1. A method of occluding a cavity of a patient with an occluder, the method comprising:
advancing a delivery catheter through vasculature of the patient until a distal end of the delivery catheter is positioned proximate to the cavity or within the cavity;
when the distal end of the delivery catheter is positioned proximate to the cavity or within the cavity, advancing a distal body portion of the occluder relative to the delivery catheter to allow the distal body portion to transition from a collapsed condition within the delivery catheter to an expanded condition outside of the delivery catheter;
positioning the distal body portion of the occluder within the cavity;
engaging protrusions extending from the distal body portion into frictional engagement with tissue that defines the cavity;
deploying a proximal abutment portion of the occluder from the delivery catheter such that the proximal abutment portion is, after deployment, oriented generally perpendicular to an axis of the cavity; and
positioning the proximal abutment portion against tissue of a wall forming an opening that leads into the cavity, such that the distal body portion is positioned within the cavity, the proximal abutment portion is positioned outside the cavity, and a transition member of the occluder extends through the opening and connects the distal body portion to the proximal abutment portion, the transition member having a diameter that is smaller than a diameter of the distal body portion and smaller than a diameter of the proximal abutment portion, at least a portion of the transition member being positioned radially inwardly of the distal body portion when the distal body portion is positioned within the cavity and the proximal abutment portion is positioned against tissue of the wall.
