1. A fluid remover for use in a surgical access device, comprising:
- a sorbent member having opposed proximal and distal surfaces and opposed inner and outer sidewalls extending between the proximal and distal surfaces such that the sorbent member has a polygonal cross-sectional shape, the proximal surface being substantially planar, the inner sidewall defining a central opening extending through the sorbent member, and the sorbent member including a gap formed therein such that the sorbent is C-shaped with terminal ends that substantially face each other, wherein the sorbent member is formed from a plurality of fibers that are configured to sorb fluid,wherein the plurality of fibers are oriented longitudinally relative to a longitudinal axis of the central opening.

Abstract
The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. The devices of systems can also include a fluid remover in the form of a sorbent element, a scraper element, a wicking element, or any combination thereof that is configured to remove fluid from a working channel of the device or system and/or from a surgical instrument inserted therethrough.

18. A fluid remover for use in a surgical access device, comprising:
-
a sorbent member having opposed proximal and distal surfaces and opposed inner and outer sidewalls extending between the proximal and distal surfaces such that the sorbent member has a polygonal cross-sectional shape, the proximal surface being substantially planar, the inner sidewall defining a central opening extending through the sorbent member, and the sorbent member including a gap formed therein such that the sorbent is C-shaped with terminal ends that substantially face each other, wherein the sorbent member is formed from a plurality of fibers that are configured to sorb fluid, wherein the sorbent member has a substantially triangular cross-sectional shape.
