20160095640 | CEMENT-DIRECTING ORTHOPEDIC IMPLANTS - A cement-directing structure for use in cement-injection bone therapy includes a collapsible, self-restoring braided structure with regions of differential permeability to the bone cement. The regions of differential permeability may be provided by areas where the braided mesh density is greater or lesser than surrounding areas and/or by means of a baffle. After the structure is placed in a void within a bony structure, cement is injected into the interior of the structure then oozes out in preferred directions according to the locations of the regions of differential permeability. | 04-07-2016 |
20160100875 | DEVICE TO PREPARE AND ADMINISTER TWO-COMPONENT MIXTURE - A device to prepare and administer a two-component mixture, including a first chamber in which a container is housed that is hermetically closed for a liquid component, a second chamber containing a powdered component, an opening of the container of the liquid component, a mixing member placed in the second chamber for preparing the mixture and a piston able to move in the second chamber to dispense the mixture. The mixing member includes a stem, passing through an opening for dispensing the mixture in the second chamber, having an outer end equipped with a handle and an inner end provided with a mixing blade connected to the inner end with a releasable connection. | 04-14-2016 |
20160106488 | BONE TREATMENT SYSTEMS AND METHODS - 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. | 04-21-2016 |
20160128750 | Apparatus for Delivery of Reinforcing Materials to Bone - An apparatus and methods for delivery of reinforcing materials to a weakened or fractured bone is disclosed. An apparatus for delivering a reinforcing mixture to a bone including a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass therethrough; a balloon engaging the tube wherein the balloon expands from a substantially deflated state to a substantially inflated state upon the bone reinforcing mixture entering the balloon; and at least one light guide extending through the tube into the balloon to guide a light into the balloon. | 05-12-2016 |
20160128751 | METHOD AND APPARATUS FOR DELIVERY OF BONE CEMENT - A method of applying bone cement for an orthopedic procedure of a patient includes coupling a proximal end of a nozzle component to a bone cement applicator and applying bone cement on a surface of an implant or on a bone surface through an elongated distal opening of a distal portion of the nozzle component. The method includes separating the distal portion from an intermediate portion of the nozzle component at a frangible connecting portion and exposing a circular distal end of the intermediate portion. | 05-12-2016 |
