  • Patent number: 10967167
    Abstract: Certain substances (e.g., large molecules) that ordinarily cannot traverse the blood brain barrier can be introduced into the brain by applying an alternating electric field to the brain for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the blood brain barrier. In some embodiments, the frequency of the alternating electric field is less than 190 kHz (e.g., 100 kHz). Once the permeability of the blood brain barrier has been increased, the substance is able to cross the blood brain barrier.

If the device experiences relaxation, resulting in a decreased radial force against the vessel wall, the elastomeric tensioners may provide a contraction force to the inner layer and the outer layer, resulting in a maintained radial force on the vessel wall.

  • Patent number: 10028376
    Abstract: Some aspects of this disclosure generally are related to improving the robustness of a flexible circuit structure, for example, by providing fault-tolerant electrical pathways for flow of electric current through the flexible circuit structure. In some embodiments, such fault tolerance is enhanced by way of a conductive mesh provided between an adjacent pair of resistive elements. Some aspects are related to improved voltage, current, or voltage and current measurement associated with various pairs of adjacent resistive elements at least when the various pairs have differing distances between them.

  • Patent number: 9962541
    Abstract: A stimulation lead includes an electrode carrier disposed along a distal portion of a lead body. The electrode carrier defines multiple segmented-electrode-receiving apertures extending between an outer surface and a central lumen. Each of the segmented-electrode-receiving apertures includes a ledge disposed around a perimeter of that segmented-electrode-receiving aperture and inset from the outer surface of the electrode carrier. The stimulation lead also includes multiple segmented electrodes, with each of the segmented electrode disposed in a different one of the segmented-electrode-receiving apertures with an outer stimulation surface exposed through the segmented-electrode-receiving aperture and an inner surface abutting the ledge disposed around the perimeter of that segmented-electrode-receiving aperture. Conductive wires extend along the lead body and couple the segmented electrodes to terminals.

  • Patent number: 9950164
    Abstract: Methods and devices to treat discogenic lumbar back pain are disclosed. Electrodes are implanted within the anterior epidural space of the patient. A pulse generator that is connected to the electrodes delivers electrical impulses to sympathetic nerves located within the posterior longitudinal ligament (PLL) of the lumbar spine and outer posterior annulus fibrosus of the intervertebral disc. In alternate embodiments, energy directed to nerves in the PLL may be from light or mechanical vibrations, or the nerves may be cooled. The electrodes may also be used diagnostically to correlate spontaneous nerve activity with spinal movement, fluctuations in autonomic tone and the patient's experience of pain. The electrodes may also be used to generate diagnostic evoked potentials. The diagnostic data are used to devise parameters for the therapeutic nerve stimulation. Automatic analysis of the data may be incorporated into a closed-loop system that performs the nerve stimulation automatically.

  • Patent number: 9901714
    Abstract: A stylet for use in guiding a distal tip of a catheter to a predetermined location within the body of a patient. In one embodiment the stylet is configured for use within a lumen of the catheter and comprises a core wire, an ECG sensor, and a magnetic assembly. The ECG sensor senses an ECG signal of a patient when the stylet is disposed within the lumen of the catheter and the catheter is disposed within the body of the patient. The magnetic assembly includes at least one element capable of producing a magnetic or electromagnetic field for detection by a sensor external to the patient. In another embodiment, the stylet includes a pre-shaped distal segment that is deflected with respect to a more proximal portion of the stylet, which in turn causes a distal segment of the catheter to be deflected when the stylet is received within the lumen.

  • Patent number: 9802051
    Abstract: Systems and methods for providing a trial neurostimulation to a patient for assessing suitability of a permanently implanted neurostimulation are provided herein. In one aspect, a trial neurostimulation system includes an EPG patch adhered to a skin surface of a patient and connected to a lead extending through a percutaneous incision to a target tissue location. The EPG may be a modified version of the IPG used in the permanent system, the EPG may be smaller and/or lighter than the corresponding IPG device. The EPG and a lead extension may be sealed to allow improved patient mobility and reduced risk of infection. The EPG may be compatible with wireless systems used to control and monitor the IPG such that operation and control of the EPG is substantially the same in each system to allow seemless conversion to the permanently implanted system.

  • Patent number: 9802037
    Abstract: An electrical stimulation device comprises a stimulation lead with a tension section to prevent induction of an electrical current when the electrical stimulation device is in the presence of a magnetic field generated by a device such as an MRI machine. The tension section is shaped to organize excess length of the stimulation lead while providing a variable length between a distal end of the stimulation lead and an electrical source. The shape of the tension section avoids coils and may utilize combinations of straight and curved legs that lie substantially in a common plane to both organize excess length of the stimulation lead and prevent electrical induction.
