Appl. No.:

17/210636

Inventors:

- Luxembourg, LU
Gopikrishnan SOUNDARARAJAN - Irvine CA, US

International Classification:

A61F 2/24

Abstract:

A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments.

Assignee:

MEDTRONIC, INC. - Minneapolis MN

International Classification:

B21D 51/16

US Classification:

29428, 29 33 K

Abstract:

A device for crimping an expandable medical device and loading the expandable medical device into a delivery system includes an actuator, a compression assembly, and a pusher. The compression assembly is disposed in a compression chamber of the actuator and includes a plurality of compression elements coupled to each other to form a central cavity. The compression elements are coupled to the actuator such that rotation of the actuator causes the compression elements to rotate such that the central cavity radially compresses from an expanded configuration to a compressed configuration. The pusher includes a pusher rod and is configured to translate relative to the actuator towards the compression chamber when the cavity is in the compressed configuration such that the pusher rod may enter the cavity and push the medical device out of the cavity into delivery system.

MEDTRONIC, INC. - Minneapolis MN

International Classification:

A61M 25/00

US Classification:

29428, 29700

Abstract:

A device for crimping an collapsible device and loading the collapsible device into a delivery system, includes a crimping tool configured to radially crimp at least a portion of the collapsible device, a loading tool configured to load at least a portion of the collapsible device into a delivery system, and a housing that houses at least one of the crimping tool and loading tool, wherein the device is configured to crimp and load the collapsible device without requiring manual repositioning of the collapsible device. Methods of crimping an collapsible device and loading the collapsible device into a delivery system are also disclosed.
