Abstract
A system for obtaining signals related to electrical activity of the heart of a subject includes a sensing device including an elongate member having a distal end configured for placement within a body lumen of a subject, and a proximal end configured to extend from the subject, an actuation portion carried by the elongate member and configured for placement within the body lumen, the actuation portion having a low-profile state for delivery within the body lumen and an expanded state, and one or more sensors disposed on the actuation portion, each including a contact surface configured to contact an interior wall of the body lumen, wherein the actuation portion is configured to cause the contact surface of each of the one or more sensors to contact a location on the interior wall of the body lumen to provide a signal component for producing one or more electrocardiogram signals.

6. A method for applying a conductive tracing to an inflatable device, the method comprising:
-
placing an inflatable device within a masking fixture having a cavity extending longitudinally therein and a wall, the inflatable device comprising an elongate shaft having a proximal end and a distal end and an inflatable portion carried by the distal end of the elongate shaft, the masking fixture including two or more longitudinally extending openings through the wall and into the cavity such that the inflatable device placed within the cavity is partially covered by the wall and partially uncovered by the two or more openings, wherein each of the two or more openings are separated from each other; applying a conductive material to an uncovered portion of the inflatable device at a first and second of the two or more openings; and when the conductive material is in a condition that will not significantly change upon removal of the inflatable device from the masking fixture, removing the inflatable device from the masking fixture, such that the inflatable device includes separate first and second conductive traces formed thereon, wherein each of the first and second conductive traces is located at a different rotational orientation than the other of the first and second conductive traces. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
