1. A left atrial appendage occlusion device, comprising:
an expandable foam body having a proximal end and a sidewall extending distally from the proximal end;
an expandable frame carrying the foam body and configured to expand with the foam body from a delivery configuration to a deployed configuration, the expandable frame comprising:
a proximal hub and a plurality of recapture struts configured to extend radially outwardly from the proximal hub in the deployed configuration; and
a tubular body comprising a plurality of sidewall struts, the tubular body defining a central axis and extending distally from the plurality of recapture struts and configured to press the sidewall of the foam body into conforming contact with a wall of the left atrial appendage in the deployed configuration; and
a plurality of anchors coupled with the tubular body and configured to extend radially outwardly through the sidewall to engage tissue of the left atrial appendage in the deployed configuration.
