First Claim
1. A percutaneous access device for implantation within a patient having at least a portion projecting outwardly through a skin of the patient comprising:
- housing means for defining at least one chamber, the housing means having a flange portion positionable beneath the skin of the patient and an outwardly extending neck portion disposable passing through the skin of the patient;
at least one fluid conduit means and at least one electrical conduit means, each conduit means for communicating from an external position with respect to the patient to an internal position with respect to the patient, each of the conduit means passing through the neck portion and flange portion of the housing and in communication with the at least one chamber defined by the housing means; and
means for externally removing at least a portion of each of the conduit means through the neck portion of the housing means.

Abstract
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.

4. A percutaneous access device for implantation within a patient having at least a portion projecting outwardly though a skin of the patient comprising:
-
housing means for defining at least one chamber, the housing means including a flange body having an upper wall orientatable toward the skin of the patient and a lower wall opposed to the upper wall, the upper and lower wall defining the at least one chamber in a central interior region, the flange body further having a first passage in communication between the at least one chamber in the central interior region and the exterior of the flange body, and a second passage extending external to the housing from the at least one chamber, a neck integrally formed with the upper wall of the flange body and projecting outward therefrom, the neck defining at least in part the chamber within the central interior region, the chamber having an internal surface, the neck terminating in an end region projectable above the outer surface of the skin of the patient, the end region having an outer end opening opposed to the lower wall of the flange body; means for electrically communicating from a position external with respect to the patient to a position internal with respect to the patient, the electrical communicating means passing through the flange body and having at least one electrically conductive conduit associated therewith; means for fluidly communicating from the position external with respect to the patient to the position internal with respect to the patient, the fluid communicating means passing through the interior region in the flange body and having at least one fluid conduit associated therewith; and means for removably positioning at least one of the fluid communicating means and the electrical communicating means within the housing means. - View Dependent Claims (5, 6, 7, 8, 9, 10)
