摘要：
Placement apparatus (10) for implanting a compressible and expandable prosthetic heart valve (12) in a radial direction in a native heart valve, the apparatus comprising: an elongated rod (26) comprising a proximal end portion (24) and a distal end portion； an inflatable balloon (28) mounted on the distal end portion of the rod (26)； and a valve mounting element (124； 140) attached at the distal end portion of the stem (26) inside the balloon (28) and configured to facilitate frictional engagement between the prosthetic heart valve (12) and the balloon ( 18) when the prosthetic heart valve (12) is mounted in a compressed state in radial direction on the balloon (28) and surrounding the mounting element (124； 140), the mounting element (124； 140) comprising at least one fluid channel extending longitudinally and through which a swelling fluid can flow into the balloon (28), the fluid channel (s) having a first and a second opening next to a first and a second end of the heart valve prosthetic (12), respectively, with the prosthetic heart valve (12) mounted on the balloon (28) in a folded state surrounding the mounting element (124； 140), characterized in that the at least one fluid channel allows the fluid swollen in the balloon (28) a first zone of the balloon (28) flows proximally with respect to the first end of the prosthetic valve (12), inwards through the first opening, through the fluid channel, outwards through the second opening and into a second zone of the balloon (28) distally with respect to the second end of the prosthetic valve (12).Aparato de colocación (10) para implantar una válvula cardíaca protésica (12) compresible y expandible en dirección radial en una válvula cardíaca nativa del corazón, comprendiendo el aparato: un vástago (26) alargado que comprende una parte de extremo proximal (24) y una parte de extremo distal； un balón hinchable (28) montado sobre la parte de extremo distal del vástago (26)； y un elemento de montaje de válvula (124； 140)
