  • Patent number: 11253314
    Abstract: The disclosure describes devices, systems, and techniques for identifying and treating bladder dysfunction. In one example, a method includes identifying one or more focal points at respective locations of bladder tissue of a bladder of a patient, the one or more focal points initiating coordinated contractions of a detrusor muscle. The method may also, or alternatively, include ablating, for each of the one or more focal points, a respective portion of the bladder tissue at the respective location of the focal point. Ablation of these targeted portions of the bladder tissue may reduce the coordinated contractions of the detrusor muscle and alleviate overactive bladder symptoms.

  • Publication number: 20220049673
    Abstract: A valve assembly for a pump includes an electrical actuator having a stator and an armature. The stator includes an annular outer stator portion and an annular inner stator portion, and an annular channel formed radially between the outer stator portion and the inner stator portion. A first radial channel extending through the annular outer stator portion between an outer surface of the outer stator portion and the annular channel, and at least one second opening in the annular outer stator portion results in magnetic symmetry of the stator . Upon activating the electrical actuator, the attraction of the armature towards the stator is uniform thus displacing fluid between the stator and armature in a uniform manner and to avoid high velocity, potentially damaging fluid flow.

  • Patent number: 11202908
    Abstract: In some examples, electrical stimulation is delivered to a patient such that selective termination of the stimulation causes a therapeutic effect in the patient after termination of the electrical stimulation to the patient. The electrical stimulation may be insufficient to produce a desired therapeutic effect in the patient during stimulation, but sufficient to induce a post-stimulation desired therapeutic effect following termination of the stimulation. In some examples, the electrical stimulation may be sub-threshold electrical stimulation. In some examples, the desired therapeutic effect may alleviate bladder dysfunction, bowel dysfunction, or other disorders. The stimulation may be selectively terminated in response to one or more therapy trigger events to induce the post-stimulation therapeutic effect.

  • Publication number: 20210369169
    Abstract: In some examples, a processor determines a patient state based on activity of a bioelectrical brain signal of a patient in one or more frequency sub-bands of a frequency band of interest. For example, a processor may determine a patient state based on the power level of a bioelectrical brain signal of the patient in one or more frequency sub-bands of a frequency band, or based on a spectral pattern of a bioelectrical brain signal in a frequency band, such as a shift in a power distribution between sub-bands, a change in the peak frequency within one or more sub-bands, a pattern of the power distribution over one or more frequency sub-bands, or a width or a variability of one or more sub-bands exhibiting a relatively high or low level of activity.

  • Publication number: 20210340831
    Abstract: Systems and methods for landing a tubing hanger in a wellhead, landing a tree on the wellhead, and making electrical and hydraulic couplings between the tree and the tubing hanger without having to orient the tree or the tubing hanger relative to each other are provided. This is accomplished using a seal sub that is coupled to the tree and lowered with the tree into contact with the tubing hanger located in the wellhead. The seal sub features an electrical conductor that facilitates electrical coupling of the tree to the tubing hanger. The tubing hanger and seal sub may include a metal-to-metal and elastomeric seal arrangement designed to seal off electrical and hydraulic connections between these components when, the tree is positioned within the wellhead.

  • Patent number: 11116980
    Abstract: Techniques for delivering electrical stimulation therapy comprising a complex variation to at least one electrical stimulation parameter are described. In one example, processing circuitry of an implantable medical device (IMD) identifies a plurality of electrical stimulation parameters for at least one pulse train of electrical stimulation. The processing circuitry defines a complex variation to at least one electrical stimulation parameter of the plurality of electrical stimulation parameters. The processing circuitry modifies the at least one pulse train of electrical stimulation by introducing the complex variation to the electrical stimulation parameter function and controls a stimulation generator of the IMD to generate, as modified, the at least one pulse train of electrical stimulation.

  • Patent number: 11112052
    Abstract: Systems repair jet pump elbow joining structures like RS1 and RS2 welds. Systems include a base having legs that secure to ends of the elbow in different directions, and a drive plate that joins to flow conduits where they meet the elbow. The drive plate and base may then be pushed together, resulting in compression or joining of the elbow and flow conduit. Multiple drive plates may be used with a single base to compress multiple flow conduits to the base. The base and the drive plates can be driven together with a driving bolt extending through the base and driving plate. To provide a better fit, grooves can be created in the flow conduits through machining from the installed base. The drive plate may be seated into the groove to achieve a desired orientation with less slippage. Example embodiments and methods do not require welding or a welding base.

  • Patent number: 11100713
    Abstract: Techniques for aligning a virtual object with a physical object in an Augmented Reality (AR) or Virtual Reality (VR) application are described. An electronic peripheral includes a first inertial measurement unit (“IMU”). A head mounted display includes a second IMU. An estimated attitude for the electronic peripheral is generated using data from the first IMU. An estimated attitude for the head mounted display is generated using data from the second IMU. An orientation of a virtual object is determined based on the estimated first and second attitudes, such that the virtual object is aligned with an object in a user's physical environment when the virtual object is displayed to the user. The virtual object is displayed on the head mounted display.
