Rahul Mehra: Implantable electrode for location within a blood vessel. Medtronic, Reed A Duthler, Harold R Patton, December 15, 1992: US05170802 (350 worldwide citation)

An expandable electrode for location within a blood vessel or other tubular organ. The electrode takes the form of a hollow, tubular metal structure, expanded into contact with the inner walls of the tubular structure in which the electrode is to be located. Expansion of the electrode may take place ...

Rahul Mehra, William Combs: Method of defibrillating a heart. Medtronic, Joseph F Breimayer, Reed A Duthler, September 4, 1990: US04953551 (301 worldwide citation)

A method of terminating ventricular fibrillation by the delivery of an asymmetric biphasic current pulse to three separate electrodes. A first catheter mounted electrode is located in the apex of the right ventricle (RV). A second electrode carried on the same catheter is located outside the atrium ...

Rahul Mehra: Method and apparatus for discrimination of ventricular and supraventricular tachycardia. Medtronic, Reed A Duthler, Harold R Patton, September 14, 1993: US05243980 (298 worldwide citation)

A method for discrimination between ventricular and supraventricular tachycardia and an apparatus for performing the method. In response to the detection of the occurrence of an tachycardia, stimulus pulses are delivered to one or both of the SA and AV nodal fat pads. The response of the heart rhyth ...

David E Francischelli, Mark T Stewart, James R Skarda, Rahul Mehra: Ablation system and method of use. Medtronic, Thomas G Barry, Daniel M Lathan, November 18, 2003: US06648883 (271 worldwide citation)

A system and method for creating lesions and assessing their completeness or transmurality. Assessment of transmurality of a lesion is accomplished by monitoring the impedance of the tissue to be ablated. Rather than attempting to detect a desired drop or a desired increase impedance, completeness o ...

Michael R S Hill, Rahul Mehra: Method and apparatus for control of A-V interval. Medtronic, Reed A Duthler, Harold R Patton, April 16, 1996: US05507784 (257 worldwide citation)

A device for controlling the duration of A-V conduction intervals ia a patient's heart. Stimulation of the AV nodal fat pad is employed to maintain the durations of the A-V conduction intervals within a desired interval range, which may vary as a function of sensed heart rate or other physiologic pa ...
