Each tip electrode (31) is separated from another tip electrode (31) by insulation (32). A cup electrode (33) is electrically connected to an associated electrode lead wire (19) and defines a cavity (50) shaped to overlap the margin (40) of the composite electrode (30). The cup electrode (33) is fixedly secured to the composite electrode (30) and to a distal end of the elongated body (11) and is separated from the composite electrode (30) by insulation (32).

    Abstract: A probe (110) useful for invasively monitoring the oxygen saturation level of blood in the tissue walls of an anatomical cavity, for example in the esophagus, rectum or vaginal cavity of a human patient. The probe (110) may also be suitably employed in many veterinary applications. The probe (110) generally comprises a chassis (112) with an electrical connector extending from the proximal end of the chassis and terminating at a plug (132) configured for connection to a pulse oximeter box. The probe (110) further includes an optics assembly (126, 128) configured for either reflective or transmissive optics and configured to generate and transmit electrical signals that are indicative of the dynamic oxygen saturation level of blood in the wall tissue. In a further embodiment of the invention, the probe (110) may include a deployment device (119) attached to the chassis (112), for biasing the optics assembly (126, 128) into the tissue wall of the anatomical canal. The deployment device (118) may be, for example, a spring, a balloon or any other biasing device which urges the optics assembly into the wall tissue of the anatomical cavity. Further, the oximetry sensing assembly may be configured as part of an esophageal stethoscope having other sensing devices, for example, a temperature sensor (122), a pacing assembly (135), and an acoustic monitor (124).

    Abstract: Systems (10) for examining heart tissue morphology deploy one or more electrodes (38) into the heart in contact with endocardial tissue. The systems transmit electrical current from the electrodes (38) in paths through the contacted endocardial tissue. Based upon these current transmissions, the systems derive the electrical characteristics of tissue lying in the path. This electrical characteristc can be directly correlated to tissue morphology. The systems maximize surface contact with endocardial tissue, while minimizing contact with the surrounding blood pool, to obtain accurate tissue electrical characteristic measurements.
