1. A surgical access device, comprising:

  • a proximal housing, a distal cannula, and a working channel extending through the proximal housing and the distal cannula that is sized and configured to receive a surgical instrument;

    a seal disposed within the proximal housing configured to seal the working channel when no surgical instrument is disposed therethrough, the seal having an opening extending therethrough and positioned to receive a surgical instrument passed through the working channel; and

    a fluid remover positioned distal of the seal, the fluid remover having an opening extending therethrough and positioned to receive a surgical instrument passed through the working channel, and the fluid remover being configured such that, when an instrument occludes the opening in the fluid remover, the fluid remover allows insufflation gas to pass between a proximal side of the fluid remover and the distal cannula to thereby equalize a pressure on proximal and distal sides of the fluid remover.
