Abstract
Left atrial occlusion devices and methods of occluding a left atrial appendage. The left atrial occlusion devices can be carried by a flexible elongate member, have an inflatable member, and have a plurality of flexible elongate implant members forming a distally open cage configuration when expanded. The implant members have a flexible format to allow them to conform to the anatomy of the left atrial appendage. The distal ends of the flexible elongate member can optionally be atraumatic.
Claims17
An implantable device adapted for left atrial appendage occlusion, comprising:
- a plurality of elongate members each having a distal end, wherein the distal ends are not directly coupled to anything, and optionally wherein at least one of the distal ends is atraumatic.
A system for positioning a balloon expandable LAA occlusion device, comprising:
- an elongate shaft carrying an expansion balloon, the elongate shaft having an inflation lumen therein in fluid communication with an interior of the balloon;
- an implantable LAA occlusion device adapted to be fit over at least a portion of the balloon in a non-expanded configuration, the implantable device including a plurality of balloon expandable elongate members, the elongate members having open ends and proximal ends attached to a barrier.
A method of occluding a left atrial appendage (“LAA), comprising:
- delivering a system for deploying a left atrial appendage occlusion device to the left atrial appendage, the system comprising:
- a delivery catheter, the delivery catheter comprising:
- a balloon attached to a distal end of the delivery catheter;
- the balloon having a preformed shape when inflated;
- wherein the balloon is constructed of a compliant material;
- a left atrial appendage occlusion device comprising:
- an endoskeleton, the endoskeleton constructed of a flexible material and comprising barbs;
- a barrier layer;
- inflating the balloon from a deflated form to the preformed shape;
- expanding the endoskeleton with the inflated balloon;
- plastically deforming the endoskeleton from a first, compressed form to a second, expanded form;
- deflating the balloon;
- removing the balloon and the delivery catheter;
- wherein the endoskeleton is configured to remain in the second, expanded form.
