Patent number: 11292640Abstract: A device is described for facilitating the preparation of therapeutic foam e.g. for the treatment of varicose veins. A pressurised vial contains a sclerosant liquid, e.g., polidocanol solution, and a sterile gas which is readily absorbed by the body, e.g., carbon dioxide, oxygen or a mixture of these gases. The vial is provided either with a specialised stopper/seal into which a syringe nozzle may be inserted or alternatively a septum seal which may be penetrated by a hypodermic needle. The quantities of gas and liquid and the pressure in the vial are pre-set so that, on connection of a syringe to the vial, a predetermined volume of both gas and liquid is transferred to the syringe, with the intention that the syringe is then used to make a foam by known means. The use of the vial ensures that the ratio of gas to liquid in the foam is standardised, and also provides a convenient way of packaging the gas and liquid and of filling the syringe in a sterile manner.Type: GrantFiled: September 15, 2020Date of Patent: April 5, 2022Inventors: Anthony David Harman, Jan Willem Marinus Mijers, Nikki Robinson

Patent number: 10773864Abstract: Vessel having sterile contents containing in predetermined proportions (i) a foamable liquid and (ii) a gas or gas mixture other than air. The contents are at a pressure above atmospheric pressure. The vessel has an outlet which is adapted to cooperate with a syringe nozzle and which has associated with it a breakable seal or a valve.Type: GrantFiled: August 27, 2014Date of Patent: September 15, 2020Assignee: EKOS CORPORATIONInventors: Anthony David Harman, Jan Willem Marinus Mijers, Nikki Robinson

Patent number: 10472100Abstract: A therapeutic foam for the treatment of, inter alia, varicose veins comprises a sclerosing solution foamed with a physiological gas such as carbon dioxide, oxygen or a mixture thereof. The foam has a nitrogen content of less than 0.8%. It may be generated using a pressurized canister system incorporating a fine mesh of micron dimensions through which the gas and sclerosing liquid are passed to make the foam. Alternatively, the foam may be generated by passing gas and solution between two syringes through a fine mesh. Techniques are described for minimizing the amount of nitrogen in a canister or syringe based product. A technique for generating and delivering foam simultaneously using a syringe based device is also disclosed.Type: GrantFiled: May 8, 2015Date of Patent: November 12, 2019Assignee: BTG International Ltd.Inventors: David Dakin Iorwerth Wright, Anthony David Harman, Nikki Robinson, Garry Hodges, Adil Kadar, Geoffrey D.
