20110054380 | Method and apparatus for removal of gas bubbles from blood - A system is disclosed for removing gas bubbles from blood during circulatory assist procedures. Such bubbles are generated, along with particulate matter, in an extracorporeal circulatory bypass system by the pump, oxygenator and other components. Filters are used in the line to remove particulates and bubbles from the blood before they are pumped back to the patient but current filters are inefficient at removing small bubbles and debris that can cause neurological defects and renal and other organ failures in the patient. An active filter apparatus and method is disclosed that forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter. The filter comprises an axially elongate cylindrical shell with a blood inlet, a blood outlet and a gas outlet. A motor driven impeller spins the blood within the shell and forces the gas toward the center by centripetal force, utilizing the buoyancy effects of the bubbles in blood, whereby the bubbles can be bled off at the center of the filter element. | 2011-03-03 |

20110054382 | CEREBROSPINAL FLUID EVALUATION SYSTEM HAVING THERMAL FLOW AND FLOW RATE MEASUREMENT PAD USING A PLURALITY OF CONTROL SENSORS - A method and device for testing for the presence, absence and/or rate of flow in a shunt tubing implanted under the skin by using a measurement pad having a plurality of temperature sensors, one of which is aligned with the shunt and the other sensors being symmetrically displaced on either side of the first temperature sensor in a direction transverse to the shunt tubing. These “outer” temperature sensors act as control temperature sensors. A temperature source, e.g., a cooling agent, positioned within an insulated enclosure, is then applied at a predetermined location on the measurement pad that is insulated from the temperature sensors. The movement of this temperature “pulse” is detected by the shunt-aligned temperature sensor via the shunt tubing as the CSF carries the temperature pulse while the control sensors detect the pulse via convection through the skin. The temperature data from these sensors are provided to a CSF analyzer that determines a CSF shunt flow status or flow rate. | 2011-03-03 |

A system for repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of bone cement components and an inner lumen for passage of a mixing element; an internal bone fixation device releasably engaging the distal end of the delivery catheter, wherein the internal bone fixation device moves from a first compact state to a second expanded state when the bone cement components are delivered to the internal bone fixation device and mixed within the internal bone fixation device; and a spinning mechanism engaged to a rotatable shaft, wherein the spinning mechanism is inserted into the internal bone fixation device. | 2011-03-03 |
20110054481 | Delivery Containers and System - A containment system for delivery of prepackaged substances to locations within a living individual that can be used in combination with existing cannulae used for this purpose is provided. The substance delivery containers are formed from a containment module; and a substance to be delivered into a specific location of a living individual disposed within the containment module. Prior to use, the containment module maintains a seal around the substance to prevent leakage and to isolate the substance from the surrounding environment. The containment module is formed from a material that is flexible and compressible and has structure and shape sufficient to define a distal end and a proximal end. The proximal end includes a shaped receiver for interacting with a tamp or similar pushing device for driving the containment module and/or the substance contained therein through a cannula to the desired location within the living individual. | 2011-03-03 |
20110054482 | COMPOSITES AND METHODS FOR TREATING BONE - A system and method for treating bone abnormalities including vertebral compression fractures and the like. In one vertebroplasty method, a fill material is injected under high pressures into cancellous bone wherein the fill material includes a flowable bone cement component and an elastomeric polymer component that is carried therein. The elastomer component can further carry microscale or mesoscale reticulated elements. Under suitable injection pressures, the elastomeric component ultimately migrates within the flowable material to alter the apparent viscosity across the plume of fill material to accomplish multiple functions. For example, the differential in apparent viscosity across the fill material creates a broad load-distributing layer within cancellous bone for applying retraction forces to cortical bone endplates. The differential in apparent viscosity also transitions into a flow impermeable layer at the interface of cancellous bone and the flowable material to prevent extravasasion of the flowable bone cement component. | 2011-03-03 |
