The device of the present invention includes a modular, implantable catheterization port that is composed of a body portion, an interior port and an exterior port. The interior and exterior ports are selectively attachable to the body portion such that the device can be assembled by a clinician at the skin entry site without compromising the position of other portions of the device within and outside of the patient. The device further includes a first skirt and a second skirt that surround the exterior port at its junction with the body portion. Both skirts are designed to gradually affix themselves into the surrounding tissues of the patient's body during the initial phase of healing. The first skirt is composed of a bio-absorbable material such that in subsequent phases of healing its connection to the surrounding tissues diminishes, leaving the second skirt to maintain a mature, secure, and permanent connection to the tissues. The bio-absorbable material can be selected prior to assembly in order to ensure that the first skirt is fully absorbed at the conclusion of the procedure, thus permitting an easy and less-invasive removal of the device from the patient.
