ABSTRACT:
A percutaneous access port for providing access to a selected organ in an animal which includes a base assembly and a septum assembly. The base assembly has a fluid chamber formed in a portion thereof generally between an upper and a lower end of the base assembly with an inlet port being formed in a portion in the base assembly generally near the lower end of the base assembly. The inlet port is adapted to be connected to the selected organ to provide communication between the fluid chamber in the base assembly and the selected organ. At least one access port is formed through the upper end of the base assembly with each access port extending a distance through the base assembly and intersecting the fluid chamber to provide communication between the upper end of the base assembly and the fluid chamber. The septum assembly includes a portion which extends across each access port in the base assembly to resealably seal each access port, each access port providing resealable access to the fluid chamber. A transducer is disposed in the fluid chamber of the base assembly and the transducer is adapted to detect the pressure of the fluid within the fluid chamber and to provide an output transducer signal indicative of the pressure of the fluid in the fluid chamber, the transducer providing output signal continuously providing an output indication of fluid pressure in an implanted condition of the base assembly with the transducer connected thereto.
