Publication number: 20190159786Abstract: The present invention relates to methods and devices for production of injectable foams, such as those used in the treatment of varicose veins and other venous disorders. The method requires the delivery or supply of foamable liquid sclerosing agent and a suitable gas or a gas mixture to a foam producing structure in which the liquid and gas are combined to produce foam, wherein the liquid is delivered independently of the delivery of gas. Devices for producing injectable foam comprise a foam producing structure in which liquid and gas are combined to produce foam, the structure comprising an inlet for liquid and gas and an outlet for foam; a liquid pathway in communication with the inlet; and a gas pathway in communication with the inlet, characterised in that the liquid pathway comprises a means for delivering liquid through the liquid pathway independently of gas delivery through the gas pathway. In preferred embodiments, the delivery of liquid and/or gas is controlled with volumetric pumps.Type: ApplicationFiled: July 26, 2017Publication date: May 30, 2019Inventors: Carol Suzanne BALFOUR, David Ian FAULKNER, Stafford MOSS, Thomas WYSS, Rex FAITHFULL, Thomas AJAO

Publication number: 20190159787Abstract: Illustrative methods of manufacturing flexible drive shaft assemblies for preparing bone can include steps such as providing, receiving or manufacturing a mold. Injecting a first polymeric material into the mold to form a coupling member, the coupling member adapted for attachment to a torque-providing driving tool. Injecting a second polymeric material into the mold to form a work member, the work member adapted to interface with the bone to prepare the bone. The method can further include injecting a third polymeric material into the mold in an overmolding process to form a flexible shaft extending from the coupling member to the work member. The assemblies resulting from such methods can include a flexible shaft that is adapted to transmit a majority of a torque received from a torque-providing driving tool through the flexible shaft. In some examples, the flexible shaft can include a solid polymeric shaft.Type: ApplicationFiled: November 28, 2018Publication date: May 30, 2019Inventor: Steven Conrad

Publication number: 20190159789Abstract: A cutting device for cutting a patient's sternum includes a laser source adapted to generate a cut laser beam, a beam adjusting structure arranged for directing the cut laser beam generated by the laser source along a predefined cut geometry at the sternum, a support that carries the laser source and, optionally, a correction arrangement. The support has a mounting structure adapted to be fixed to a patient's rib cage such that the laser source is in a predefined position with respect to the sternum. The correction arrangement is adapted to automatically identify a movement of the laser source relative to the sternum causing the cut laser beam to deviate from the predefined cut geometry. It is further adapted to automatically adjust the position of the laser source relative to the sternum to correct the deviation of the cut laser beam with respect to the predefined cut geometry.Type: ApplicationFiled: June 22, 2017Publication date: May 30, 2019Inventors: Alfredo E. BRUNO, Philippe C. CATTIN
