Port catheter
First Claim
1. A port catheter for implantation in a body comprising a casing (1) having a generally cylindrical wall and having a chamber (22) therein, which is sealed on one side by a needle-pierceable membrane (4) and which is connected at (the) an end of the casing opposite from said (on the) membrane (4) with a tube catheter (8), and a cone (7) on the casing (1) that allows the implantation of the port catheter by puncture, and two anchoring loops (9,10) that protrude from the casing wall and can be bent together, the anchoring lops (9,10) comprising a spring wire which embraces the casing (1) over one position, protrudes from this position in two opposing directions taking the form of said two anchoring loops (9,10) and which (meet) meets again to embrace the casing (1), at a second position axially separated from the first position.

Abstract
A port catheter, designed to be implanted by puncturing, has a cylindrical casing (1) in which there is a chamber (22) dosed off on one side by a membrane (4) which can be punctured by an injection needle and connectable on the other side to a catheter (8). Securing loops (9, 10) project from the casing (1) and can be folded together by special means during insertion and unfold when the means are released. The securing loops (9, 10) are made of spring wire surrounding the casing (1) at two separate points. The securing loops (9, 10) are thus relatively stiff in the securing direction but can be bent circumferentially about the casing (1) and held in this position for implantation.
