  • Publication number: 20140178532
    Abstract: The present invention relates to a beverage mixing apparatus. Specifically, the present invention relates to a filter containing coffee, tea, or another additive to be mixed with a liquid. The filter is formed into a ball and attached to a rigid stick for stirring and mixing the contents of the present invention into a liquid. The filter may keep solid beverage additives separate from the liquid while still allowing the two to mix. Soluble additives may pass freely through the filter.

  • Patent number: 8606347
    Abstract: In one embodiment, a catheter locator apparatus is configured to determine the location of the tip of a catheter as it is inserted used in a human body. In one example embodiment, where a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and hence its depth in the body of a patient.

  • Patent number: 8265732
    Abstract: This invention relates to a method of catheter and radiating coil location in a human body and in particular to the determination over time of the location of the tip of a catheter as it is inserted and during its use in the body. In particular when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and hence its depth in the body of a patient. To assist a clinician using the coil-locating device, a display is provided that shows both a reference image of a part or portion of a body (non-subject body) and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on or over a predetermined landmark on the patient's body. The coil and its associated signal wires can be incorporated into a stylet, guide wire or a catheter.

  • Publication number: 20080065171
    Abstract: A method of treating shoulder dysfunction involves the use of a percutaneous, intramuscular stimulation system. A plurality of intramuscular stimulation electrodes are implanted directly into select shoulder muscles of a patient who has suffered a disruption of the central nervous system such as a stroke, traumatic brain injury, spinal cord injury or cerebral palsy. An external microprocessor based multi-channel stimulation pulse train generator is used for generating select electrical stimulation pulse train signals. A plurality of insulated electrode leads percutaneously, electrically interconnect the plurality of intramuscular stimulation electrodes to the external stimulation pulse train generator, respectively. Stimulation pulse train parameters for each of the stimulation pulse train output channels are selected independently of the other channels. The shoulder is evaluated for subluxation in more than one dimension.
