Systems and methods for internal ecg acquisition

An apparatus for applying a tracing to an inflatable device, comprising:

• a body having a cavity extending longitudinally within and a wall;
• one or more longitudinally extending openings in the wall and opening into the cavity, such that an inflatable device placed within the cavity it partially covered by the wall and partially uncovered by the one or more openings;
• and
• wherein the one or more openings are configured to allow the application of a conductive material to a portion of the inflatable device that is uncovered while blocking the application of the conductive material to a portion of the inflatable device that is covered by the wall.

A method for applying a conductive tracing to an inflatable device, the method comprising:

• placing an inflatable device within a body having a cavity extending longitudinally within and a wall, the body including one or more longitudinally extending openings in the wall and opening into the cavity such that the inflatable device placed within the cavity is partially covered by the wall and partially uncovered by the one or more openings;
• applying a conductive material to a portion of the inflatable device;
• and
• when the conductive material is in a condition that will not significantly change upon removal of the inflatable device from the body, removing the inflatable device from the body.
