ABSTRACT:
An implantable intravascular access system, including an implantable, catheter obturator controller manifold for use with an implantable intravascular catheter. The catheter includes a lumen, having an expanded state and a normal state, an obturator, and an obturator plenum having an inflated state and a contracted state. The lumen can be closed or opened by hydraulically actuating the expansion or contraction of the obturator plenum when the lumen is in its normal state. When the obturator plenum is expanded to its inflated state, the obturator substantially blocks the lumen such that substantially no fluid can pass through the lumen when the lumen is in its normal state. The manifold comprises a housing, a receiving mechanism for receiving the catheter, an actuating mechanism for hydraulically actuating the expansion or contraction of the plenum, and a first entry mechanism for entering the housing.
