| | Ventricular system - Wikipedia, the free encyclopedia |
 | | The ventricular system is a set of structures in the brain continuous with the central canal of the spinal cord. | | | This became the first "evidence" that mental illness was biological in origin and led to a reinvigoration of the study of such conditions via modern scientific techniques. | | | CSF within the spinal cord can flow all the way down to the lumbar cistern at the end of the cord around the cauda equina where lumbar punctures are performed. |

| | In operation, the ventricular catheter 10 is inserted through the burr hole 14 of the skull by well-known surgical techniques, and the drainage catheter 21 is inserted into, e.g., the patient's jugular vein. | | | This invention relates to ventricular shunt systems, and more particularly to a dual pressure shunt valve assembly which may be operated to maintain either one of two cerebro spinal fluid pressures in the ventricles of a patient's brain. | | | In addition to the forces developed by the CSF pressure, the brain tissue is subjected to a counterforce developed by the venous pressure within the intraparenchymatous system, within the brain tissue itself. |

| | Ventricular Assist Device FAQ |
| | A ventricular (or cardiac) assist device is used when a patient in heart failure has exhausted the usual therapies of medical and surgical care. | | | The primary component of the system, the blood pump, is surgically placed just below the diaphragm and connected to the left ventricular chamber of the natural heart to receive the patients blood. | | | It is a mechanical aid to heart function and helps restore blood flow to the body that the damaged heart is unable to supply. |
