Distal Tip

The distal tip includes all the elements of a standard gastroscope and in addition includes the ultrasound measurement device, the anvil of the stapler and specialized screws for anchoring the scope while the procedure is performed. All this is included in a distal tip measuring only 15mm in diameter.

Procedure

The SRS is a method and apparatus for performing partial anterior fundoplication that duplicates one of the existing standard procedures for treatment of GERD, but at the same time does not require anesthesia or violation of the abdominal cavity.

1. The SRS endoscope is introduced into the stomach much like a standard gastroscope.

2. The operator selects a stapling site in the esophagus, 2.3 - 3.0 cm above the GE junction.

3. The operator inputs the distance from the incisors.

4. The endoscope is advanced into the stomach, and retroflexed to 180°.

5. It is then pulled back so that the cartridge is at the selected stapling site.

6. The endoscope is further flexed to 270°, until the tip is aligned with the cartridge.

7. The ultrasonic sight verifies that alignment is perfect and that the distance between the anvil and the tip is small enough.

8. The operator then cranks a flywheel which extrudes two tiny screws, which penetrate the tissue, and lock the anvil and cartridge together.

9. The staples are then fired, the screws are withdrawn, and the scope is extended, and withdrawn.

10. The SRS is reloaded with a new cartridge, and the procedure is repeated.

11. The final result is an antero-lateral wrap, which tapers from 120 to 180 degrees, and augments the angle of His.
