Method and devices for stimulation of an organ with the use of a transectionally placed guide wire
View Patent ↗Devices, systems and methods are provided for electrical stimulation of a body organ, particularly within the gastrointestinal tract. In preferred embodiments, the stomach is the organ within the gastrointestinal tract which is targeted for such stimulation. A guide wire or other delivery device is positioned within the body so as to transect the stomach wall. Devices and systems are then advanced over the guide wire for attachment to the stomach wall. The guide wire may be placed by endoscopic, open, laparoscopic or a modified percutaneous approach. In a modified percutaneous approach, the stomach is accessed without the use of general anesthesia by advancing a needle through the abdomen, transecting the stomach wall with the needle and advancing the guide wire through the needle. In some embodiments, particularly for use in obese patients, the modified percutaneous approach includes advancing a trocar through the tissue of the patient toward the outer surface of the organ and advancing the needle through the trocar prior to transecting the wall with the needle.
1. A method of attaching a device having a first portion and a second portion to a wall of a hollow organ within a patient, the wall having an inner surface facing within the organ and an outer surface facing away from the organ, the method comprising:
positioning a guide wire wherein the guide wire transects the wall of the organ;
advancing the first portion of the device over the guide wire in a direction toward the inner surface of the wall of the hollow organ;
advancing the second portion of the device over the guide wire in an opposite direction toward the outer surface of the wall of the hollow organ; and
joining the first and section portions together so as to attach the device to the wall of the hollow organ.
2. The method of claim 1 , wherein positioning the guide wire comprises extending the guide wire through a mouth of the patient, and wherein advancing the first portion comprises advancing the first portion through the mouth and over the guide wire toward the inner surface of the wall of the hollow organ.
3. The method of claim 1 , wherein positioning the guide wire comprises extending the guide wire through an abdomen of the patient, and wherein advancing the second portion comprises advancing the second portion through the abdomen and over the guide wire toward the outer surface of the wall of the hollow organ.
4. The method of claim 1 , wherein positioning the guide wire comprises accessing the organ by a modified percutaneous approach without the use of general anesthesia, wherein the modified percutaneous approach comprises advancing a needle through an abdomen of the patient toward the outer surface of the organ, transecting the wall with the needle and advancing the guide wire through the needle.
5. The method of claim 4 , wherein the modified percutaneous approach includes advancing a trocar through the abdomen of the patient toward the outer surface of the organ and advancing the needle through the trocar prior to transecting the wall with the needle.
