ABSTRACT:
An anti-siphon device limits the flow of a fluid from a first region of a patient's body to a second region. The device includes a housing having a spherical inner surface with a predetermined inner diameter. The housing has an inlet port for receiving fluid from the first region and an outlet port for directing fluid to the second region. The inlet port and the outlet port are disposed approximately diametrically opposite from each other. A spherical ball is disposed within the housing. The spherical ball has a ferromagnetic weight disposed off center therein. The spherical ball has an outer diameter that is less than the inner diameter of the housing so that the spherical ball is free to rotate within the housing and the fluid is free to flow between the inner surface of the housing and an outer surface of said spherical ball. The spherical ball has a circumferential recess extending through its center.
