First Claim
Patent Images
1. A method for attaching a device to a stomach wall of a patient comprising:
- providing an anchor comprising a first portion, an elongate portion and a device portion;
positioning the elongate portion through the stomach wall wherein the first portion engages a stomach wall on a first side of the stomach wall and so that the device portion is positioned on an opposite side of the stomach wall from the first portion;
wherein the first portion has an interfacing portion with a surface area interfacing the stomach wall and the device portion and elongate portion have a weight creating a load between the stomach wall and the interfacing portion when the elongate portion extends through the stomach wall wherein the weight has a ratio to the surface area of less than about 0.1 g/mm2;
separately deploying a stimulator in the patient;
coupling circuitry of the stimulator to the device portion of the anchor; and
stimulating the stomach wall after the stimulator is coupled to the device portion of the anchor.
