    Abstract: The disclosure relates to devices and methods for the treatment of edema, which devices use a restrictor for flow compensation. Devices and methods of the invention further use a flow-restrictor in the circulatory system, upstream of an intravascular pump, to balance pressure changes induced by the pump and to compensate for downstream flow. The device may be provided as an indwelling, intravascular catheter with a mechanical pump such as an impeller and a selectively deployable restrictor such as an inflatable balloon. Congestive heart failure or edema is treated by\operating the pump in an innominate vein and using the restrictor for flow compensation, to restrict the upstream flow and thus amplify or maintain pressure reduction at the lymphatic outlet.

  • Patent number: 10575985
    Abstract: The invention relates to a method and apparatus for controlling the inner temperature of a patient, comprising the steps of creating a fluid circuit that comprises a patient and a heat exchanger, the power supply thereto being controlled by a controller; subjecting at least a portion of the fluid in said circuit to the heat exchanger; directing the subjected fluid to and into the patient to control the temperature of the patient; estimating the organ temperature of the patient by a model that has been obtained on a mammal other than the patient; and controlling the power supply to the heat exchanger such that the estimated organ temperature does not exceed a threshold organ temperature, potentially taking into account estimated future organ temperatures. The invention further relates to a method and apparatus for controlling the inner temperature of a patient when subject to whole body hyperthermia, and to a method for obtaining the model.

  • Patent number: 10159601
    Abstract: A method and delivery system are disclosed for creating an aqueous flow pathway in the trabecular meshwork, juxtacanalicular trabecular meshwork and Schlemm's canal of an eye for reducing elevated intraocular pressure. Pulsed laser radiation is delivered from the distal end of a fiber-optic probe sufficient to cause photoablation of selected portions of the trabecular meshwork, the juxtacanalicular trabecular meshwork and an inner wall of Schlemm's canal in the target site. The fiber-optic probe may be advanced so as to create an aperture in the inner wall of Schlemm's canal in which fluid from the anterior chamber of the eye flows. The method and delivery system may further be used on any tissue types in the body.
