摘要： 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.

摘要： 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.

摘要： 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.
