1. An occlusion device for occluding a left atrial appendage, the occlusion device comprising:
a first portion, the first portion comprising a plurality of fingers;
a second portion attached to the first portion; and
at least one of a covering, a graft material, a coating, or a drug for promoting endotheliazation when the occlusion device is implanted in a left atrial appendage,
wherein the occlusion device is plastically deformable from a radially compressed configuration to a radially expanded configuration,
wherein the radially compressed configuration, the plurality of fingers are disposed around a longitudinal axis of the occlusion device,
wherein in the radially expanded configuration, the first portion has a larger cross-sectional profile than the second portion,
wherein the plurality of fingers are unattached to each other except through the second portion, and
wherein the occlusion device is biodegradable.
