A membrane-free perfusion catheter (100) comprising an exchange surface (102) having a filament structure, a delivery unit (801) for delivery of perfusion fluid (112) to a lumen of the filament structure in a manner to allow for an exchange of substances between a medium surrounding the lumen and the perfusion fluid via the filament structure, and a drain unit (804) for draining the medium surrounding the exchange surface and/or for draining the perfusion fluid delivered to the lumen of the filament structure after the exchange of substances between the medium surrounding the lumen and the perfusion fluid via the filament structure.

L'invention porte sur un cathéter de perfusion sans membrane (100) qui  comporte une surface d'échange (102) ayant une structure de filament, une unité de distribution (801) destinée à distribuer un fluide de perfusion (112) à une lumière de la structure de filament de façon à permettre un échange de substances entre un milieu entourant la lumière et le fluide de perfusion par l'intermédiaire de la structure de filament, et une unité de drain (804) destinée à drainer le milieu entourant la surface d'échange et/ou à drainer le fluide de perfusion distribué à la lumière de la structure de filament après l'échange de substances entre le milieu entourant la lumière et le fluide de perfusion par l'intermédiaire de la structure de filament.
