Zusammenfassung:Disclosed is a compact, low profile venous access port to be implanted below the skin of a patient and coupled to a (e.g., subclavian) vein by a Seldinger technique, or the like, so that a supply of fluid medication can be delivered directly to the patient's circulatory system via a medication delivery lumen. The target axis of the venous access port herein disclosed advantageously makes a small acute angle with to the patient's skin (as opposed to the 90 degree angle that is common to conventional subcutaneous ports) so as to avoid puncturing a medication delivery lumen as a consequence of a misalignment of a needle cannula with the target area of the port. A pocket forming tool is also disclosed to be inserted through an incision made in the patient's skin to create an accurately sized anti-migration pocket that is closed around the venous access port to prevent a displacement thereof. Following implantation, anti-migration barbs which project from the venous access port attach to the patient's superficial muscular facia to hold the port in place without the use of sutures. Accordingly, the venous access port of this invention may be ideally implanted (by a radiologist) on an outpatient basis without the cost and recovery time often associated with a surgical procedure performed by a surgeon in an operating theater.
