The present invention provides an apparatus (1) for processing a medical stent, comprising: a holding device (2) for holding a stent (S), and a processing device (3) for processing the stent held by the holding device (2). The holding device (2) comprises a first chamber (5) for a fluid medium adapted to exert pressure around the stent. The first chamber (5) for the fluid medium at least partially, and preferably fully, surrounds or encompasses the stent in the holding device (2). The holding device (2) desirably comprises a housing (4) which substantially encloses the first chamber (5) for the fluid medium, wherein the holding device (2) further includes a second chamber (8) for receiving the stent, and wherein the first chamber (5) for the fluid medium is separated from the second chamber (8) by at least one moveable and/or flexible wall (7). The invention also provides a method of processing a medical stent, comprising the steps of: holding a stent (S) with a holding device (2), and processing the stent with a processing device (3) while holding the stent with the holding device. The step of holding the stent comprises pressurizing a first chamber (5) for a fluid medium to exert pressure around the stent. The invention also provides a stent produced or manufactured according to this method.La présente invention se rapporte à un appareil (1) servant à traiter une endoprothèse médicale, comprenant : un dispositif de maintien (2) servant à maintenir une endoprothèse (S), et un dispositif de traitement (3) servant à traiter l’endoprothèse maintenue par le dispositif de maintien (2). Le dispositif de maintien (2) comprend une première chambre (5) destinée à un milieu fluide conçu pour exercer une pression autour de l’endoprothèse. La première chambre (5) destine au milieu fluide entoure ou englobe au moins partiellement, et de préférence totalement, l’endoprothèse dans le dispositif de maintien (2). Le dispositif de maintien (2) comprend de préférence un logement (4)
