The electrode is inserted into the diaphragm, at an angle so that the electrode lead
travels parallel to the plane of the diaphragm prior to exit, and the delivery
instrument is withdrawn. A standard laparoscopic dissector may be used to assist
in the positioning of the electrode at the desired site on the diaphragm and give
counter-traction when the needle is being removed. The electrode is then tested
to assure the desired response to twitch stimuli is achieved and the procedure is
repeated for the remaining electrodes. If the response is not adequate when tested
the electrode may be withdrawn and another implanted. A second electrode is
implanted at the previously marked site during mapping. At the conclusion of the
implantation a CXR will be obtained to be sure no intra-abdominal air will have
tracked with the needle to the chest cavity- a capnothorax. If one is present it can
be aspirated with a percutaneous catheter (such as an angiocatheter, small chest
tube, or thoracentesis) at the end of the case.
Electrode Insertion
Once all four electrodes are implanted they are brought out through the epigastric
trocar location.
