40. A method of draining cerebrospinal fluid comprising:
-
installing, in a patient having excess cerebrospinal fluid in his or her cranial cavity, a cerebrospinal fluid drainage device comprising at least three tubes and a distributor that connects said at least three tubes, wherein said at least three tubes comprise a supply tube, a first discharge tube, and a second discharge tube; draining cerebrospinal fluid from the head of a patient through said supply tube toward said distributor; shifting a rotary device of said distributor to a first position, and thereby flowing cerebrospinal fluid from said supply tube, through said distributor, and to said first discharge tube, and blocking flow of cerebrospinal fluid to said second discharge tube; and upon formation of a blockage of flow in said first discharge tube, shifting said rotary device to a second position, and thereby flowing cerebrospinal fluid from said supply tube, through said distributor, and to said second discharge tube, and blocking flow of cerebrospinal fluid to said first discharge tube. - View Dependent Claims (41, 42, 43, 44, 45)

46. A method of draining cerebrospinal fluid comprising:
-
installing, in a patient having excess cerebrospinal fluid in his or her cranial cavity, a cerebrospinal fluid drainage device comprising at least three tubes and a valve that connects said at least three tubes, wherein said at least three tubes comprise a first supply tube, a second supply tube, and a discharge tube; draining cerebrospinal fluid from the head of a patient through said supply tubes toward said valve; shifting a movable distributor of said valve to a first position, and thereby flowing cerebrospinal fluid from said first supply tube, through said valve, and to said discharge tube, and blocking flow of cerebrospinal fluid from said second supply tube; and upon formation of a blockage of flow in said first supply tube, shifting said movable distributor to a second position, and thereby flowing cerebrospinal fluid from said second supply tube, through said valve, and to said discharge tube, and blocking flow of cerebrospinal fluid from said first supply tube. - View Dependent Claims (47, 48)

49. A device for draining cerebrospinal fluid comprising:
-
at least three tubes comprising a first supply tube configured to receive cerebrospinal fluid, a second supply tube configured to receive cerebrospinal fluid, and a discharge tube configured to discharge cerebrospinal fluid; a valve configured to control flow of cerebrospinal fluid; said at least three tubes being connected by said valve; said valve comprises a movable distributor which is shiftable between; a first position in which said movable distributor permits flow of cerebrospinal fluid from said first supply tube to said discharge tube, and blocks flow from said second supply tube; and a second position in which said movable distributor permits flow of cerebrospinal fluid from said second supply tube to said discharge tube, and blocks flow from said first supply tube. - View Dependent Claims (50)
