  • Publication number: 20120089161
    Abstract: The present disclosure relates to a seal assembly for a cannula. The cannula includes a housing having a proximal portion and a distal portion. The seal assembly is located in the proximal portion of the housing and includes a first seal including a first tri-slit, a second seal disposed co-axially and proximal to the first seal and including a second tri-slit, and a third seal disposed co-axially to the first seal and the second seal and including a central opening. A cap is coupled to the proximal portion of the housing and adjacent the third seal and includes a plurality of suture retaining features, such as tabs, for management of sutures during surgery. Fluid leakage out of the cannula, during surgery, is substantially reduced due to the leakage being limited to a channel defined by the first tri-slit, the second tri-slit, and the central opening.
