  • Patent number: 9005102
    Abstract: Energy emitting systems are provided which include an adjustable conductive coil configured to generate a magnetic or electromagnetic field focused on a target nerve. The coil includes a central aperture which may be adjustable between a first configuration and a second configuration having a radius greater than the radius of the first configuration. The adjustable or movable nature of the coil allows the conductive coil to conform to, accommodate, or be positioned on a particular anatomical structure of a patient to position the coil in proximity to the underlying target nerve. In certain embodiments, methods of magnetic induction therapy are provided which include positioning a conductive coil relative to a portion of a patient's body by adjusting the central aperture of the coil such that the coil may conform to, accommodate or be positioned on the portion of the patient's body in proximity to the underlying target nerve.

  • Patent number: 8992409
    Abstract: There is provided a method for controlling a flow of fluid and/or other bodily matter in a lumen formed by a tissue wall of a patient's organ. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow in the lumen, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the lumen. The method can be used for restricting or stopping the flow in the lumen, or for actively moving the fluid in the lumen, with a low risk of injuring the organ. Such an organ may be the esophagus, stomach, intestines, urine bladder, urethra, ureter, renal pelvis, aorta, corpus cavernosum, exit veins of erectile tissue, uterine tube, vas deferens or bile duct, or a blood vessel.

  • Patent number: 8934976
    Abstract: Feedback systems and methods enhance obstructive and other obesity treatments by presenting feedback regarding patients' actual eating. An ingestion restricting implant body can be deployed along the gastrointestinal tract. In some embodiments, ingestion alters the implant body, which, in turn, generates signals. The generated signals can be used to inhibit unhealthy ingestion by the patient. In other embodiments, the implant body can be altered by signals so as to selectable change the restriction imposed on the gastrointestinal tract, optionally in response to ingestion events, an eating schedule, or the like. The implant body may comprise a gastric band. Sensor signals may be processed to identify ingestion and/or characterize ingestion material, and the results may be displayed on a screen for a patient or coach to view.

  • Publication number: 20140378941
    Abstract: Techniques, devices, and systems may include screening effective therapies using cortical evoked potentials. In one example, a system may be configured to receive a first sensed cortical evoked potential of a patient that occurred in response to an induced sensation at an anatomical region different from a brain region of the patient and receive a second sensed cortical evoked potential that occurred in response to electrical stimulation delivered to one or more nerves associated with the anatomical region. The electrical stimulation may be at least partially defined by a set of therapy parameter values. The system may also compare a first value of a characteristic of the first sensed cortical evoked potential to a second value of the characteristic of the second sensed cortical evoked potential and determine, based on the comparison, efficacy of a therapy configured to treat a condition associated with the anatomical region.

  • Patent number: 8918175
    Abstract: Electrical stimulation therapy may be delivered to a patient to selectively and independently address different conditions of a pelvic floor disorder of the patient. The conditions of a pelvic floor disorder may include, for example, a lower urinary tract dysfunction (e.g., urinary or fecal incontinence) and sexual dysfunction (e.g., an impaired sexual reflex response to a sexual stimulus). In some examples, a system is configured to selectively deliver a first electrical stimulation therapy that is configured to elicit an inhibitory physiological response from the patient related to voiding, a second electrical stimulation therapy that is configured to improve a sexual reflex response of the patient to a sexual stimulus, and a third electrical stimulation therapy that is configured to both elicit the inhibitory physiological response from the patient related to voiding and increase a sexual response of the patient to a sexual stimulus.

  • Publication number: 20140364678
    Abstract: A neuro-stimulation system employs a includes a stimulator which may include electrode devices and/or vibration elements. A controller may be employed to drive the stimulating elements with an electrical signal. In response to the electrical signal, the stimulating elements deliver electrical and/or mechanical stimulation to the body part. The stimulation may be an aperiodic stimulation and/or may be a subthreshold stimulation. In one embodiment, the stimulator is disposable and the processor determines usage of the stimulator and ensures that the stimulator is limited to a certain amount of use. Neuro-stimulation systems may be applied to sensory cells of body parts during movement of the body parts to induce neuroplastic changes. Such movement may involve a variety of therapeutic applications, e.g. in stroke patient therapy.
