It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3835865 Demand heart pacer with improved interference discrimination Cardiac pacer system and method with capture verification signal Asynchronous/demand made programmable digital cardiac pacemaker Apparatus for physiological stimulation and detection of evoked response Implantable externally programmable microprocessor-controlled tissue stimulator Electrophysiology study system using implantable cardioverter/pacer Patent #: 4705043 InventorsAssigneeApplicationNo. 06/891479 filed on 08/01/1986US Classes:607/13Reducing output recovery timeExaminersPrimary: Jaworski, Francis J.Assistant: Manuel, George Attorney, Agent or FirmInternational ClassA61N 1/365 (20060101)AbstractA pacemaker which generates a triphasic stimulus; the first and third phases are positive pulses, and the second is the negative stimulus. After-potentials are so low that reliable sensing of evoked signals are possible. The rapidity of the charge balancing is not affected by the stimulus amplitude because the relative amplitudes of the three phases are maintained independent of the stimulus amplitude. | |
