  • Patent number: 5356381
    Abstract: An access port (10) for implantation adapted for providing repeated access to specific tissue within a patient and communicating with the tissue by an internal implanted catheter (52). The access ports according to this invention incorporate an enlarged entrance orifice (13) with a funnel shaped internal cavity that narrows down to a reduced diameter passageway (18). An articulating catheter valve (24) is provided within the passageway which normally prevents the flow of fluids through the valve but which can be penetrated by an external introduced filament (32) such as a catheter. After implantation, an external filament (32) is introduced into the port (10) and guided by the passageway into registry with the catheter valve (24). Continued feeding of the filament (32) causes the filament to pass through the valve (24). Thereafter, with a catheter (32) inserted, therapeutic agents can be infused into the patient, or body fluids can be withdrawn.

  • Patent number: 5335655
    Abstract: A suction control valve is disclosed which includes a primary suction device access and an ancillary suction device access. The valve includes an actuator which is movable between a first position in which the primary access is closed against suction pressure therethrough, to a second position in which the primary access is open to suction pressure therethrough, or alternatively, to a third position in which the primary access port remains closed to suction pressure therethrough and the actuator becomes locked against movement into the second position. When the actuator is in the first position, atmospheric air can pass through the valve and into the suction pressure source in such a manner that a "hissing" auditory signal is generated, indicative of the presence of suction pressure within the valve. When the actuator is in the second or third positions, the "hissing" is prevented.

The pouch includes an inlet/outlet valve for providing communication between the interior of the pouch and the atmosphere of the interior of the pouch and a drainage tube. The box-like internal body structure is capable of being in an engaged position or in a disengaged position. In the disengaged position, the internal box-like structure can remain in a flat condition without causing the tensioning member to be stretched or activated. When ready for use, the internal structure can be manually expanded into its box-like structure. When fully expanded the internal structure will become engaged, hence engaging the tensioning member. Subsequent compression of the internal structure to its flat position stretches the tensioning member and activates the evacuator.
