Abstract
Seal assemblies, generally for use in trocar assemblies, are provided for selectively promoting movement of fluid away from a central portion of the seal assemblies. In one exemplary embodiment, an inner surface of a seal body of the seal assembly is configured to selectively promote such movement of fluid away from the central portion of the seal body toward a peripheral portion of the seal body. While various configurations, geometries, and dimensions are discussed, one example of such a configuration includes locating a central portion of the seal body at a more proximal position than a peripheral portion of the seal body.
