Abstract

The present invention is a method for accessing the abdominal cavity of a patient in order to perform a medical procedure therein. The method can include the steps of introducing a medical device into the body cavity; providing a percutaneous incision to access the body cavity; and steering the medical device through the percutaneous incision. In one embodiment, a hollow steering element is advanced through the incision to guide a flexible endoscope postioned in the abdominal cavity.

Claims

1. A method for accessing a body cavity, the method comprising:

introducing a medical device into the body cavity;

providing a percutaneous incision to access the body cavity;

steering the medical device through the percutaneous incision;

wherein the step of steering comprises extending a steering element through the percutaneous incision to manipulate a portion of the medical device.

2. The method of claim 1 wherein the step of introducing comprises introducing the medical device through a naturally occurring body orifice.

3. The method of claim 1 wherein the step of introducing a medical device comprises introducing a flexible endoscope.

4. The method of claim 1 wherein the step of introducing the medical device comprises introducing the medical device into the upper gastrointestinal tract and through a gastric opening into the abdominal cavity.

5. The method of claim 1 wherein the step of steering the medical device comprises steering the distal end of an endoscope positioned in the abdominal cavity.

6. The method of claim 1 wherein the steering element is hollow.

7. The method of claim 6 communicating a vacuum source with said hollow steering element.

8. The method of claim 6 comprising extending a tether through said hollow steering element.

9. A method for accessing a body cavity, the method comprising:

introducing a medical device transorally into the gastrointestinal tract;

providing an opening communicating from inside the gastrointestinal tract to the body cavity;

directing a portion of the medical device into the body cavity through the opening communicating from inside the gastrointestinal tract to the body cavity;

providing an incision communicating from outside the body to the body cavity; and

manipulating a portion of the medical device disposed in the body cavity through the incision.

10. The method of claim 9 wherein the step of providing an opening communicating from inside the gastrointestinal tract to the body cavity comprises providing an opening in the wall of the stomach.

11. The method of claim 10 further comprising providing a seal at the opening in the wall of the stomach.

12. The method of claim 9 wherein the step of steering comprises extending a steering element through the incision to manipulate a portion of the medical instrument.

13. The method of claim 9 wherein the step of providing the incision communicating from outside the body cavity comprises forming the incision from outside the body.

14. A method for accessing a body cavity, the method comprising:

providing an opening through the wall of the stomach into the abdominal cavity;

providing an incision through the abdominal wall into the abdominal cavity;

introducing a medical device transorally into the stomach;

directing a distal portion of the medical device through the opening in the wall of the stomach to be disposed In the abdominal cavity; and

manipulating tho distal portion of the medical device disposed in the abdominal cavity through the incision through the abdominal wall.
