    Abstract: An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion, a middle portion, and a distal portion, wherein: the proximal portion includes a first hub that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams extending from the first hub to a distal portion, wherein each of the plurality of beams is connected to an adjacent beam by a first circumferentially extending column of strut pairs; and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening.

    Abstract: A left atrial appendage closure implant may include a support frame including a first bend extending from a proximal collar to a second bend, a first segment extending from the second bend to a third bend, a second segment extending from the third bend to a fourth bend, and a third segment extending from the fourth bend to a distal collar, wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid-deployment position to a fourth unconstrained position. An implant may include a self-expanding support frame having a circumference and a central longitudinal axis, a membrane disposed over at least a portion of the support frame, and a plurality of anchors arranged into a first row and a second row such that the first row and the second row form a staggered pattern about the circumference of the support frame.

    Abstract: A left atrial appendage closure implant (200) may include a support frame (210) including a first bend (240) extending from a proximal collar (212) to a second bend (242), a first segment (270) extending from the second bend (242) to a third bend (244), a second segment (272) extending from the third bend (244) to a fourth bend (246), and a third segment (274) extending from the fourth bend (246) to a distal collar (214), wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid- deployment position to a fourth unconstrained position. An implant may include a self-expanding support frame having a circumference and a central longitudinal axis, a membrane disposed over at least a portion of the support frame, and a plurality of anchors arranged into a first row and a second row such that the first row and the second row form a staggered pattern about the circumference of the support frame
