Abstract: Systems and devices for controlling saliva production by a salivary duct. An exemplary system includes a saliva control device and means for applying a vacuum to a salivary duct to allow attachment of the device over a salivary duct. One such means comprises a hand-held manually actuable pump apparatus. The apparatus can be operated using a single hand. One embodiment of the saliva control device includes an elastic body comprising at least one elastomer and a constriction hole formed through the elastic body. The stiffness of the elastic body and/or the diameter of the constriction hole are configured to provide a degree of constriction to a salivary duct sufficient to prevent a flow of saliva from the duct without cutting off blood flow to tissue surrounding the salivary duct.

Abstract: A hand-held vacuum pump apparatus for use in attaching one or more saliva control devices over one or more selected salivary ducts. The apparatus can be operated using a single hand. The apparatus includes a body having a grippable handle and a support member, a hollow suction tube supported by the support member of the body, a plunger slidably disposed within the hollow suction tube, and means for proximally moving the plunger within the hollow suction tube in response to squeezing a practitioner's hand and/or at least one finger.

Abstract: A saliva control device for controlling or isolating the production of saliva by a salivary gland. The saliva control device includes a body, a cavity formed in the body for forming a seal over the salivary gland, a vacuum chamber in the body that assists the cavity in forming a seal, and an air evacuation passage. The air evacuation passage is used to selectively apply and then maintain a vacuum to the vacuum chamber and cavity.
