| titleOfInvention | Apparatus for pacing an in vivo heart |
| abstract | The apparatus comprises a probe (60) having a tip (64) portion, a first electrode (72) mounted on a terminal free end of the tip portion (64) and a second electrode (74) spaced along the tip portion (64) from the first electrode (72) for supplying a reference potential. The probe (60) is constructed so as to hold the first electrode (72) in contact with tissue of an in vivo beating heart with a positive pressure without causing macroscopic damage to the heart tissue while orienting the probe such that the second electrode (74) is spaced from the heart tissue. A stylet (66) is retractably mounted within the probe, for allowing a physician to maneuver the probe (60) through a vein or the like. Once the probe (60) is in position, it may be replaced by a probe of a different shape. The probe (60) may also be retracted while being inserted, for preventing internal injury to the patient. The stylet (66) may have a noncircular cross-section for restricting directions in which it can bend. In an alternative embodiment, a combination catheter (200) is disclosed, including pacing electrodes (210, 220) for pacing the heart while measuring the potentials thereof. The pacing electrodes (210, 220) of this embodiment are placed near the tip of the catheter, and circumferentially displaced from one another to form an electric dipole for pacing the heart, and in addition are relatively small, to minimize the potential threshold necessary to pace the heart. Such pacing electrodes (210, 220) may be used without the first and second electrodes for measuring potentials. |
