The invention relates to an expandable conduit-guide (1) providing a leak- tight conduit through a skin (3) between an inside of a corpus (2) and an outside of the corpus (2). Said conduit-guide (1) includes a body (100) encompassing a lumen (110) extending essentially axially along a center-line (120), and has a distal-end (130) to be positioned outside of the corpus (2), and a proximal- end (140) to be positioned inside of the corpus (2), so that a medical device (4) can be placed in and passed through the lumen (110) between the distal-end (130) and the proximal-end (140). The body (100) of the conduit-guide (1) is constructed from a braided-wire (150) so that the conduit-guide (1) is capable of actively expanding from a closed diameter (D1) to an opened diameter (D2) with the placement of the medical device (4) positioned within the lumen(110) and passively collapsing from the opened diameter (D2) to the closed diameter (D1) upon withdrawal of the medical device (4) under a spring load of the braided-wire (150). The invention is also related to a catheter-sheath (8) and a catheter-sheath-assembly (800) as well as to a method for applying and positioning an expandable conduit-guide (1), catheter-sheath (8) and a catheter-sheath-assembly (800) in accordance with the present invention.
