    • An implantable device for evaluating autonomic cardiovascular drive in a patient suffering from chronic cardiac dysfunction is provided. A stimulation therapy lead includes helical electrodes configured to conform to an outer diameter of a cervical vagus nerve sheath, and a set of connector pins electrically connected to the helical electrodes. A neurostimulator includes an electrical receptacle into which the connector pins are securely and electrically coupled. The neurostimulator also includes a pulse generator configured to therapeutically stimulate the vagus nerve through the helical electrodes in alternating cycles of stimuli application and stimuli inhibition that are tuned to both efferently activate the heart's intrinsic nervous system and afferently activate the patient's central reflexes by triggering bi-directional action potentials. The neurostimulator includes a recordable memory storing a baseline heart rate. The neurostimulator includes an integrated leadless heart rate sensor configured to continually monitor heart rate in light of the baseline heart rate.

    • In some examples, relatively low frequency (e.g., less than about 50 Hertz) electrical stimulation therapy is delivered to a target tissue site proximate to one or more of the T9, T10, T11, T12, L1, L2, or L3 (“T9-L3”) spinal nerves of a patient to manage a pelvic floor disorder, such as urinary retention, fecal retention, or both. The relatively low frequency electrical stimulation therapy is configured to excite the one or more of the T9-L3 spinal nerves, which may generate an activating response from the patient related to voiding and help promote voiding by the patient. For example, the low frequency electrical stimulation may be configured to help improve the patient's pelvic sensations, which may help the patient better control urination.
    • 在一些示例中,相对低频率(例如,小于约50赫兹)的电刺激治疗被递送到靠近T9,T10,T11,T12,L1,L2或L3中的一个或多个的靶组织位点(“T9 -L3“)脊髓神经来治疗盆底疾病,例如尿潴留,粪便保留或两者。 相对低频的电刺激治疗被配置为激发一个或多个T9-L3脊神经,其可以产生患者与排尿相关的激活反应并且有助于促进患者的排尿。 例如,低频电刺激可以被配置为帮助改善患者的盆腔感觉,这可以帮助患者更好地控制排尿。
