Atrial appendage occlusion and arrhythmia treatment
Atrial appendage occlusion devices and cardiac monitoring positioned within the left atrial appendage and/or left atrium. In some embodiments the devices include an anchoring portion adapted to anchor the device in place adjacent the left atrial appendage, the anchoring portion comprising distal deformable anchoring portion adapted to be deployed in the left atrial appendage and a proximal deformable anchoring portion being adapted to be deployed in the left atrium, a barrier element secured to the anchoring portion and adapted to cover the left atrial appendage when implanted, and adapted to prevent blood clots from passing through the barrier element, and a cardiac monitoring element secured to at least one of the anchoring portions, the monitoring element including one or more sensors within in the left atrial appendage and/or left atrium and adapted to monitor left atrial cardiac data.
1. A left atrial appendage (LAA) occlusion implant, comprising:
a tubular element with a proximal hub on a proximal end and a distal hub on a distal end;
a plurality of proximal leaflet shaped anchors coupled to the proximal hub being adapted to extend proximally and engage the atrial tissue around the LAA ostium;
a plurality of distal leaflet shaped anchors coupled to the proximal hub being adapted to extend distally and engage the LAA tissue; and
a secondary anchor having a plurality of secondary leaflet shaped anchors coupled to the distal hub being adapted to expand with an outwardly directed force against the LAA tissue to secure the implant in place.
2. The implant of claim 1 , wherein the plurality of proximal and distal leaflet shaped anchors include proximal and distal leaflet shaped frame elements made from shape memory material secured to the proximal hub.
3. The implant of claim 2 , wherein the proximal leaflet shaped anchors include barriers covering the proximal leaflet shaped frame elements, the barriers being adapted to prevent blood clots from passing through the barriers.
4. The implant of claim 2 , wherein the plurality of secondary leaflet shaped anchors include secondary leaflet shaped frame elements made from shape memory material secured to the distal hub.
5. The implant of claim 1 , wherein the proximal and distal leaflet shaped anchors are adapted to be collapsed down into delivery configurations such that they can be delivered endoluminally.
6. The implant of claim 5 , wherein the proximal and distal leaflet shaped anchors are configured to overlap one another into a staggered orientation as they collapse.
7. The implant of claim 1 , wherein the plurality of proximal leaflet shaped anchors are made in two or more sizes, and the plurality of distal leaflet shaped anchors are made in two or more sizes.
8. The implant of claim 1 , wherein the secondary anchor includes cardiac monitoring and/or pacing capabilities in contact with the LAA tissue.
9. The implant of claim 1 , wherein the secondary anchor includes sensing and/or stimulating electrodes in contact with the LAA tissue.
10. A left atrial appendage (LAA) occlusion implant, comprising:
a tubular element with a proximal hub and a distal hub;
a plurality of proximal leaflet shaped anchors having proximal leaflet shaped frame elements made from shape memory material secured to the proximal hub being adapted to extend proximally and engage the atrial tissue around the LAA ostium;
a plurality of distal leaflet shaped anchors having distal leaflet shaped frame elements made from shape memory material secured to the distal hub being adapted to extend distally and engage the LAA tissue; and
a secondary anchor having a plurality of secondary leaflet shaped anchors having secondary leaflet shaped frame elements made from shape memory material secured to the distal hub being adapted to expand with an outwardly directed force against the LAA tissue to secure the implant in place.
11. The implant of claim 10 , wherein the proximal leaflet shaped anchors include barriers covering the proximal leaflet shaped frame elements, the barriers being adapted to prevent blood clots from passing through the barriers.
12. The implant of claim 10 , wherein the proximal and distal leaflet shaped anchors are adapted to be collapsed down into delivery configurations such that they can be delivered endoluminally.
13. The implant of claim 12 , wherein the proximal and distal leaflet shaped anchors are configured to overlap one another into a staggered orientation as they collapse.
14. The implant of claim 10 , wherein the secondary anchor includes cardiac monitoring and/or pacing capabilities positioned in contact with the LAA tissue.
15. The implant of claim 10 , wherein the secondary anchor includes sensing and/or stimulating electrodes positioned in contact with the LAA tissue.
16. A left atrial appendage (LAA) occlusion implant, comprising:
a tubular element with a proximal hub and a distal hub;
a plurality of proximal leaflet shaped anchors having proximal leaflet shaped frame elements made from shape memory material secured to the proximal hub being adapted to extend proximally and engage the atrial tissue around the LAA ostium;
a plurality of distal leaflet shaped anchors having distal leaflet shaped frame elements made from shape memory material secured to the distal hub being adapted to extend distally and engage the LAA tissue; and
a secondary anchor having a secondary expandable bulb anchor adapted to expand with an outwardly directed force against the LAA tissue to secure the implant in place.
