20100312084 | Systems and methods for lumbar cerebrospinal fluid access and treatment - A system and method for accessing and treating the cerebrospinal fluid with a multilumen catheter configured for placement along a cerebrospinal fluid pathway and a subcutaneous, dual reservoir/pump. The subcutaneous dual reservoir/pump allows simultaneous, bidirectional cerebrospinal fluid access and cerebrospinal fluid exchange. The two chambers prevent mixing of newly treated and discardable cerebrospinal fluid. The subcutaneous dual reservoir/pump can be used inline with other cerebrospinal fluid devices. The catheter may be coupled with a medical probe that sends a wire to a computational device, which can then send wireless data and receive wireless instructions. A method of assessing cerebrospinal fluid infections is provided, whereby monitoring of the cerebrospinal glucose concentrations with a cerebrospinal glucose sensor and analysis of the data by a computational device can notify a patient or medical provider of an impending infection. This assembly can help better diagnose and treat injury and disease. | 12-09-2010 |
20120095383 | SYSTEMS AND METHODS FOR AN ADVANCED MEDICAL DEVICE - The present invention relates to a biologically active medical device, which includes a matrix seeded with progenitor cells, and then covered by ciliated tissue. The matrix is capable of enabling cellular migration. The ciliated tissue is ependymal cells that express at least one of tight junctional complexes, zonula adherens, and gap junctions. The progenitor cells include subpendymal progenitor cells. In some cases the progenitor cells include stem cells, and the ciliated tissue includes at least one of Choroid cells, tanacytes, and circumventricular organs. In some embodiments, the medical device is oriented into a tubular structure in order to form a cerebrospinal shunt. Additional cells and structures may be imbedded within the matrix, such as glia, endothelial cells, stem cells, and blood vessels. The medical device may also be incorporated into a bioreactor including a flexible inner tube defining an anthropomorphically shaped lumen. | 04-19-2012 |
20120271168 | SYSTEMS AND METHODS FOR A COMPUTATIONAL MEDICAL DEVICE IN DYNAMIC BODY SYSTEMS - A computational catheter device including at least one lumen, pressure sensor(s), external sensor(s), a signal modeler, and a signal analyzer is provided. The pressure sensor generates a pressure signal for a dynamic body system, whereas the external sensor determines the fundamental frequency caused by cardiovascular pulsation or external oscillator. The signal modeler uses catheter location and the fundamental frequency to generate a predicted signal. This predicted signal may be compared to the actual pressure signal by the signal analyzer to generate a calibration. This calibration may include any of a measure of perivascular state, a waveform output which causes standing waves within the dynamic body system, a boundary condition for safe operations, and an indication of abnormal physiology for assistance in catheter navigation. The catheter device may also include an actuator which uses the calibration to achieve homeostasis by fluxing fluids and/or guiding catheter movements. | 10-25-2012 |
20140180416 | SYSTEM, METHOD AND APPARATUS FOR SIMULATING INSERTIVE PROCEDURES OF THE SPINAL REGION - Sensor information is received that indicates insertion of an insertion mechanism into a mechanical body. A virtual representation of the spinal region is generated. The insertion mechanism is represented graphically, as part of the virtual representation, as the insertion mechanism is inserted into the mechanical body | 06-26-2014 |
