Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.Type: GrantFiled: April 3, 2008Date of Patent: October 15, 2013Assignee: Dfine, Inc.Inventors: Csaba Truckai, Robert Luzzi, John H.

Patent number: 8546462Abstract: A bone cement is provided that includes a solid component and a liquid component. The solid component and liquid component are mixed together to form the bone cement. After completion of the solid and liquid component mixing, the bone cement has an initial viscosity effective for manual application or manual injection onto or into a targeted anatomical location, e.g., bone, and the cement has stable viscosity range that over both time and temperature is effective for uniformly filling the targeted anatomical location, for example an osteoporotic bone or a fractured vertebral body, with minimal to no leakage of the cement from the targeted anatomical location. Additionally, both the initial viscosity and the stable viscosity of the bone cement are within a range that renders the bone cement effective for injection with a manually operated syringe or multiple syringes.Type: GrantFiled: June 30, 2011Date of Patent: October 1, 2013Assignee: DePuy Synthes Products, LLCInventors: Andreas Boger, Christoph Sattig, Stefan Deusser

Patent number: 8540723Abstract: A medical system and method can used to treat a bone. The system and method can include the preparation of bone cement to be used in the treatment. A non-liquid component and a liquid component can be combined to form a bone cement. A vacuum system can be used to saturate the non-liquid component with the liquid component. The bone cement and/or components can be heated and/or cooled.Type: GrantFiled: April 13, 2010Date of Patent: September 24, 2013Assignee: DFINE, Inc.Inventors: John H. Shadduck, Andrew Kohm

Publication number: 20130226188Abstract: 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: ApplicationFiled: April 12, 2013Publication date: August 29, 2013Applicant: ApaTech LTDInventor: ApaTech LTD

Publication number: 20130226142Abstract: Systems and methods for treating bone, such as vertebral compression fractures are disclosed. A method includes controllably applying energy to a bone cement volume outside of a patient's body to selectively accelerate the polymerization rate of the bone fill material volume prior to introduction into a bone. The method further includes sequentially introducing a plurality of cement carrying structures with the accelerated polymerization rate bone cement volume into the bone. A system for use in the method includes at least one elongated cement-carrying structure sized to carry a bone cement volume therein and an energy source operatively coupleable to the cement-carrying structure. The energy source applies energy to the bone cement volume to selectively accelerate a polymerization rate thereof. An elongated injector insertable into the bone has a passageway that removably receives the elongated cement-carrying structure to allow delivery of the accelerated polymerization rate bone cement into the bone.Type: ApplicationFiled: April 8, 2013Publication date: August 29, 2013Applicant: DFINE, Inc.Inventor: DFINE, Inc.

Publication number: 20130197530Abstract: A delivery system comprising a covering containing at least a first substance for release to a surgical site is provided. The covering includes an elongated containment portion having at least one compartment, wherein the covering retains the first substance for mixing with a second substance prior to delivery at a surgical site. The covering may be a single or multi compartment structure capable of retaining at least partially the mixture of the at least first and second substances until the covering is placed at the surgical site. The elongated containment portion of the covering includes a first end and second end opposite each other, wherein at least one end defines an access port configured to receive a device capable of delivering a second substance into the elongated containment portion for mixing with the first substance prior to or during the surgical procedure.Type: ApplicationFiled: January 26, 2012Publication date: August 1, 2013Applicant: Warsaw Orthopedic, Inc.Inventor: William F.
