Abstract
Various aspects of the present disclosure are directed toward apparatuses, methods, and systems as relating to occlusion. In certain instances, the apparatuses, methods, and systems may include a device for placement in vessels, appendages, and openings in a body. The device may include a unitary frame having a face portion that includes a center frame portion a plurality of elongate members.
Claims20
A device for placement in vessels, appendages, and openings in a body, the device comprising:
- a unitary self-expanding frame having a proximal end, a distal end, and a longitudinal axis, the unitary self-expanding frame including:
- a face portion having a pre-loaded flat configuration and (i) a center frame portion arranged at the proximal end and (ii) a plurality of elongate members extending from the center frame portion, and
- a body portion;
- and
- a membrane attached to the unitary self-expanding frame;
- wherein the plurality of elongate members are configured to bend or flex substantially in a plane orthogonal to the longitudinal axis and mitigate longitudinal movement of the face portion in response to a compressive force applied to the body portion of the unitary self-expanding frame.
A device for placement in vessels, appendages, and openings in a body having an elongated configuration and a deployed configuration, the device comprising:
- a nitinol cut-tube frame having a proximal end and a distal end, the nitinol cut-tube frame including:
- a face portion having
- a center frame portion arranged at the proximal end and including a plurality of arcs arranged around a circumference of the center frame portion, and
- a plurality of elongate members extending from the center frame portion, and
- a body portion;
- and
- a membrane attached to the nitinol cut-tube frame;
- wherein the center frame portion and the plurality of elongate members form a substantially uniform surface, wherein the plurality of elongate members are configured to bend or flex in a plane that is substantially orthogonal to a longitudinal axis of the nitinol cut-tube frame to mitigate longitudinal movement of the face portion in response to a compressive force applied to the body portion of the nitinol cut-tube frame, and the center frame portion is configured to provide an attachment point for a delivery system for the device.
A method of reducing thrombus formation in treatment of left atrial appendage of a patient, the method comprising:
- positioning a transcatheter assembly through an ostium of the left atrial appendage;
- deploying a device from the transcatheter assembly, the device comprising:
- a unitary self-expanding frame having a proximal end, a distal end, and a longitudinal axis, the unitary self-expanding frame including a face portion having a center frame portion arranged at the proximal end and a plurality of elongate members extending from the center frame portion, a body portion arranged substantially orthogonal to the face portion, and a membrane attached to the unitary self-expanding frame, wherein the face portion and the membrane define an occlusive face of the device;
- and
- absorbing one or more forces from the left atrial appendage with thereby flexing the plurality of elongate members in a plane orthogonal to the longitudinal axis to mitigate longitudinal movement of the face portion in response thereto.
