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: 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: The disclosure pertains to a delivery system for delivering a left atrial appendage treatment device or the like to a left atrium and methods of use therefor. The delivery system includes a control housing containing a differential displacement mechanism adapted to manipulate the distal end of an elongate steerable catheter through differential displacement of control elements attached proximate the distal end of the elongate steerable catheter. The elongate steerable catheter includes a stiff proximal region, a somewhat more flexible curved intermediate region and a more flexible distal region adapted to be displaced from the plane of the second curved region.

Abstract: An occlusive implant system may include an access device including a handle and an access sheath extending distally therefrom. The access device includes a working lumen extending longitudinally therethrough. A proximal portion of the working lumen defines a garage section and a distal portion of the working lumen extends distally of the garage section. The occlusive implant system may include an occlusive implant device including a delivery sheath configured to be received within the garage section, the delivery sheath having a delivery lumen, a core wire disposed therein, and an occlusive implant releasably attached to the core wire. The garage section has a first inner diameter and the distal portion of the working lumen has a second inner diameter less than the first inner diameter. The delivery sheath has an outer diameter less than the first inner diameter and greater than the second inner diameter.
