Cardiac electrode attachment procedure
First Claim
1. A surgical procedure for contacting electrodes supported on an electrode structure to the heart of a patient, the procedure comprising the steps for:
- forming a subxiphoid incision on the patient;
dissecting tissue along a tract superiorly from the subxiphoid incision to a posterior aspect of the patient'"'"'s sternum near the patient'"'"'s heart for advancing the electrode structure through the subxiphoid incision and along the tract of dissected tissue to the posterior aspect of the patient'"'"'s sternum; and
positioning the electrode structure within the region posterior to the posterior aspect of the patient'"'"'s sternum and anterior to the patient'"'"'s heart to form contact therewith of a number of the electrodes of the electrode structure.

Abstract
Surgical procedure and surgical instruments include an electrode structure for insertion through tissue superiorly of a subxiphoid incision to a position posterior of an aspect of the sternum and anterior of the pericardium. The electrode structure may be expanded, for example, including an inflatable member to position a number of electrodes of the electrode structure in contact with the pericardium. Alternatively, an electrode structure on an insertion cannula may be retained in contact with the pericardium by the cannula positioned within the dissected tissue. Electrical conductors from the contacting electrodes are routed through the tract of dissected tissue toward the subxiphoid incision for attachment to a generator that is implanted in a subcutaneous pocket near the subxiphoid incision.
