device 10 can be designed to yield a required force the area of the occlusion device 10 may also be appropriately designed to spread out the force in order to minimize the compression of the tissue other forces may be similarly determined for different geometries and areas under consideration fig4 shows a flow chart of a method 100 for reducing the size of an esophageal hiatus by employing the occlusion device 10 for ease of understanding the steps of the related methods described herein will be discussed relative to the components of the occlusion device 10 shown in fig1 and 2 but it will be appreciated by one skilled in the art that any such device can be used to perform these methods so long as the device is capable of magnetically engaging a magnetic composition through a piece of tissue such that the engagement is secure at step 102 the first and second magnetic components 12 14 are inserted laparoscopically into the patient 39 s body in this embodiment and the embodiment where the occlusion device 10 comprises a single flexible magnetic component the magnetic component s may be inserted through a catheter into the patient 39 s abdominal cavity at step 104 the first and second magnetic components 12 14 are positioned adjacent and parallel to the inferior surface of the diaphragm 52 downward tension is applied to the edges of the enlarged portion of the esophageal hiatus.
