Willem J. A. Esmeijer 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).

  • Pulse generation techniques for implantable pulse generator systems
    Patent number: 8340762
    Abstract: The invention is directed to tri-phasic pulse generation techniques that make use of a pre-stimulus phase, a stimulus phase, and a post-stimulus phase in a pulse generation cycle. During the pre-stimulus phase, an output capacitor is charged to a desired voltage level. During the stimulus phase, the capacitor is discharged, and during the post-stimulus phase recharging of the capacitor begins again. In accordance with the invention, charging of the output capacitor can be terminated during the post-stimulus phase after a measured voltage in the patient is greater than or equal to a threshold.
    Type: Grant
