摘要:
The present invention relates to a deployment system (10) for deploying an expandable cardiac valve prosthesis. The deployment system comprises a first tube (11) being designed to carry an expandable cardiac valve prosthesis; further, a tip (13), being firmly connected to the first tube at a distal end of the first tube, wherein the tip is designed such, that it detachably accommodates and holds a proximal end (21) of a cardiac valve prosthesis (20); a sheath (15) designed to be disposed over and holding the prosthesis (20) in a compressed state, and a first actuating mechanism (16) being linked to the sheath (15) and being slidable in a proximal direction for stepwise retracting the sheath (15). The deployment system (10) further comprises a biasing element being linked to the tip (13), and a blocking mechanism (24), wherein the blocking mechanism is being designed such, that a movement of the first actuating mechanism (16) in the proximal direction relative to the tip (13) is limitable to a maximum path of travel by the blocking mechanism (24).
