Patent number: 9002159Abstract: An optical switch (10) includes a light input (12a), a plurality of light outputs (12b) and at least one light pathway movable from a first position where a light communication path is formed between a light input (14a) and a first light output (14b) and a second position where a light communication path is formed between the light input and a plurality of light outputs. Multiple light pathways are configured within the switch and selectable by rotation of a switch housing part enabling sequential selection of light communication paths. The switch can be used on a surgical device to control illumination of the surgical field during a procedure.Type: GrantFiled: August 30, 2011Date of Patent: April 7, 2015Assignee: CardioPrecision LtdInventors: Ying Sutherland, Fraser William Havern Sutherland, John Targell

Patent number: 8517975Abstract: A device and a method for generating therapeutic foam from a sclerosing solution such as polidocanol and a gas which is absorbable or dissolvable in the body comprises a disposable cassette including a liquid container and a flexible chamber containing gas, chamber being formed as a loop. Located in the loop chamber is a foam generating mesh. In use, liquid is introduced into the chamber and then the cassette is inserted into a pumping machine where it is engaged by a peristaltic pump which circulates the contents of the loop chamber through the mesh, thus creating foam. When a steady state is reached, foam may be withdrawn using a syringe via either a port or septum.Type: GrantFiled: July 9, 2012Date of Patent: August 27, 2013Assignee: BTG International Ltd.Inventors: David Dakin Iorwerth Wright, Anthony David Harman, Garry Hodges, David John Targell, Mark Simpson Yeoman, Jeremy Francis Donnan
