, with the first end and the second end secured to the same side of the opening, for example, proximal of the opening. Embodiments of the compression element comprise an elastomeric seal, for example, a septum seal and/or a gel seal.
