Abstract

An improved access assembly is provided. The access assembly includes an inflatable port and an inflation cannula operably connected to the inflatable port to provide inflation fluid to the inflatable port. The inflatable port may be tapered in a first configuration to facilitate insertion through tissue. The inflation port defines a substantially hour-glass shape when in a second configuration to create a seal within an opening in the tissue.

Claims

1. A method of accessing a body cavity comprising:

providing an access assembly including an inflatable port and a rigid inflation cannula fixedly received within the inflatable port, wherein the inflatable port is transitionable between a tapered configuration to facilitate reception of the access assembly through tissue and an hour-glass configuration to maintain the access assembly within tissue;

inserting the access assembly through tissue when the inflatable port is in the tapered configuration;

securing the access assembly within the tissue by inflating the inflatable port to the hour-glass configuration; and

performing a procedure through the inflatable port.

2. The method of claim 1, further including deflating the inflatable port and removing the inflatable port from the tissue.

3. The method of claim 1, further including creating an incision in the tissue.

4. The method of claim 1, wherein the rigid inflation cannula includes a piercing tip.

5. The method of claim 1, further including connecting the rigid inflation cannula with a source of inflation fluid.

6. The method of claim 5, further including disconnecting the rigid inflation cannula from the source of inflation fluid once the inflatable port is sufficiently inflated.

7. The method of claim 1, further including transitioning the inflatable port to the tapered configuration.

8. The method of claim 7, wherein transitioning the inflatable port to the taper configuration includes wrapping the inflatable port about the rigid inflation cannula.

9. The method of claim 4, wherein inserting the access assembly through tissue includes piercing the tissue with the piercing tip of the rigid inflation cannula.

10. The method of claim 1, wherein the inflatable port includes a plurality of lumens for receiving instruments in a sealing manner, wherein performing a procedure through the inflatable port includes receiving instruments through the plurality of lumens.

11. The method of claim 1, wherein the rigid inflation cannula extends through the inflation port.

12. A method of accessing a body cavity comprising:

providing an access assembly including an inflation cannula having a sharpened tip and an inflatable port securely affixed to the inflation cannula, wherein the inflatable port is transitionable between a deflated configuration to facilitate reception of the access assembly through tissue and an inflated configuration to maintain the access assembly within tissue;

inserting the access assembly through tissue when the inflatable port is in the deflated configuration by piercing the tissue with the sharpened tip of the inflation cannula;

inflating the inflatable port; and

performing a procedure through the inflatable port.

13. The method claim 12, further including wrapping the inflatable port around the inflation cannula when the inflatable port is in the deflated configuration to facilitate inserting the access assembly through tissue.

14. The method of claim 12, wherein the sharpened tip of the inflation cannula extends beyond the inflatable port when the inflatable port is in the deflated configuration.
