  • Patent number: 10888640
    Abstract: Embodiments of the present invention provide a method of treating a stricture in a nonvascular body lumen such as urethral strictures, benign prostatic hyperplasia (BPH) strictures, ureteral strictures, esophageal strictures, sinus strictures, and biliary tract strictures. Embodiments of the present invention provide a method for treating at least one of benign prostatic hyperplasia (BPH), prostate cancer, asthma, and chronic obstructive pulmonary disease (COPD). The method can include delivering, for example, via drug coated balloon catheters, anti-inflammatory and anti-proliferative drugs (e.g., rapamycin, paclitaxel, and their analogues) and one or more additives.

  • Patent number: 10280904
    Abstract: An exemplary rotational assembly includes a base having a circular collar and first and second arms that rotate about the circular collar in opposite angular directions. In a stored state the arms have substantially the same angle relative to the circular collar; in a deployed state the arms have rotated into opposing positions. Each end of a Nitinol wire is coupled to the first and second arms and contracts when heated by the flow of electrical current. This contraction causes the simultaneously application of a rotational force to the first and second arms causing the first and second arms to rotate about the circular collar in opposite angular directions. The simultaneous counter rotating angular forces during rotation of the arms causes no substantial change in angular inertia at the base.

  • Publication number: 20090101047
    Abstract: A multimedia table that can be used by a hospital patient or home users. One side of the table can provide a tray in which the patient can use to eat. An opposite side of the table provides for an LCD device wherein a person can watch television. The patient can rotate the table so that the patient can utilize either side of the table as the patient desires. Thus, for example, the table can be useful for a patient lying in a hospital bed, recovering in a nursing home, at home, or any other user wherein the table can facilitate entertainment, communication, eating, etc.

  • Patent number: 6233748
    Abstract: An environmental protection system for rendering biological/chemical agents harmless has a source of radiation such as an ultraviolet light source, which is configured to irradiate a reactive surface, such as one formed of titanium dioxide. The reactive surface has an oxidation potential sufficient to cooperate with the source of radiation so as to render harmless biological/chemical agents in contact with the reactive surface.

  • Patent number: 6234172
    Abstract: A transportable life support system for providing medical care to a patient while transporting the patient from one location to another has a platform configured to receive the patient, a plurality of medical devices attached to the platform for providing medical monitoring and medical therapy to the patient, and a control and display panel comprising controls and displays for the medical devices. The control and display panel provides a centralized location for monitoring and controlling the medical devices so as to mitigate a need for an operator to move about the platform in order to individually observe a display for each medical device and to individually control each medical device.
