Abstract
Implantable infusion apparatus comprising a chamber sealed by a septum and having an outlet aperture leading therefrom, to which a catheter tube is connected. A wire anchored in the chamber base projects into the catheter lumen, forming a ring slot whose diameter is smaller than the average size of a punched out particle. The wire thus serves as a particle retention means.
