CRIMPING DEVICE AND METHOD FOR MOUNTING A VASCULAR STENT
First Claim
1. A crimping device for mounting a vascular stent, or a heart valve prosthesis introduced in the vascular stent, on an insertion catheter, comprising:
- a forming tool having a rotationally symmetrical forming cavity, which at one end comprises a stent receiving section, at the opposing end a stent outfeed section and in between the stent receiving section and the stent outfeed section, a tapering section, anda pushing tool, which comprises a retaining and handling section and a stent forming section, wherein the stent forming section is designed to penetrate the forming cavity of the forming tool from an open end of the stent receiving section and to seize and push back the vascular stent introduced in the forming tool through the tapering section.

11. A method for mounting a vascular stent, or a heart valve prosthesis introduced in the vascular stent, on an insertion catheter, comprising:
-
providing an expanded vascular stent or a heart valve prosthesis comprising an expanded vascular stent; providing an insertion catheter comprising an inner tube having a catheter tip and an outer tube that is displaced with respect to the inner tube; providing a forming tool having a rotationally symmetrical forming cavity, which at one end comprises a stent receiving section, at an opposing end comprises an outer tube receiving section and in between the stent receiving section and the outer tube receiving section, a tapering section; providing a pushing tool, which comprises a retaining and handling section and a stent forming section, wherein the stent forming section is designed to penetrate the forming cavity of the forming tool from an open end of the stent receiving section and to seize and push back the vascular stent introduced in the forming tool through the tapering section; introducing the vascular stent or the heart valve prosthesis in the stent receiving section of the forming tool; introducing a distal end of the insertion catheter in the forming tool, wherein a distal end of the outer tube, in a retracted state, is fixed in the outer tube receiving section of the forming tool; and inserting the stent forming section of the pushing tool into an open end of the stent receiving section of the forming tool and pushing back the vascular stent or the heart valve prosthesis through the forming cavity while reducing a diameter of the vascular stent or the heart valve prosthesis, and while simultaneously pushing the vascular stent or the heart valve prosthesis between the outer tube and inner tube of the insertion catheter.

12. A crimping device for mounting an implant on an insertion catheter, the device comprising:
-
a first half shell with a first side; a second half shell that cooperates with the first half shell, the second half shell having a first side; at least one hinge arranged about the first half shell first side and the second half shell first side to thereby pivotably connect the first and second half shells wherein they pivotably move about the at least one hinge and have a closed position wherein they abut one another; and
,a forming cavity defined between the first half shell and the second half shell when they are in the closed position, the forming cavity defining an outer tube receiving section at an open first end, a funnel shaped tapered section adjacent to the tube receiving section, an annular shoulder separating the outer tube receiving section from the adjacent funnel shaped tapered section, and a stent receiving section adjacent to the at least one tapered section and open at a second cavity end. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
