A subcutaneously-implanted infusion device that has a portal defining an inner reservoir chamber that allows communication between a septum and an end of a catheter tube connected to the portal. The septum is mounted in a compressed state within a main housing of the portal by a pressure-insert element that is formed against the septum by an arbor press. The septum is then held in its compressed state via a retaining ring cooperating with an annular groove provided in the interior surface of the main housing directly adjacent the lower end of the portal. The device also includes a lower suture-attaching cuff having a skirt portion, with a low profile angle, which is provided with a plurality of separate, spaced-apart, suture-reinforcing tabs. The pressure-insert element is provided with a through-hole for the passage of a catheter with an enlarged abutment stop at one end for preventing passage of the catheter through the through-hole. Medical glue to used to bond the end of the catheter to the interior surface of the pressure-insert element. A protective metal sleeve is mounted about the portion of the catheter directly adjacent the outer circumference of the pressure-insert element for protecting against accidental puncture of the portion of the catheter which extends from the through-hole.
