Abstract:
Disclosed herein are multiple cannulas defining a lumen sized and dimensioned to receive one or more medical instruments, an inflatable outer membrane attached to an outer surface of the cannula, and at least one activator that reversibly activates the cannulas to push a fluid contained in the cannulas into the outer membrane to fill or pressurize the outer membrane. Also disclosed are methods for operating these cannulas.

Claim (Index 1):
A cannula comprising\n a lumen wall defining at least one lumen port, a flow piston positioned on the outside of the lumen wall and defining at least one piston port, an outer casing positioned spaced apart from the flow piston to define a fluid chamber therebetween and an outer membrane connected to outer casing, wherein the outer casing defines at least one casing port to fluidly connect the outer membrane to the fluid chamber, wherein in a filling configuration the at least one lumen port aligns with the at least one piston port to allow a fluid to enter the fluid chamber and the outer membrane, and wherein in a pressurizing configuration the at least one lumen port misaligns with the at least one piston port and the flow piston is moved to move fluid from the fluid chamber to the outer membrane to secure the cannula to an incision site.
