Methods and devices are provided for various insufflation sealing approaches for a trocar. For example, a trocar is provided that has a housing and a cannula extending therefrom. The housing and the cannula have a tool pathway extending therethrough for receiving a surgical tool, and the housing has an insufflation port therein.

The port and seal elements are configured to have a reduced profile to prevent interference between the trocar and a tissue surface during use.
