摘要：
According to the invention, a fluid exchange catheter is provided, comprising a proximal end and a distal end, as well as an obligatory lumen having a proximal end and a distal end, wherein a lumen wall of the obligatory lumen forms a distal wall portion at the distal end of the obligatory lumen, the distal wall portion comprising at least one lumen opening for unobstructed fluid exchange, and wherein the distal wall portion exhibits an unblocking function for removing blockage of the catheter for achieving a stable fluid flow through the catheter, the unblocking function being implemented by structural means of the distal end of the catheter and optionally by further providing at least the distal wall portion in at least an area surrounding the at least one lumen opening with expansibility. Further, the invention provides a process for unblocking a fluid exchange catheter, the fluid exchange catheter having a proximal end and a distal end and comprising an obligatory lumen having a proximal end and a distal end, wherein a lumen wall of the obligatory lumen forms a distal wall portion at the distal end of the obligatory lumen, the distal wall portion comprising at least one lumen opening, and wherein the process comprises the step of controlling fluid flow through the obligatory lumen for creating a non-linear motion of the fluid flowing through the at least one opening.Linvention concerne un cathéter déchange de fluide, comprenant une extrémité proximale et une extrémité distale, ainsi quune lumière obligatoire ayant une extrémité proximale et une extrémité distale, une paroi de lumière de la lumière obligatoire formant une partie de paroi distale à lextrémité distale de la lumière obligatoire, la partie de paroi distale comprenant au moins une ouverture de lumière pour un échange libre de fluide, et la partie de paroi distale présentant une fonction de déblocage pour éliminer un blocage du cathéter pour obtenir un écoulement stable de fluide à travers le cathéter,
