Abstract: A medical device for causing blood flow within a left atrial appendage (LAA) includes a flow energy capture element adapted to capture energy caused by movement within the heart. A transmission element is operably coupled to the flow energy capture element, the transmission element adapted to utilize the captured energy to cause blood flow within the LAA.

Abstract: Implanting a left atrial appendage closure (LAAC) device within a patient's left atrial appendage (LAA) may include advancing an assembly to a position proximate the patient's LAA. The assembly includes an LAAC device releasably secured to an LAAC delivery catheter, and one or more ultrasound transducers disposed relative to the LAAC delivery catheter. Once the LAAC device is deployed, the ultrasound transducers may be rotated relative to the LAAC device to look for leaks between the LAAC device and the LAA. In some cases, the LAAC device may be repositioned relative to the LAA when excessive leaks are found via ultrasound.

Abstract: An implantable medical device such as but not limited to a left atrial appendage closure (LAAC) device includes an expandable frame that is movable between a collapsed configuration for delivery and an expanded configuration for deployment. The expandable frame may include a plurality of articulating members that are biased into the expanded configuration. The expandable frame may include a biasing member. The LAAC device includes a membrane or covering that spans across an end of the expandable frame. In some cases, the LAAC device may be adjustable to better fit a non-circular ostium.

Abstract: A medical implant for occluding a left atrial appendage includes an expandable framework configured to shift between a first configuration and a second configuration, and an occlusive element secured to the expandable framework. The expandable framework includes a plurality of interconnected struts extending from a proximal hub. The plurality of interconnected struts includes a first plurality of struts and a second plurality of struts. In the second configuration, the first plurality of struts each extend radially along a first strut path from the proximal hub to one of a first plurality of strut intersections, and the second plurality of struts each extend radially along a second strut path from the proximal hub to one of a second plurality of strut intersections. In the second configuration, the first plurality of struts forms a depression in the expandable framework and the second plurality of struts extends into the depression.

Abstract: A method of manufacturing a medical implant for occluding a left atrial appendage may include cutting an expandable scaffold in a first configuration, wherein the expandable scaffold includes a plurality of struts having ends joined together at intersection points and a plurality of anchor members extending from the plurality of struts such that each anchor member extends from a medial portion of a strut of the plurality of struts, forming the expandable scaffold into a second configuration, wherein forming the expandable scaffold into the second configuration includes bending each anchor member along its bending axis, the bending axis being oriented parallel to a longitudinal axis of its respective strut of the plurality of struts, and heat setting the expandable scaffold in the second configuration. The method may include securing an occlusive element to the expandable scaffold.

Abstract: A latch locking and release system having a control knob operably coupled with a latch system, and a tubular latch release mechanism. The cross-section of the tubular latch release mechanism is shiftable between a locking configuration and a release configuration. In the locking configuration, the control knob maintains latches in the latch system in an engaged configuration, and is blocked from moving to allow the latches to be disengaged. In the release configuration, the control knob may be moved to allow the latches to be disengaged. The latch release mechanism and control knob may have further features preventing inadvertent actuation of the latch locking and release system to allow the latch system to be disengaged.
