  • Publication number: 20170021087
    Abstract: A medical blood access system used for hemodialysis treatment to enable blood withdrawal for processing of blood by an external apparatus and return the same blood to a patient, comprising an interfacial fluid conduit between the machine and patient's blood supply which is repeatedly connectable along a guided pathway passing through epidermis and subcutaneous tissue via a naturally formed tissue tract to enter blood space, providing improved patient safely, convenience, effective prophylaxis, without bleeding or tissue trauma or pain, and is executable by the patient to precisely connect and disconnect with minimal disfigurement or life restrictions, and is useable on virtually all patients soon after placement and is robust and safe to high blood flow.

  • Patent number: 9440018
    Abstract: A method for filtering blood including: withdrawing blood from an adult patient; performing ultrafiltration by filtering the withdrawn blood in a filter having an active filter membrane surface of no greater than 0.2 meters squared (m2) to remove ultrafiltrate from the blood, wherein the filter membrane blocks the passage of blood molecules having a molecular weight of at least 60,000 Daltons, wherein an amount of the removed ultrafiltrate is an effective therapeutic amount for treating a fluid overload condition of the patient; infusing the ultrafiltrated blood into the adult patient, and pumping the ultrafiltrate from the filter a rate no greater than one liter per hour.

  • Publication number: 20130190724
    Abstract: Catheters used for medical treatment, e.g., hemodialysis are filled with a locking solution, usually heparin between treatments. To prevent infections, antimicrobial or antibiotic substances have been used as locking solution alone or in combination with antithrombotic substances. It has been found that these locking solutions are rapidly washed out from the catheter tip. The invention describes a thixotropic gel that can be used as locking solution. Beneficial substances, e.g., antimicrobial or antibiotic substances can be added to the gel. A preferred antimicrobial substance is taurolidin alone or in combination with salicylic acid or one of its salts.

  • Patent number: 7311689
    Abstract: A method and apparatus for ultrafiltration of blood operating by removing blood from a peripheral blood vessel at a rate of less than two percent of total cardiac output of a patient, extracting fluid at a rate of 0.1 liter to 1.0 liters per hour while retaining cells and proteins in the blood, and returning the concentrated blood to a secondary blood vessel is disclosed. Blood is removed and returned using small gage needles. As a pump circulates blood from the patient, a filter removes ultrafiltrate from the blood using duty cycle or pump control, and a transparent container collects the removed fluid.

  • Patent number: RE38869
    Abstract: An extracorporeal blood circuit is disclosed for withdrawing, filtering and returning blood from peripheral blood vessels. The blood passage in the circuit extends through a withdrawal tube connected to a catheter in a peripheral vein, a filter, one or more pressure sensors and return tube also connected to a catheter in a peripheral vein (which may or may not be the same vein as used for the withdrawal tube). The blood passage is air free, and has smooth passage walls which promoted continuous and uniform flow of the blood through the circuit.
