Abstract

A system for mounting a heart valve prosthesis on a catheter shaft, the system having at least two components, each component at least partially enclosing a rotation-symmetrical space tapering along an axis of symmetry, the at least two components being designed in such a way that a relative movement of the at least two components along a longitudinal axis of a heart valve prosthesis to be mounted can take place toward one another and into one another in such a way that a space enclosed jointly by the at least two components is decreased. At least one component has a mandrel, which is oriented centrally in the space enclosed by the component and is located on the axis of symmetry of the rotation-symmetrical space.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A system for mounting a heart valve prosthesis on a catheter shaft, the system comprising at least two components, each component at least partially enclosing a rotation-symmetrical space tapering along an axis of symmetry,
 wherein at least one of the components, at a tapered end of the enclosed rotation-symmetrical space, comprises an opening that is suitable for a catheter shaft to be passed through,   wherein the at least two components are designed in such a way that a relative movement of the at least two components along a longitudinal axis of a heart valve prosthesis to be mounted can take place toward one another and into one another in such a way that a space enclosed jointly by the at least two components is decreased, and   wherein at least one component comprises a mandrel, which is oriented centrally in the space enclosed by the component and is located on the axis of symmetry of the rotation-symmetrical space.   
     
     
         2 . The system according to  claim 1 , wherein the rotation-symmetrical space tapering along the axis of symmetry in one direction is a cone. 
     
     
         3 . The system according to  claim 2 , wherein at least one or two components enclose a space formed by a cone and a cylinder. 
     
     
         4 . The system according to  claim 1 , wherein each of the at least two components has recesses in which the respective other component(s) can engage. 
     
     
         5 . The system according to  claim 1 , wherein at least one component comprises a stop for the catheter shaft. 
     
     
         6 . The system according to  claim 1 , wherein at least one component comprises a seat for the heart valve prosthesis. 
     
     
         7 . The system according to  claim 1 , wherein two of the at least two components are tapered in opposite directions. 
     
     
         8 . The system according to  claim 1 , wherein one of the at least two components comprises a plurality of recesses and another of the at least two components comprises longitudinally extending finger shapings that fit longitudinally through the recesses during the movement. 
     
     
         9 . A system for mounting a heart valve prosthesis on a catheter shaft, the system comprising two components, each of the two components at least partially enclosing a shared rotation-symmetrical space tapering along an axis of symmetry and sized for longitudinally positioning a heart valve prosthesis within the space, wherein:
 the two components are movable longitudinally toward and into one another, thereby decreasing the space,   at least one of the components comprises a tapered end with an opening sized for a catheter shaft to be passed through the opening, and   at least one of the components comprises a mandrel oriented centrally in the space at least partially enclosed by the component and located on the axis of symmetry of the rotation-symmetrical space.   
     
     
         10 . The system according to  claim 9 , wherein the two components are tapered in opposite directions. 
     
     
         11 . The system according to  claim 9 , wherein one component comprises a plurality of recesses and another component comprises longitudinally extending finger shapings that fit longitudinally through the recesses during the movement.
