VENTURA Hydrocephalus Implant Valve 의 안전성 경고

Valves for hydrocephalus are implant devices used in the surgical treatment of hydrocephalus, to derive the CSF (cerebrospinal fluid) from the ventricles into the peritoneal cavity or to other drainage sites appropriate for a particular patient. Sondispositives produced in medical grade silicones and material-thermoplastic with unrestricted implantability, intended for use in patients with hydrocephalus. The external ventricular drainage catheter with anti-siphon mechanism (CSF "cerebrospinal fluid" / MAS "anti-siphon mechanism") is indicated in temporary relief of intracranial hypertension for any etiology that causes a disturbance in the absorption of the flow of CLL, whether in subarachnoid hemorrhages, interventricular, hydrocephalus, and primary brain tumors. The anti-siphon mechanism has an internal design, which allows the LCR to flow inside without offering additional resistance to the drainage system, and when a negative pressure occurs in the distal part of the system (fall of the bag to the floor, for example), the The anti-siphon mechanism is activated and blocks the sudden emptying of the cerebral ventricles. The external drainage systems are used to drain the cerebrospinal fluid (produced inside the cerebral ventricles) into a collecting container located externally of the human body. These systems are relatively widely used in neurosurgical procedures and, in general, are composed of a
