Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device coupled to a delivery catheter includes a fluid flow path that facilitates contrast fluid to pass through the delivery catheter and the medical device to a distal side thereof to provide imaging information as to the position of the medical device positioned in the opening, such as the left atrial appendage. In another embodiment, a medical device is coupled to a delivery catheter, the medical device including flaps adjacent a hub of the medical device that close-off a bore of the hub upon the catheter being detached from the medical device.

Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device includes an anchor portion and an occluder portion. The anchor portion includes frame segments, each anchor frame segment extending between a first end and a second end such that the second end of each anchor frame segment is coupled to an anchor hub. The occluder portion includes a hub that defines an axis. The occluder portion includes multiple occluder frame segments that extend between a proximal end and a distal end such that the proximal end of the occluder frame segments are pivotably coupled to the hub and the distal end of the occluder frame segments are pivotably coupled to the first end of the anchor frame segments.

Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device includes an occluder portion and an anchor portion, the anchor portion hingably coupled to the occluder portion. With this arrangement, the anchor portion actuates and pivots relative to the occluder portion between an anchor deployed position and an anchor non-deployed position while the occluder portion is in an occluder deployed position.

Abstract: Cannula assemblies and related methods are provided. In accordance with one embodiment, a cannula assembly includes a tubular structure coupled with a flange assembly. The flange assembly includes a plurality of wireform loops disposed in a circumferential, woven pattern about an end of the tubular structure. The flange assembly is configured to exhibit a first, collapsed state wherein the plurality of wireform loops extend substantially axially from the tubular structure, and a second, expanded state wherein the plurality of wireform loops extend in a direction having a substantial radial component relative to the tubular structure. In another embodiment, a cannula assembly includes a conformal flange coupled with a tubular structure, wherein the tubular structure extends both distally and proximally of the flange.
