Abstract

A method for creating a plication within a hollow organ. The method uses an elongated member having an end effector attached to its distal end. The end effector has a substantially hollow housing, a fixed jaw extending distally from the housing, and a retractable jaw located within the housing. The method involves the step of inserting the end effector within an organ of a patient such that it is in contact with tissue. The method also involves applying vacuum through the elongated member so as to dispose tissue on the fixed jaw and at least partially within the housing. The method also involves creating a plication by sliding the retractable jaw so that it juxtaposes the fixed jaw.

Claims

1. A method for creating a plication within a hollow organ, said method comprising the steps of:

a. providing an elongated member having an end effector attached to an open distal end thereof, said end effector comprising a substantially hollow housing, a fixed jaw extending distally from said housing, and a retractable jaw located within said housing, said end effector having an open distal tip;

b. inserting said end effector within the organ of a patient such that said open distal tip is in contact with tissue;

c. applying vacuum through said elongated member and disposing tissue on said fixed jaw in a direction from a distal of said fixed jaw towards a proximal end of said fixed jaw, so that said tissue is at least partially within said housing;

d. creating a plication by sliding said retractable jaw so that it juxtaposes said fixed jaw.

2. The method of claim 1 further comprising the step of inserting a visualization means within said organ.

3. The method of claim 1 further comprising the step of sterilizing said device after step (d).

4. The method of claim 1 further including the step of applying a fastening means to said tissue after step (d).
