  • Patent number: 10561839
    Abstract: A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinsonian tremor, and other forms of tremor. The stimulator can have electrodes that are placed circumferentially around the patient's wrist or arm. Specific nerves in the wrist or arm can be targeted by appropriate spacing of the electrodes. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. The stimulation pattern may alternate between the nerves. Improved stimulation algorithms can incorporate tremor feedback, external data, predictive adaptation, and long-term monitoring data.

  • Publication number: 20200029948
    Abstract: Systems and methods for minimally invasive treatment of target tissue among one or more passageways include a flexible elongate device, a tool including a first tubular member, and an instrument to perform treatment on target tissue around the target location. The flexible elongate device includes a proximal end, a distal end, and a lumen therebetween. The tool is configured for deployment within the lumen to a passageway exit site, puncturing a passageway wall at the passageway exit site, and deployment to a target location. The instrument is sized to be deployed within the tool. In some embodiments, the systems and methods further include an anchor configured to stabilize the tool. In some embodiments, the first tubular member is a first hollow sheath configured to be deployed past the distal end of the flexible elongate device to the passageway exit site.

  • Publication number: 20200030575
    Abstract: The following describes various applications and uses for a controllably rigidizable flexible device or sheath. Such rigidizing mechanisms can allow for a transition between a rigid state and a flexible state of a sheath. Rigidization can be applied along an entire length of a flexible sheath or along select portions of the sheath, and the rigidization can be of varying stiffness. Rigidization can be user controlled or automatically controlled using computer processes.

  • Patent number: 10492741
    Abstract: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.

  • Publication number: 20190298451
    Abstract: The systems and methods of the present disclosure are for use in a surgical procedure in which an elongate flexible medical device is utilized to create a model of patient anatomy using information from one or more of a localization sensor and an imaging sensor. Anatomical areas of interest may be identified and displayed on the model of patient anatomy, which may be used in performing a medical procedure on at least one of those areas of interest.

  • Publication number: 20190134393
    Abstract: Disclosed herein are systems, devices, and methods for peripheral nerve stimulation, particularly for treating tremor. The nerve stimulation may be accomplished by a wearable nerve stimulation device, such as a band configured to be worn on the wrist or other body part. The device can accomplish targeted nerve stimulation using circumferentially spaced electrodes. In some embodiments, the device may use only the same number of electrodes as the number of nerves that are to be stimulated. A biphasic charge-balanced waveform may be used to selectively stimulate a nerve near one of the activated electrodes but not to stimulate the nerve near the other activated electrode. The device may use dry electrodes for long-term, repeated use. The dry electrodes may include a conductive base layer and a polymeric, plastic or rubber skin contact layer comprising a conductive filler. The filler may be a powder, fiber, conductive coating, etc.
