Abstract: Systems, devices and methods for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame having anchors and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. A loader includes a conical portion with guides and a reservoir for submerging the foam implant prior to loading and delivery.

Abstract: Devices and methods are described for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body carried by the frame. The device may have a thromboresistant cover at a proximal end and a thromboresistant coating on the foam body. The frame may have recapture struts inclining radially outwardly in the distal direction from a central hub. The frame may have axially extending side wall struts, with adjacent pairs of side wall struts joined at one or more apexes. Anchors extend from the frame to engage tissue. The anchors can also be reversible to allow retraction of the anchors and repositioning or retrieval of the device.

The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. A delivery and tether retraction system includes a handle for controlling a pusher and tether. The pusher may be moved a distance away from the implant without changing the orientation of the implant, while the tether is still attached to the implant. Severing the tether and proximally retracting a control on the hand piece by a distance causes the severed end to advance distally by at least about twice that distance. A loader includes a conical portion with guides and a reservoir for submerging the foam prior to loading and delivery.
