Abstract
The disclosure provides device and related methods that can be used to treat edema by applying pressure to a blood vessel such as a jugular vein to restrict flow therein, creating a local decrease in blood pressure within the jugular vein near an outlet of a lymphatic duct, causing lymph to drain from the interstitium.
Claims21
A device for treating edema, the device comprising:
- an extended collar member dimensioned to extend at least partway around a neck of a patient;
- and
- a projection protruding inward from an inner surface of the collar member, the projection positioned to press against the neck near a jugular vein, thereby restricting blood flow within the jugular vein.
A method of draining lymph, the method comprising:
- restricting flow through a jugular vein of a patient by applying pressure to a neck of the patient at a spot on the neck proximal to the jugular vein, thereby decreasing pressure at an outflow of a lymphatic duct.
Dependencies are inferred from the claim text.
