    Abstract: Devices, methods, and systems for closure device for a left atrial appendage and, in particular, to a closure device that includes an anchor element and a disc element that are each individually chosen based on the anatomy of the patient's left atrial appendage and assembled before implantation. In one embodiment, a medical device comprises: an anchor element, the anchor element including a first connection element; and a disc element, the disc element including a second connection element pivotably coupled to the first connection element, the anchor element being sized to be received and retained within a left atrial appendage and the disc element being sized to completely cover an opening of the left atrial appendage.

    Abstract: A transcatheter delivery device including a catheter and at least one stabilizer useful for trasnsseptal procedures. The stabilizer includes a shaft connected to an anchor. The anchor has a delivery position in which the anchor is collapsed against the shaft and a deployed position in which the anchor expands to engage a pulmonary vein or atrial appendage to support the catheter within the septal wall as the catheter moves within a left atrium. Various disclosed delivery devices are also configured to ablate tissue proximate the anchor and/or can be disconnected from the delivery device after the procedure to occlude an atrial appendage. Methods of using the disclosed delivery devices and treating a heart are also disclosed.

    Abstract: Maximum and minimum dimensional characteristics of a conduit are determined by imaging a portion of the conduit into which an expandable medical device is to be implanted at appropriate points in the cardiac cycle (or other suitable cycle, such as the respiratory cycle, or at other suitable times). The dimensional characteristics of the conduits within the portion of interest may be evaluated and compared to the maximum and minimum dimensional characteristics of the medical device to be implanted in the conduit to determine whether the medical device is of an appropriate size for properly fitting in the conduit.
