1. A catheter for realising a volume flow into or out of a human or animal organ, comprising a catheter tube and, at a distance from a distal end of the catheter, an affixer that mechanically affixes the catheter in tissue of the human or animal organ, said affixer sized and shaped to fit and attach inside tissue of the organ;
- wherein said catheter tube is selectably releasable and detachable from said affixer when said affixer is positioned in the tissue, whereby the affixer has an aperture therethrough, said aperture sized and shaped for said catheter tube to pass therethrough;
wherein the catheter is designed in such a manner that the affixer abandons an affixing effect when a specific tensile force of at most 30 N acts on the catheter tube;
wherein the catheter comprises a distal form element over or on the catheter tube, in relation to a position of the affixer, of which an inner diameter is larger than an outer diameter of the catheter tube, wherein the affixer is designed in such a manner that, due to the specific tensile force acting on the catheter tube, said affixer expands on an edge of said catheter tube facing towards the catheter tube and the form element in such a manner that the catheter tube can be drawn together with the form element through the affixer.
