Abstract: An implant includes a frame comprising a tubular body formed by a plurality of interconnected struts that are manufactured to reduce stresses and strains resulting from component interaction during chronic use. At least a portion of a longitudinal corner of one or more struts of the frame may be chamfered, rounded, or otherwise modified to distribute stresses experienced at the strut corner throughout the strut body. Chamfering and/or rounding corners along at least a portion of a strut of the frame may reduce stresses on the frame caused by interactions between the frame and other components of the implant. The implant may be manufactured by cutting (e.g., laser cutting) a plurality of struts from a tubular metal alloy, polymer, or the like forming the tubular body, and softening at least a portion of an edge of the strut by cutting, grinding, and/or micro-blasting the edges of the corner.

Abstract: An example system for detecting leakage around an implant is disclosed. The example system for detecting leakage around an occlusive implant disposed in the left atrial appendage includes an elongate shaft having a port disposed at a distal end region thereof and a first sensor disposed adjacent the elongate shaft. The elongate shaft is configured to be positioned adjacent the occlusive implant such that the first sensor is positioned on a first side of the occlusive implant and the port is positioned on a second side of the occlusive implant. Further, the first sensor is configured to measure a first parameter and the first parameter is utilized to determine a fluid leak between the occlusive implant and a tissue wall defining the left atrial appendage.

Abstract: A delivery system for delivering, adjusting, and/or recapturing a stent-valve includes an inner shaft and an expandable stent-valve coupled to the inner shaft. The stent-valve has an upper portion, a lower portion, and a valve. The delivery system also includes a distal sheath disposed over at least the lower portion, a proximal sheath disposed over at least the upper portion, and at least one cinching member coupled to the stent-valve and extending through one of the inner shaft, the distal sheath, or the proximal sheath. The upper and lower portions of the stent-valve are configured to move to an expanded configuration when the proximal and distal sheaths are withdrawn, respectively. After at least a portion of the stent-valve has been moved to the expanded configuration, the at least one cinching member is configured to at least partially radially compress at least a portion of the stent-valve.

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.
