Patent number: 9375511Abstract: A bone graft material is provided comprising granules of synthetic bone material, at least some of which have a solid coating comprising a blood-clotting agent. A device for delivering bone-replacement material to a an area to be treated is also provided, the device comprising: a chamber for containing bone-replacement material, wherein the chamber is pre-loaded and/or pre-coated on an interior surface thereof with a blood-clotting agent; means for introducing bone-replacement material into the chamber to contact the blood-clotting agent; and a means for delivering the bone-substitute material from the chamber to the area to be treated.Type: GrantFiled: February 27, 2008Date of Patent: June 28, 2016Assignee: ApaTech LimitedInventors: Thomas Buckland, Charles Campion, James J. Cassidy

Patent number: 9179958Abstract: A delivery device for semi-solid implantable material such as synthetic bone graft substitutes. The device includes a handle, a cylinder extending from the handle and having an outlet at its distal end. A piston is operated by a trigger and is slidable within the cylinder to displace the material from the cylinder. The cylinder has a substantially constant inner diameter along its entire length such that the outlet has substantially the same inner diameter as the rest of the cylinder. When the trigger is fully depressed, a ratchet mechanism is disengaged allowing the piston to be pulled back to a starting position.Type: GrantFiled: April 12, 2013Date of Patent: November 10, 2015Assignee: ApaTech LTD.Inventors: Charles Campion, Thomas Buckland, Paul Kearsley

Patent number: 8439930Abstract: A delivery device for semi-solid implantable material such as synthetic bone graft substitutes. The device comprises a handle (1), a cylinder (2) extending from the handle and having an outlet at its distal end. A piston (23) is operated by a trigger (5) and is slidable within the cylinder to displace the material from the cylinder. The cylinder has a substantially constant inner diameter along its entire length such that the outlet has substantially the same inner diameter as the rest of the cylinder. When the trigger is fully depressed, a ratchet mechanism (14, 32) is disengaged allowing the piston to be pulled back to a starting position.Type: GrantFiled: February 26, 2009Date of Patent: May 14, 2013Assignee: Apatech Ltd.Inventors: Charles Campion, Thomas Buckland, Paul Kearsley
