Abstract
A valve apparatus comprising a tubular body having a lumen therethrough and which is adapted for accessing the cardiovascular or other intravenous system of a patient. The body includes a compression chamber communicating with the lumen and adapted to cooperate with a seal. The compressible seal being configured to selectively seal and unseal the lumen in response to a compressive force acting on the seal. The seal having a longitudinal passageway therethrough that communicates with the lumen and is selectively sealed and unsealed in response to changes in the compressive force generated by a plunger assembly. The plunger assembly is configured to apply a certain amount of compressive force on the seal via the engagement of a rotating member and an engagement member under the influence of a rotating end cap. A selecting mechanism comprising a selecting lever and a selecting assembly is movably coupled to the tubular body and communicates with the plunger assembly. The selecting mechanism is configured to selectively vary the compressive force applied by the plunger assembly on the compressible seal, thereby moving the seal from a selectively adjusted position or inactivated positio…
