Patents by Inventor Magnus Öhman

Magnus Öhman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7610087
    Abstract: An implantable cardiac stimulator, such as a cardioverter defibrillator, is operable in an autocapture mode. Following the delivery of a defibrillation or cardioversion shock, the stimulator switches from the autocapture mode to a post-shock mode, in which predetermined pacing pulse parameter settings are used for the delivery of pacing pulses. Following the expiration of a predetermined time interval, which may be extendable, the stimulator switches back to the autocapture mode.

  • Patent number: 7225030
    Abstract: In a method and a system for organizing not yet implanted implantable medical devices, each having a telemetry unit associated therewith, a local administration unit transmits an inquiry signal to at least one of the telemetry units and receives a return signal therefrom in response to the inquiry signal. The return signal establishes the existence of the medical device, and the local administration unit, or a remote external unit in communication with the local administration unit, can then determine a course of action to be taken, such as a recall procedure, invoicing or taking inventory, based on the return signal from the medical device.

  • Publication number: 20040116973
    Abstract: A heart stimulating device has a stimulation threshold measuring circuit for performing threshold searches by measuring a stimulation threshold value, a pulse generator for delivering stimulation pulses of variable amplitudes and duration, a control unit for controlling the pulse generator to deliver stimulation pulses of amplitudes related to the measured threshold value, an interval timer for initiating time-initiated threshold searches, wherein the time between consecutive time-initiated threshold searches is defined as a threshold search interval. The interval timer varies the threshold search interval, dependent on the result of at least the last performed threshold search.

  • Publication number: 20040002738
    Abstract: In an implantable cardioverter defibrillator capable of reducing the required energy content of defibrillation and/or cardioversion pulses, the ventricular and/or atrial capture threshold is measured, based on the measured threshold values, the value settings for the energy contents of the defibrillation and/or cardioversion pulses is increased or reduced in correspondence with variations in the measured capture thresholds.

  • Patent number: 6662114
    Abstract: A method for predicting the clinical outcome for a patient after the patient has received therapy for an acute coronary syndrome such as myocardial infarction comprises: (a) optionally, but preferably, detecting a first variable comprising a serum creatine kinase-MB release curve area in the patient after initiation of said therapy; (b) detecting a second variable comprising a serum creatine kinase-MB release curve maxima in the patient after initiation of said therapy; then (c) optionally, but preferably, detecting a third variable comprising the slope of the descending portion of the serum creatine kinase-MB release curve after initiation of said therapy (wherein a steep slope for said descending portion is a more favorable indicator of clinical outcome than a shallow slope); and (d) generating a prediction of clinical outcome for said patient from the variables collected above.

  • Patent number: 6033364
    Abstract: The present invention is a method of diagnosing the presence of a persistent occlusion in a myocardial infarct patient undergoing thrombolytic therapy. The method comprises detecting a series of five variables from the patient and then generating the probability of the presence of a persistent occlusion from those variables. The first variable comprises a serum creatine kinase MB (CK-MB) level from a patient at the onset of thrombolytic therapy. The second variable comprises a second CK-MB level in the patient at a predetermined time after the onset of thrombolytic therapy. The third variable comprises the presence or absence of chest pain a predetermined time after the onset of thrombolytic therapy. The fourth variable comprises the serum myoglobin level in the patient at a predetermined time after the onset of thrombolytic therapy.
