  • Patent number: 9414914
    Abstract: Catheter assemblies including a handle assembly located on the proximal end of the catheter assembly and a distal tip assembly located on the distal end of the catheter assembly. A crimping funnel is slidably positioned along the catheter. The crimping funnel includes a distal end having a first diameter and a proximal end having a second diameter smaller than the first diameter. An axial split is formed in the proximal end. A first collar is provided encompassing a portion of the proximal end. The first collar is configured to hold the axial split in the proximal end together when the first collar is at a first axial location along the proximal end, and to allow the axial split in the proximal end to open when the first collar is at a second axial location along the proximal end, such that the crimping funnel can be removed from the catheter assembly. Various methods of retaining a prosthetic valve on the catheter assembly during the crimping process are described.

  • Patent number: 9192469
    Abstract: A method for loading a prosthesis onto a delivery system includes passing a distal end of a delivery system through a first open end and a second open end of a reducing member. The method includes seating the prosthesis in a piston member of a cap by contacting a first end of the prosthesis with a first surface of the piston member and by contacting a portion of a side of the prosthesis with at least one side wall extending from the periphery of the first surface. Additionally, the method includes inserting the distal end of the delivery system into a center of the prosthesis and an opening defined by the piston member. And the method includes advancing the cap towards a reducing member such that a portion of the prosthesis seated in the piston member advances along an inner surface of the conical wall of the reducing member.

  • Patent number: 8562663
    Abstract: In an embodiment, a device for loading a prosthesis onto a delivery system comprises a cap and a reducing member. The cap has a piston member that seats a prosthesis. The piston member has at least one side wall configured to contact a portion of the side of the prosthesis seated therein. The reducing member has a conical wall, a first open end, and a second open end. The first open end is configured to receive the piston member. The reducing member reduces an external dimension of at least a portion of the prosthesis seated in the piston member as the prosthesis is moved along an inner surface of the conical wall.
