Left Atrial Appendage Occluder

摘要

An occluder for a left atrial appendage is disclosed comprising a proximal portion comprising a braiding of at least one thread being radially self-expandable in a radial direction, to an expanded state, substantially perpendicular to a surface of inner walls of the left atrial appendage, whereby said braiding is engageable with said inner walls of a proximal end of said left atrial appendage, whereby in said expanded state, said proximal portion has a defined stiffness and resilience to be deformable by, and conformable to, said inner walls, whereby said braiding is configured to form a sealing connection, upon expansion in said radial direction, with said inner walls along a sealing portion of said braiding extending in a longitudinal direction of said occluder, substantially perpendicular to said radial direction. Said occluder comprising further a distal anchoring portion comprising an anchoring wire being radially expandable from a reduced diameter shape to an expanded diameter shape, said anchoring portion having a higher defined stiffness than said proximal portion, and a flexing element connecting said anchoring portion and said proximal portion

1. An occluder for a left atrial appendage comprising:
a proximal portion comprising a braiding of at least one thread being radially self-expandable in a radial direction, to an expanded state, substantially perpendicular to a surface of inner walls of said left atrial appendage, whereby said braiding is engageable with said inner walls of a proximal end of said left atrial appendage, whereby in said expanded state, said proximal portion has a defined stiffness and resilience to be deformable by, and conformable to, said inner walls, whereby said braiding is configured to form a sealing connection, upon expansion in said radial direction, with said inner walls along a sealing portion of said braiding extending in a longitudinal direction of said occluder, substantially perpendicular to said radial direction, a distal anchoring portion comprising an anchoring wire being radially expandable from a reduced diameter shape to an expanded diameter shape, said anchoring portion having a higher defined stiffness than said proximal portion, a flexing element connecting said anchoring portion and said proximal portion and allowing movement between said anchoring portion and said proximal portion from a relaxed configuration to a deployed configuration.
