Patent Images
1. A device for crimping an expandable prosthetic heart valve, the device comprising:
- a first annular body and a second annular body arranged for relative rotation generally about an axis; and
an array of linear crimping elements having first ends coupled to the first annular body and second ends coupled to the second annular body, wherein the array of linear crimping elements defines an orifice;
wherein the first body and the second body are configured to rotate about the axis between a first position, wherein the crimping elements define the orifice with a first diameter and a second position, wherein the crimping elements define the orifice with a second diameter;
wherein the crimping elements include a plurality of flexible elements extending in a generally serpentine pattern between the first and second annular bodies, wherein the pattern includes portions of the flexible elements extending between the first and the second annular bodies to define the crimping elements.

Abstract
A device for crimping an implantable device or a part thereof between a radially expanded condition and a radially contracted condition, includes first and second annular bodies arranged about a common axis, and a ring-like array of linear crimping elements having respective opposite ends linked to the first and second annular bodies, respectively. These annular bodies are relatively rotatable around the common axis between a first position, wherein the annular array of crimping elements define a wider orifice for receiving a device to be crimped, and a second position, wherein the annular array of crimping elements define a narrower orifice.

9. A device for crimping an expandable prosthetic heart valve, the device comprising:
-
a first annular body, a second annular body, and a third annular body each arranged generally about an axis, the first annular body interposed between the second annular body and the third annular body, the second annular body including a peripheral rim extending around the first annular body, such that the first and the second annular bodies are generally centered about the axis; wherein the first annular body is arranged for relative rotation with respect to each of the second annular body and the third annular body; an array of linear crimping elements having first ends coupled to the first annular body and second ends coupled to the second annular body, wherein the array of linear crimping elements defines an orifice; and a second array of linear crimping elements provided between the first annular body and the third annular body; wherein the first body and the second body are configured to rotate about the axis between a first position, wherein the crimping elements define the orifice with a first diameter and a second position, wherein the crimping elements define the orifice with a second diameter; wherein the crimping elements include a plurality of flexible elements extending in a generally serpentine pattern between the first and second annular bodies, wherein the pattern includes portions of the flexible elements extending between the first and the second annular bodies to define the crimping elements. - View Dependent Claims (10)
