  • Publication number: 20240050746
    Abstract: The present invention relates to systems and methods for improvement of physiological function in an individual with a spinal cord injury via electrical stimulation of the spinal cord. A 3D model of the spinal cord is used to determine an initial position for an electrode array to deliver stimulation. Spinal cord electrical stimulation is configurable to target different physiological functions with surgical implantation of the neurostimulator at a singular location. Such systems and methods include (i) anatomical specificity to target the appropriate region of the spinal cord for stimulation, (ii) electrical specificity to provide the appropriate stimulation by delivery method, frequency, pulse duration, and other factors, and (iii) physiological specificity to evoke, suppress, increase, or decrease a specific physiological result.

  • Patent number: 11813446
    Abstract: The present invention relates to methods for improvement in lower urinary tract function in an individual with neurogenic urological dysfunction through epidural stimulation of the spinal cord. In certain embodiments, the methods comprise applying a pattern of epidural electrical stimulation to the spinal cord of an individual with impaired lower urinary tract under stimulation parameters sufficient to improve the storage of fluid in the bladder, sensations of fullness and/or emptying, detrusor over-activity, high detrusor pressure, voiding the bladder, transitioning from a storage state to a voiding state, and decreasing detrusor-external urethral sphincter dyssynergia. In certain embodiments, additional patterns of epidural electrical stimulation may be applied simultaneously, such as to maintain a normotensive cardiovascular state of the individual.

  • Patent number: 11759677
    Abstract: A respiratory training device providing both inspiratory and expiratory functional evaluation and training, as well as independent regulation of both the inspiratory and expiratory airway resistance levels used during training. The respiratory training device also includes data acquisition, recording, storage, retrieval and display functions for airway pressure monitoring data to provide functional evaluation, physiological monitoring, and diagnostic features. The respiratory training device allows the user to easily develop and follow precise and advanced training protocols, and utilize the respiratory device in both the clinical and home setting.

  • Patent number: 11691016
    Abstract: Patients with spinal cord injuries have benefited from neurostimulation therapy comprising delivery of electrical stimulation to enable or excite neurological responses using an implantable neurostimulator having an electrode array. Dangerous levels of charge are avoided while providing multiple, simultaneous stimulation waveforms by inducing a short in an electrode when a monitored value reaches or exceeds a predetermined threshold.
