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 an actuatable device, the method comprising:
- disposing an actuatable device within the LAA that is adapted to create blood flow within the LAA;
- actuating the actuatable device in order to reduce blood stagnation within the LAA.
The method of claim 16, wherein actuating the actuatable device comprises subjecting the actuatable device to blood flow within the LAA.
A method for reducing blood stagnation within a left atrial appendage (LAA) using an actuatable device, the method comprising:
- disposing an actuatable device within the LAA that is adapted to create blood flow within the LAA;
- monitoring for indications of atrial fibrillation;
- and
- in response to detecting atrial fibrillation, actuating the actuatable device in order to reduce blood stagnation within the LAA.
An actuatable device for reducing blood stagnation within a left atrial appendage (LAA), the actuatable device comprising:
- structure adapted to anchor the actuatable device within the LAA;
- a moveable element that is constrained by the structure but is movable relative to the structure in response to an applied stimuli;
- wherein movement of the moveable element in response to the applied stimuli causes blood flow within the LAA, thereby reducing blood stagnation.
