  • Publication number: 20240206959
    Abstract: A microcatheter is provided with a vascular spasm-inducing probe at its distal end. The spasm-inducing probe can include an electrical current, radiofrequency energy, ultrasound, chemical, or thermal modulator. When the spasm-inducing probe is activated in a vessel, the vessel narrows about the element. This permits a therapeutic agent to be delivered through the infusion lumen and out of the orifice under high pressure, while the narrowing of the vessel operates as a pseudo-valve and prevents reflux of the therapeutic agent past the narrowing of the vessel.

  • Publication number: 20230292992
    Abstract: A capsule device with thermally-stable specific gravity control is disclosed. The capsule device comprises a capsule unit adapted to be swallowable by a human subject and an inflatable balloon comprising a thermally-stable effervescent formulation inside the inflatable balloon, where the thermally-stable effervescent formulation has a particular particle size between a first mesh size and a second mesh size, and the inflatable balloon is attached to the capsule unit. After the capsule unit with the inflatable balloon attached is swallowed, the inflatable balloon starts to inflate so as to lower specific gravity of a combination of the capsule unit and the inflatable balloon when the inflatable balloon is exposed to body fluid and the body fluid gets in touch with the thermally-stable effervescent formulation inside the inflatable balloon.

  • Patent number: 11116390
    Abstract: The present invention discloses a capsule endoscope with specific gravity control. The capsule endoscope comprises a housing to enclose various components, an inflatable device attached to a first longitudinal end of the capsule unit and an enteric coated shell attached to the first longitudinal end of the capsule unit to enclose the inflatable device between the enteric coated shell and the capsule unit. The various components include a camera sub-system for capturing image frames. The inflatable device comprises an inflatable membrane and an effervescent formulation inside the inflatable membrane. The enteric coated shell fits tightly onto the first longitudinal end of the capsule unit to prevent body liquid from leaking into a space between the enteric coated shell and the capsule unit when the capsule unit travels in human gastrointestinal tract after being swallowed.
