Devices and methods are provided for removing fluid from a surgical access device and/or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, in one embodiment, an exemplary device can include a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriented to direct gas, such as air or an insufflation gas, into the working channel so as to remove fluid on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to help prevent fluid from accumulating on the surgical access device and/or surgical instruments.

1. A surgical access device, comprising: a body defining a working channel configured and sized to allow for passage of a surgical instrument therethrough, wherein the body has a proximal housing and a distal cannula;a seal extending across the working channel so as to contact a surgical instrument inserted therethrough;at least one inlet formed through a sidewall of the proximal housing and configured to receive gas flow from an insufflation port; anda plurality of outlets formed through an internal sidewall of the proximal housing at a location distal to the seal, the plurality of outlets being configured to receive gas flow from the inlet through at least one internal channel separate from the working channel and extending between the at least one inlet and the plurality of outlets and to deliver gas flow to the working channel, the plurality of outlets being oriented to direct gas flow towards the seal in the working channel for removing fluid on the seal, and the plurality of outlets being positioned a distance from a central longitudinal axis of the working channel, the distance being greater than a maximum radius of the cannula. 2. The surgical access device of claim 1, wherein the body includes a proximal housing and a distal cannula extending from the housing and configured to be inserted into a body cavity. 3. The surgical access device of claim 2, wherein the seal and the plurality of outlets are disposed in the proximal housing. 4. The surgical access device of claim 1, wherein the seal is at least one of a multi-layer seal, a duckbill seal, a flapper seal, an annular seal, a zero-closure seal, a seal with a slit-shaped opening, a universal seal, an O-ring, a diaphragm seal, and a gel seal. 5. The surgical access device of claim 1, wherein the plurality of outlets have tapered nozzles to focus gas flowing therefrom towards the seal. 6. The surgical access device of claim 1, wherein the seal has an opening formed therein and the plurality of outlets are oriented so as to direct gas toward the opening. 7. The surgical access device of claim 1, wherein the seal has a slit-shaped opening formed therein, and the plurality of outlets are configured to direct gas in one of a substantially perpendicular or parallel direction to the opening. 8. The surgical access device of claim 1, further comprising a valve element associated with the plurality of outlets to control gas flow therethrough. 9. The surgical access device of claim 8, wherein the valve element is coupled to a control device that provides signals to control gas flow through the valve element. 10. The surgical access device of claim 1, further comprising an exhaust port coupled to at least one of the working channel and the plurality of outlets. 11. The surgical access device of claim 1, wherein the plurality of outlets are oriented to direct gas flow against, across, or around the seal in the working channel. 12. The surgical access device of claim 1, wherein the plurality of outlets are disposed circumferentially around the seal in the working channel. 13. A surgical access device, comprising: a body having a proximal end and a distal end and defining a working channel configured and sized to allow for passage of a surgical instrument therethrough;a valve extending at least partially across the working channel and configured to form a seal across the working channel when no instrument is disposed therethrough;a seal extending at least partially across the working channel and configured to contact and form a seal around a surgical instrument inserted therethrough;an inlet extending into an outer sidewall of the body; anda plurality of outlets formed in an internal sidewall of the body distal to the seal and configured to receive gas flow delivered into the inlet through at least one internal channel separate from the working channel and extending between the at least one inlet and the plurality of outlets, the plurality of outlets being oriented in a proximal direction to direct gas flow proximally towards the seal in the working channel for removing fluid on the seal. 14. The surgical access device of claim 13, wherein the plurality of outlets are oriented to direct gas flow against, across, or around the seal in the working channel. 15. The surgical access device of claim 13, wherein the plurality of outlets are disposed circumferentially around the seal in the working channel.
