Abstract
Blood stagnation within a left atrial appendage (LAA) may be reduced by creating movement within the LAA. A variety of different actuatable devices, including magnetically actuated devices, may be implanted within the LAA. The actuatable device may be caused to become actuated, thereby causing the motion within the LAA. In some cases, causing the actuatable device to become actuated may include application of a magnetic field. In some cases, causing the actuatable device to become actuated may include subjecting the actuatable device to blood flow within the LAA.
Claims20
A method for reducing blood stagnation within a left atrial appendage (LAA) using a magnetic field to cause motion within the LAA, the method comprising:
- implanting a magnetically actuated device within the LAA;
- causing the magnetically actuated device to become actuated, the magnetically actuated device causing motion within the LAA.
A magnetically actuated device for reducing blood stagnation within a left atrial appendage (LAA), the magnetically actuated device comprising:
- an annular structure comprising:
- an inner segment defining an inner surface of the annular structure, the inner segment having a first magnetic polarity;
- an outer segment defining an outer surface of the annular structure, the outer segment having a second magnetic polarity;
- and
- a magnetically actuatable component secured relative to the annular structure, the magnetically actuatable component having an outer surface having the first magnetic polarity such that magnetic repulsion between the annular structure and the magnetically actuatable component causes movement of the magnetically actuated component.
A magnetically actuated device for reducing blood stagnation within a left atrial appendage (LAA), the magnetically actuated device comprising:
- an elongate cylindrical structure comprising:
- an inner segment defining an inner surface of the elongate cylindrical structure, the inner segment having a first magnetic polarity;
- an outer segment defining an outer surface of the elongate cylindrical structure, the outer segment having a second magnetic polarity;
- and
- a magnetically actuatable component secured relative to the elongate cylindrical structure via one or more elastic tethers, the magnetically actuatable component having an outer surface having the first magnetic polarity such that magnetic repulsion between the elongate cylindrical structure and the magnetically actuatable component causes movement of the magnetically actuated component.
