1. A surgical device comprising:
- an elongate tubular member having a bore, the bore configured for receiving a surgical instrument therethrough;
a first inflatable member disposed in a distal region of the elongate tubular member, the first inflatable member having an inflated state and a deflated state;
a collar disposed on the elongate tubular member, the collar being compressible and capable of engaging body tissue between the collar and the first inflatable member when the first inflatable member is in the inflated state;
a first port fluidly coupled to the first inflatable member; and
a second port in fluid communication with the the bore.

22. A method of accessing a space comprising the steps of:
-
making an incision through body tissue;
inserting a device through the incision, the device including;
an elongate tubular member having a bore, the bore configured for receiving a surgical instrument therethrough, a first inflatable member disposed in a distal region of the elongate tubular member, the first inflatable member having an inflated state and a deflated state, a collar disposed on the elongate tubular member, the collar being compressible and capable of engaging body tissue between the collar and the first inflatable member when the first inflatable member is in the inflated state, a first port fluidly coupled to the first inflatable member, and a second port in fluid communication with the bore; and
introducing an inflation medium to the first port such that the first inflatable member transitions from an uninflated state to an inflated state. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
