    • A neurostimulation system for management of stimulation safety limits. The system determines a tissue charge injection metric at each electrode, compares the metric to the hard stop charge limit, and prevents the neurostimulator from delivering stimulation energy to the tissue region in accordance based on the comparison. The hard stop limit may be user-programmable or may be automatically modified in response to detection of electrode characteristics. The system may quantitatively notify a user of a value of the injected charge injected into the tissue. The electrodes may be organized into different sets, in which case, the system may directly control tissue charge independently at each of the electrode sets. If current steering is provided, the system may displace the electrical stimulation energy along the tissue region in one direction, while preventing the charge injection value at each of the electrodes from meeting or exceeding the hard stop charge limit.
    • 用于管理刺激安全限值的神经刺激系统。 系统确定每个电极处的组织电荷注入度量,将该度量与硬停止电荷限制进行比较,并且根据比较来防止神经刺激器将刺激能量递送至组织区域。 硬停止极限可以是用户可编程的,或者可以响应于电极特性的检测而被自动修改。 该系统可以定量地向使用者通知注入到组织中的注入电荷的值。 电极可以组织成不同的组,在这种情况下,系统可以在每个电极组中独立地直接控制组织电荷。 如果提供电流转向,则系统可以沿着一个方向沿着组织区域移位电刺激能量,同时防止每个电极处的电荷注入值达到或超过硬停止充电极限。
