1. An assembly comprising:
- a delivery catheter comprising a balloon; and
an implantable prosthetic heart valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the prosthetic heart valve comprising;
a radially expandable annular frame having an inflow end portion defining an inflow end of the frame that is configured to receive antegrade blood flow into the prosthetic heart valve when implanted within a patient'"'"'s body in the expanded configuration, and the frame also having an outflow end portion defining an outflow end of the frame opposite the inflow end of the frame;
wherein the frame comprises at least first and second circumferentially extending rows of angled struts arranged end-to-end in a zig-zag pattern and a plurality of axially extending struts interconnecting the first and second rows of angled struts; and
wherein each of the axially extending struts joins to a U-shaped crown structure joining adjacent ends of struts of the first row of angled struts and joins to a U-shaped crown structure joining adjacent ends of struts of the second row of angled struts, wherein the first and second rows of angled struts and axially extending struts form a circumferentially extending row of six-sided cells of the frame;
wherein the prosthetic valve can be radially crimped to the collapsed configuration around the balloon for delivery into a patient'"'"'s body and radially expanded to the expanded configuration with the balloon inside the patient'"'"'s body.

Abstract
A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.

13. An assembly comprising:
-
a delivery catheter comprising a balloon; and an implantable prosthetic heart valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the prosthetic heart valve comprising; a radially collapsible and expandable annular frame, the frame having three commissure attachment portions and at least three rows of circumferentially extending rows of angled struts including a first row of angled struts defining an inflow end of the frame, a second row of angled struts, and a third row of angled struts defining an outflow end of the frame, the second row of struts being positioned axially between the first and third rows of angled struts along a length of the frame, the frame further comprising a plurality of axially extending struts interconnecting the first and second rows of angled struts; a leaflet structure comprising three leaflets defining three commissures, each commissure being attached to one of the commissure attachment portions; and wherein each of the axially extending struts joins to a U-shaped crown structure joining adjacent ends of struts of the first row of angled struts and joins to a U-shaped crown structure joining adjacent ends of struts of the second row of angled struts; wherein the prosthetic valve can be radially crimped to the collapsed configuration around the balloon for delivery into a patient'"'"'s body and radially expanded to the expanded configuration with the balloon inside the patient'"'"'s body. - View Dependent Claims (14, 15, 16, 17)
