| 1996 | Invention patented by Rajko Kenda on December 2nd, 1996. Abstract: The invention relates to a catheter, particularly a permanently implanted catheter, particularly a peritoneal-dialysis one, particularly for such peritoneal dialysis where a catheter tube is positioned normally to the surface area at the location of implantation, which catheter consists of a flexible catheter tube and at least one cuff, which is stable in its position on the catheter tube. The catheter tube provides a length segment (A) beginning next to the patient's skin, the general flexibility of the said length segment being greater than that of the remaining length section of the catheter, so that the catheter tube protruding from the patient's abdomen easily bends at the said length segment without collapsing (being squeezed). In a basic embodiment of the invention, the length segment (A) of the catheter consists of a main tube (1) and two mantle tubes (2, 3) fitted individually onto each length section of the said main tube so that a spacing exists between them, whose length corresponds to the said length segment (A), with reinforcing rings (4) being arranged on the main tube (1) in the region of the said length segment (A). The invention foresees several variant embodiments. Further, the invention relates to a novel use of a flexible tube as means for providing a length segment, whose flexibility in comparison to that of the remaining length section(s) of a tube assembly is intentionally accentuated. |
