    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.

    Abstract: A catheter comprising a shaft and a distal end portion extending distally from the distal end of the shaft and defining a longitudinal axis. The distal end portion comprises a proximal segment, a distal segment located distally of the proximal segment, the distal segment being displaceable relative to the proximal segment, and a force sensing mechanism that includes a proximal housing fixed within the proximal segment, a piezoelectric sensor mounted to the proximal housing and having a first portion fixedly secured to the proximal housing, and a second portion that is not fixedly secured to the proximal housing, and a distal housing fixed within the distal segment and including a projection that contacts the second portion of the piezoelectric sensor and is configured to apply an axial force to the second portion of the piezoelectric sensor upon application of an external force to the distal segment.
