Devices and methods for crimping medical devices
First Claim
1. A crimping device for use with a medical device that is to be delivered to an implantation site within a patient via a catheter-based delivery device, the medical device comprising a frame that comprises struts that define openings and comprising a soft layer coupled to the frame, the crimping device comprising:
- a force-applying surface configured to compress the entire medical device to a compressed delivery configuration for loading within the catheter-based delivery device by applying a force to an outer surface of the medical device; and
at least one protruding element extending from the force-applying surface and arranged to least partially extend into one of the openings defined by the struts while the medical device is being crimped,wherein the extension of the at least one protruding element at least partially into one of the openings prevents at least a portion of the soft layer of the medical device from protruding between struts of the frame of the medical device while the device is being crimped.

Abstract
A crimping device used with a medical device can include at least one force-applying surface configured to compress the medical device by applying a force to a surface of the medical device. The crimping device also includes at least one protruding element extending from the force-applying surface and arranged to least partially extend into one of the openings defined by frame struts while the medical device is being crimped. The extension of the at least one protruding element at least partially into one of the openings prevents at least a portion of the soft layer of the medical device from protruding between struts of the outer frame of the medical device while the device is being crimped.

12. A crimping system for use with a medical device that is to be delivered to an implantation site within a patient via a catheter-based delivery device, the medical device comprising a frame that comprises struts that define openings and comprising a soft layer coupled to the frame, the crimping system comprising:
-
a crimping device comprising a force-applying surface configured to compress the entire medical device to a compressed delivery configuration for loading within the catheter-based delivery device by applying a force to an outer surface of the medical device; and a support member configured to be placed about a periphery of the medical device between the crimping device and the medical device while the force-applying surface of the crimping device applies a force to the outer surface of the medical device, the support member comprising at least one protruding element extending from an inner surface of the support member and arranged to at least partially extend into one of the openings defined by the struts while the crimping device crimps the medical device, wherein the at least one protruding element is configured to at least partially extend into one of the openings to prevent at least a portion of the soft layer of the medical device from protruding between struts of the frame of the medical device while the device is being crimped. - View Dependent Claims (13)

14. A crimping system for use with a medical device that is to be delivered to an implantation site within a patient via a catheter-based delivery device, the medical device comprising a frame that comprises struts that define openings and comprising a soft layer coupled to the frame, the crimping system comprising:
-
a crimping device comprising a force-applying surface configured to compress the entire medical device to a compressed delivery configuration for loading within the catheter-based delivery device by applying a force to an outer surface of the medical device, and a support member configured to be placed inside the medical device while the force-applying surface of the crimping device applies a force to the outer surface of the medical device, the support member comprising at least one protruding element that extends from an outer surface of the support member and that is arranged to at least partially extend into one of the openings defined by the struts while the crimping device crimps the medical device, wherein the at least one protruding element is configured to at least partially extend into one of the openings to prevent at least a portion of the soft layer of the medical device from protruding between struts of the frame of the medical device while the medical device is being crimped. - View Dependent Claims (15, 16, 17)
