A medical catheter assembly including a multi-piece connector. In one embodiment, the medical catheter assembly is a PEG implanting assembly comprising a tubular dilator and a silicone feeding tube having an internal bolster at its rear end. The assembly also comprises a multi-piece connector comprising an inner ring, a fitting and an outer ring. The inner ring has an outer diameter greater than the inner diameter of the feeding tube and is coaxially disposed within the feeding tube by a friction-fit. The fitting comprises a front portion, an intermediate portion and a rear portion, the intermediate portion including a shoulder having an outer diameter greater than the inner diameter of the feeding tube. The front portion of the fitting is inserted through the rear end of the dilator and is secured to the dilator by a plurality of barbs. The shoulder and the rear portion of the fitting are inserted into the feeding tube through its rear end, with the rear portion of the fitting being inserted into the inner ring and secured thereto by mating threads. The outer ring is inserted over the feeding tube and is positioned between the shoulder and the inner ring, the outer ring being sized to securely retain the feeding tube between the outer ring and the inner ring and between the outer ring and the shoulder.

A device and method of loading a bone anchor into a bone-anchor inserter does not apply force on the leading point, the distal cutting edges or threads of the bone anchor. The bone-anchor loading device may, for example, include a main body including a gripping portion and, projecting therefrom, an elongated bone-anchor receiving member having a receiver fitting at a distal end thereof; an elongated sleeve coaxially disposed over the anchor-receiving member and configured for slidable translation thereover; and an interference fitting causing engagement between the sleeve and the anchor-receiving member when the sleeve is translated to an interference position with respect to the main body, the engagement further causing the receiver fitting to deform to releasably secure a bone anchor.
