20200405321 | CARDIAC IMPLANTABLE ELECTRONIC DEVICE POCKET COMPRESSION APPARATUS AND METHOD OF MITIGATING LOCALIZED BLEEDING USING SAME - A method mitigates pocket bleeding and hematoma formation in a patient by providing a pliable wrap having a solid block coupled with the wrap, and then securing the pliable wrap around the torso of the patient to align the solid block with the located localized torso area. The solid block at least in part covers the localized torso area. The wrap is secured to cause the wrap to apply a force, to the solid block, that produces a corresponding pressure on the localized torso area. The force applied to the solid block is high enough to cause the pressure to hinder blood flow to the localized torso area to promote clotting at the localized torso area. At the same time, the force applied to the solid block is low enough to cause the pressure to permit blood flow to the localized torso area to promote healing. | 2020-12-31 |
20200405322 | Limb sparing in mammals using patient-specific endoprostheses and cutting guides. - A method for performing surgery on a target bone with guidance from an adjacent bone adjacent to the target bone, the method using a cutting guide including a mounting portion, a cut guiding portion and a linking portion extending therebetween, the method comprising: mounting the mounting portion to the adjacent bone and positioning the cut guiding portion adjacent to the target bone, wherein the mounting portion and the cut guiding portion are positioned in a predetermined spatial relationship relative respectively to the adjacent and target bones; and making a cut in the target bone using a saw, the saw being guided along a predetermined path by the cut guiding portion. | 2020-12-31 |

20200405324 | HARVESTING CANCELLOUS BONE AND MARROW FROM INTRAMEDULLARY CANAL FORMED IN MEDULLARY CAVITY USING BONE PRESS APPARATUS - Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer. | 2020-12-31 |
20200405325 | BONE GRAFT HARVESTING - The present disclosure includes apparatuses for a bone graft harvesting device. An example apparatus includes a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated and a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole. | 2020-12-31 |
20200405326 | SECURING A BONE GRAFT TO THE GLENOID BONE AND IMPLEMENTATIONS THEREOF - A method of securing a bone graft to an anterior surface of a patient's glenoid bone, including drilling first and second bores through a posterior surface to an anterior surface of the glenoid bone; measuring a medial distance of the first bore; transferring the medial distance to a bone block; drilling a third bore based on the medial distance through the bone block to match the first bore; positioning the bone block in contacting relation with the anterior surface of the glenoid bone, and coaxially lining up the third bore with the first bore; positioning a first fastener through the third bore and the first bore; drilling a fourth bore in the bone block by positioning a drill bit through the second bore from the posterior side of the glenoid bone, and extending the drill bit from the first surface of the bone block to the second surface of the bone block; and positioning a second fastener through the fourth bore and the second bore. | 2020-12-31 |
20200405327 | GUIDING DEVICE AND METHOD OF USING THEREOF - A bone drill guiding device including a drill entry part comprising a cannula having a distal end portion and sized to receive a bone drill, a drill exit part comprising a fixation tip portion and a coupling that rigidly couples the drill entry part and the drill exit part so that longitudinal axes of the cannula distal portion and the fixation tip portion are arranged on a single mutual axis. In some embodiments, the coupling is a linear sliding coupling that parallels the single mutual axis. | 2020-12-31 |
