A percutaneous access device implantable beneath the skin of a patient which includes a housing having a flange positionable beneath the skin and neck projecting outward through the skin. The percutaneous access device includes electrical communication through the flange and fluid access through the flange. The components providing fluid access and electrical communication are removable through the neck portion of the implant for testing and service as required without the need for further surgery on the patient. A turret body is received within the hollow interior of the neck having a fluid channel extending therethrough and containing current limiting devices securely disposed within the turret body.

DETAILED DESCRIPTION The percutaneous access device of the present invention includes a housing implantable within the patient and a turret assembly adapted to be removably fastened within the housing.
The turret assembly contains at least one portion of a current conveying device which transfers current through the PAD to and from external sources.
As embodied herein, the turret assembly includes at least one current limiting device as well as various contacts and mechanical mounting mechanisms adapted to matingly and positively attach to an externally located lead.
The turret assembly also includes means for permitting the flow of fluid, such as a liquid or gaseous material, through the PAD to and from an externally attached device.
