Patent application numberDescriptionPublished
20080214982FLUID MANAGEMENT FLOW IMPLANTS OF IMPROVED OCCLUSION RESISTANCE - This invention relates to achieving or improving uniform distribution of fluid flow in medical devices such as when combined with antibiotics impregnated in a catheter and/or with a drug-eluting catheter to further inhibit the catheter from becoming occluded by debris in the CSF or by bacterial biofilm formation or tissue proliferation in the catheter.09-04-2008
20090005701Cradled Sensor Assembly - Various methods and devices are provided for removably coupling a sensor assembly to a catheter to measure conditions surrounding the catheter when the catheter is implanted in a patient. In one embodiment, a modular sensor assembly is provided and includes a housing having an antenna therein adapted to be removably coupled to at least a portion of a catheter. The housing can be a closed loop having an opening therethrough. One or more sensors can be coupled to the antenna for measuring conditions surrounding the catheter when the catheter is implanted in a patient. In one embodiment, the housing can be adapted to removably couple to a distal end of the catheter, and the opening of the housing can be adapted to receive the catheter. The antenna can be a loop disposed within the housing.01-01-2009
20100286585Shunt Delivery of Curcumin - A method for reducing or preventing a human brain disorder relating to the presence of a pathogenic substance in cerebrospinal fluid by selecting a human for treatment as a patient and placing a proximal end of a first catheter, having at least a first lumen, in a first sub-dural location within the brain of the patient to establish open communication between the first lumen and cerebrospinal fluid of the patient. For an extended period of time, a curcumin agent selected from at least one of curcumin, a curcumin hybrid and a curcumin analog is delivered to the cerebrospinal fluid to interact with the pathogenic substance to attenuate its effect on the brain.11-11-2010

20080214983PRESSURE SENSING VALVE - A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.09-04-2008

20090270759System and Method for Measuring the Pressure of a Fluid System Within a Patient - A pressure sensing apparatus has a pressure sensor component that includes a pressure sensing port, a pressure sensor for sensing a pressure of a fluid in the pressure sensing port, and a digital processor communicating with the pressure sensor for performing calculations involving fluid pressures sensed. The pressure sensing apparatus further includes a first chamber in fluid contact with the pressure sensing port, a second chamber fluidically connectable with a patient's cerebrospinal fluid system, and a membrane located between the first and second chambers so as to transmit fluid pressure from the second chamber to the first chamber.10-29-2009
20100010415HIGH PRESSURE RANGE HYDROCEPHALUS VALVE SYSTEM - A valve for use in a shunt system to drain fluid from one part of a patient's body to another is provided. In an exemplary embodiment, the valve is operable at a threshold pressure that is selectively adjustable up to at least about 400 mm H01-14-2010
20100210992MULTI-BRANCHED ANTI-REFLUX VALVE - A shunt system includes a first catheter and a second catheter, each having a proximal end and a distal end, and at least one opening adjacent to its distal end. A proximal end of a drainage catheter is in fluid communication with the proximal end of the first catheter and the proximal end of the second catheter. A first one-way valve is disposed in fluid communication with the first catheter between its proximal end and its at least one opening. The first one-way valve effectively blocks fluid flow from the proximal end to the at least one opening. A second one-way valve is disposed in fluid communication with the second catheter between its proximal end and its at least one opening. The second one-way valve effectively blocks fluid flow from the proximal end to the at least one opening.08-19-2010
