The device and methods may be utilized for the patient-specific diagnosis and/or treatment of a disease state which presents an associated molecule or protein in plasma or any other fluidized physiological system. | 03-13-2014 |
| 20140081193 | METHOD AND SYSTEM FOR ADJUSTING ROTATION SPEED OF AN EXTRACORPOREAL THERAPEUTIC DEVICE - An extracorporeal therapeutic device automatically controls a rotation speed of a centrifuge for processing whole blood. Separation of whole blood components is achieved with minimal thermal contribution to blood temperature from the motor control mechanism that rotates the centrifuge and from aerodynamic drag on the rotating centrifuge. | 03-20-2014 |
| 20140303542 | Method and device for treating cancer - A method and device treats cancer where blood from a cancer patient passes through an array of passageways within an interior of a chamber. The passageways include wells having porous membrane wall portions that enable a molecular-sized activating agent in a carrier fluid that enhances an immune response to pass through these porous wall portions. Pore size is such to allow the molecular-sized activating agent in the interior of the chamber to enter the wells yet prevents immune cells and cancer cells in the wells to pass through the porous wall portions into the interior of the chamber. Blood is retained in the wells so that it remains in contact with the immune cells and cancer cells for a predetermined period sufficient to enhance an immune response. Then the cells with an enhanced immune response are return to the patient. | 10-09-2014 |

| 20150335805 | METHOD FOR ASSESSING A PATIENT'S FLUID STATUS AND/OR SENSITIVITY TO FLUID REMOVAL, CONTROLLER, AND DEVICES - The present invention relates to a method for assessing a patient's sensitivity to fluid removal from the patient's vascular system or to fluid replacement or addition with regard to the patient's hydration state, the method comprising the step of determining a value reflecting the distribution of fluid between at least two distribution spaces of the body of the patient or changes thereof from measured or calculated values, and assessing whether the value fulfils at least one criterion. It also relates to a controller, an apparatus, a device, a digital storage device, a computer program product, and a computer program. | 11-26-2015 |
| 20160038667 | SYSTEMS AND METHODS FOR DESTROYING CANCER CELLS IN BLOOD - An apparatus for destroying cancer cells in blood includes a vessel for accepting a flow of blood of a patient through the vessel, and a sound energy source coupled with the vessel for generating sound energy at a resonant sweep frequency that causes cancer cells, within the flow of blood in the vessel, to act as cavitation nuclei and implode without implosion of other cells not resonant with the resonant sweep frequency. A method for destroying cancer cells in blood includes circulating blood from a patient through a vessel coupled with a sound energy source and exposing the blood, when passing through the vessel, to sound energy at a resonant sweep frequency to make cancer cells therein act as cavitation nuclei and implode without implosion of other cells not resonant with the resonant sweep frequency. | 02-11-2016 |
| 20160067472 | CATHETER ADAPTER APPARATUS - A catheter adapter apparatus includes an adapter body. The adapter body includes a fluid source end adapted for connection to a fluid source and having an internal bore to transfer the fluids supplied by the fluid source, and a catheter end for connection to a catheter tube. The catheter end includes first and second members. Each of the first and second members is adapted for reception within corresponding lumens of the catheter tube. At least the first member defines an internal bore in fluid communication with the fluid source end to transfer the fluids supplied by the fluid source. | 03-10-2016 |
| 20160095971 | METHOD AND DEVICE FOR MONITORING EXTRACORPOREAL BLOOD FLOW - A method and a device for monitoring an extracorporeal blood flow during an extracorporeal blood treatment with an extracorporeal blood treatment device. The extracorporeal blood treatment device may include the device for monitoring an extracorporeal blood flow. The arterial and/or venous patient access is monitored with a first and a second method, each of which there is a check for a presence of at least one criterion that is characteristic of a condition of the vascular access that is not in proper order, the criteria for the first and second methods being distinguished from one another. A blood pump, which is preferably an occlusion blood pump, is stopped once the presence of the at least one criterion of the first method has been established, while a venous cut-off unit remains open. Once the blood pump has been stopped, the presence of the at least one criterion is checked with the second method. The venous cut-off unit is not closed until the at least one criterion for the second method is present. Otherwise the blood pump is restarted to continue the blood treatment. | 04-07-2016 |
| 20160158431 | FILTERING OF PRESSURE SIGNALS FOR SUPPRESSION OF PERIODIC TABLES - A filtering device receives a pressure signal (P) from a pressure sensor in a fluid containing system, the pressure signal (P) comprising first pulses originating from a first periodic pulse generator and second pulses. The device acquires a reference signal which is indicative of a current operating frequency of the first periodic pulse generator. The device identifies, based on the reference signal, a plurality of harmonics ( | 06-09-2016 |
