Abstract

The present invention provides an implantable nerve stimulation device with multiple frequency modes, including a control circuit for determining the frequency modes, the frequency modes include independent frequency modes and the same frequency mode, and multiple frequency modes are provided in the independent frequency mode Different pulse frequencies, providing a unique pulse frequency in the same frequency mode; a signal output circuit, used to output multiple groups of pulse signals according to the multiple different pulse frequencies in the independent frequency mode, wherein different groups of The pulse frequencies of the pulse signals are different. In the same frequency mode, multiple groups of pulse signals are output according to the unique pulse frequency, wherein the pulse frequencies of each group of pulse signals are the same.

Description

technical field [0001] The invention relates to the field of implantable medical devices, in particular to an implantable nerve stimulation device with multiple frequency modes. Background technique [0002] Implantable neurostimulators generally have multiple stimulation contacts and can output stimulation pulses with multiple sets of parameter combinations. Different stimulation contact combinations can be set for each group of stimulation pulses, so as to generate different stimulation signals for multiple parts. That is, multiple different parts are stimulated at the same time. [0003] In clinical application, different treatments require different numbers of stimulation sites, and the number of stimulation sites may be 2, 4, 6 or even more. Taking deep brain electrical stimulators as an example, generally at least two stimulation sites of the left and right brain are required, or two stimulation channels. In most cases, the frequencies of different stimulation parts ...
