1. A transcatheter delivery system comprising: a handle; a hollow shaft; a distal tip, a self-expandable heart valve prosthesis;
an actuation mechanism for moving the hollow shaft towards the distal tip or the handle, the hollow shaft configured to slidingly receive the self-expandable valve prosthesis in a compressed state; and
a valve prosthesis crimping tool including a hollow conical element; a detachable transfer tube; and a pulling device,
wherein the hollow conical element is configured to allow the self-expandable valve prosthesis to enter in an expanded state through a base of the hollow conical element, and enter the transfer tube in the compressed state, wherein the valve prosthesis comprises a valve prosthesis anchoring system and the hollow conical element comprising at least one longitudinal groove for accommodating the valve prosthesis anchoring system, wherein the at least one longitudinal groove has an open end at an extremity of the conical element, wherein the longitudinal groove starts at a terminal face of an open end of the hollow conical element, and
wherein the self-expandable valve prosthesis is configured to be pulled by the pulling device when crossing the hollow conical element and entering the detachable transfer tube, the detachable transfer tube configured to be temporarily connected to the hollow conical element.
