    Abstract: Occlusion device for an atrial appendage, the device having proximal and distal ends and a central axis and comprising a cage-like structure formed of struts, the struts having proximal strut ends and distal strut ends, wherein at the proximal end of the device the struts extend towards the central axis and are connected to each other at their proximal strut ends, and wherein at least some of the struts are connected to each other at their distal strut ends within the cage-like structure so that the struts form an atraumatic distal end of the device.

    Abstract: A bi-directional steerable catheter may include a handle and an elongate sheath extending distally from the handle. The handle includes an axial translation mechanism. A first steering wire extends through the elongate sheath from the handle to a distal pull ring. A second steering wire extends through the elongate sheath from the handle to the distal pull ring, the second steering wire being disposed on an opposite side of the elongate sheath from the first steering wire relative to a central longitudinal axis. The first steering wire is configured to engage with the axial translation mechanism to bend a distal portion of the elongate sheath in a first direction. The second steering wire is configured to engage with the axial translation mechanism to bend the distal portion in a second direction opposite the first direction. A tensioning member couples a proximal end of the first steering wire to the handle.

    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 drug delivery device that uses centrifugal force to deliver a drug to a body lumen wall. The drug delivery device comprises an impeller that includes an impeller shaft; an impeller head at the distal end of the impeller shaft; a drug lumen; an impeller housing; and a housing shaft attached to the impeller housing. In use, the drug is advanced along the drug lumen to the impeller head; at least the impeller head is rotated so that when drug exits the drug lumen, the centrifugal force of the rotating impeller causes the drug to move radially outward from the drug delivery device, towards and into the body lumen wall.

    Abstract: A medical device for left atrial appendage closure includes a support frame with a proximal collar and a distal collar, where the support frame is actuatable from a first constrained configuration to a second radially expanded configuration. A membrane is disposed on at least a portion of the support frame, and an engagement element is coupled to the distal end region of the support frame. The engagement element extends distally from the support frame and is configured to engage an inner surface of the left atrial appendage and prevent the support frame from sliding along the inner surface of the left atrial appendage during implantation.
