ABSTRACT:
This invention is an improvement in an anchor for a transcutaneous conduit, such as a hypodermic needle, used in conjunction with a subcutaneous reservoir having a conduit-penetrable septum. The anchor includes a resilient protective boot having a plurality of concentric annular rings stacked using the conduit as an axis, beginning with a base ring carrying adhesive for attachment to the skin of a living body and ending with a terminal ring to be attached to the conduit, and includes means, when the terminal ring is attached to the conduit, to urge the protective boot into a compressed state along the axis and the conduit into the body. The improvement provides means for inserting a stylet into the anchor and through the conduit to prevent coring the septum when the conduit is inserted into the reservoir.
