Minimally invasive implantable neurostimulation system

A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site. The implantable medical device includes a housing, an electronic circuit within the housing, and an electrical lead comprising a lead body extending between a proximal end coupled to the housing and a distal end extending away from the housing and at least one electrode carried by the lead body. The delivery tool includes a first cavity for receiving the housing and a second cavity for receiving the lead. The first cavity and the second cavity are in direct communication for receiving and deploying the housing and the lead coupled to the housing concomitantly as a single unit.

System and method for modeling brain dynamics in normal and diseased states

A system and method is provided for modeling brain dynamics in normal and diseased states.

Nerve stimulation device for unidirectional stimulation and current steering

A nerve interface device including at least one cuff portion having an assembled position in which the cuff portion forms at least part of a passageway for receiving a nerve along a longitudinal axis passing through the passageway; and first and second rings of electrodes mounted on the at least one cuff portion, each ring of electrodes including a plurality of electrodes. Each electrode in the first ring has a corresponding longitudinally-aligned electrode in the second ring so as to form a plurality of pairs of electrodes spaced apart from each other along the longitudinal axis. The plurality of pairs of electrodes includes at least a first pair of electrodes, the first pair of electrodes mounted on the at least one cuff portion. The at least one cuff portion includes an asymmetric configuration about a central axis perpendicular to the longitudinal cuff axis.

METHODS AND SYSTEMS FOR STIMULATING NERVE SIGNALS

Systems and methods of generating and applying a synthetic neuromodulatory signal are described. A subject may be put under a particular condition that causes an effect in the subject. While the subject is under the condition, a recording of neurogram signals derived from the condition can be made from the subject. For example, neuronal signals traveling on the vagus nerve of the subject may be monitored and recorded. The neurogram may then be used to create a synthetic neuromodulatory signal that can be administered to a user. When the synthetic neuromodulatory signal is administered to the user, the user may experience the same effect as the subject that had been placed in the condition, even though the user was never put under the same condition.

Methods, systems, and apparatus for closed-loop neuromodulation

Systems, apparatus, and methods for treating medication refractory epilepsy are disclosed. In one embodiment, a method of treating epilepsy is disclosed comprising detecting, using a first electrode array coupled to a first endovascular carrier, an electrophysiological signal of a subject. The method further comprises analyzing the electrophysiological signal using a neuromodulation unit electrically coupled to the first electrode array and stimulating an intracorporeal target of the subject using a second electrode array coupled to a second endovascular carrier implanted within a part of a bodily vessel superior to a base of the skull of the subject.

Renal neuromodulation methods and devices for treatment of polycystic kidney disease

Methods for treating polycystic kidney disease with therapeutic renal neuromodulation and associated systems and methods are disclosed herein. One aspect of the present technology is directed to methods that at least partially inhibit sympathetic neural activity in nerves proximate a renal artery of a kidney of a patient. One or more measurable physiological parameter corresponding to the polycystic kidney disease can thereby be reduced. Moreover, central sympathetic drive in the patient can be reduced in a manner that treats the patient for the polycystic kidney disease. Renal sympathetic nerve activity can be modulated along the afferent and/or efferent pathway. The modulation can be achieved, for example, using an intravascularly positioned catheter carrying a neuromodulation assembly, e.g., a neuromodulation assembly configured to cryotherapeutically cool the renal nerve or to deliver an energy field to the renal nerve.

BATTERYLESS IMPLANTABLE MICROSTIMULATORS

Methods and apparatuses (e.g., devices and systems) for vagus nerve stimulation, including (but not limited to) sub-diaphragmatic vagus nerve stimulation. In particular, the methods and apparatuses described herein may be used to stimulate the posterior sub-diaphragmatic vagus nerve to treat inflammation and/or inflammatory disorders. The implantable microstimulators described herein may be leadless and batteryless.

A neural stimulator, suitable for implanting in a recipient, and configured to combine vagal nerve stimulation (VNS) with cochlear stimulation, to result in faster adaptation to new sounds and maps, and alleviation of tinnitus in the recipient.

STEREOGNOSIS TRAINING SYSTEM AND METHOD FOR PATIENTS WITH CHRONIC STROKE, SPINAL CORD INJURY OR NEUROPATHY

Provided is an effective stereognosis training system that integrates hardware and software to provide a simple, reliable, quantitative system to provide tactile rehabilitation and progress monitoring. The system can include an interactive device including a novel set of objects, that are combined with neuromodulatory systems such as wireless closed-loop vagus nerve stimulation to improve neural plasticity and expedite functional recovery. The system can send updates to therapists or clinicians to monitor progress and encourage compliance with prescribed therapy.

Methods and apparatuses for reducing bleeding via coordinated trigeminal and vagal nerve stimulation

Disclosed are apparatuses and methods for reducing or limiting blood loss and reducing bleed time in a subject by combined vagus and trigeminal stimulation. The apparatuses and methods may activate (e.g., electrically) one or more branches of the trigeminal nerve and may concurrently (at overlapping or near-overlapping time) independently activate the vagus nerve. This activation may be invasive or non-invasive.
