Claim 0:
1. A system for occluding a left atrial appendage, comprising:
a delivery device including an outer sheath and an inner elongate member slidably disposed within a lumen of the outer sheath;
an implant configured to occlude the left atrial appendage comprising:
an expandable framework configured to shift between a collapsed configuration when disposed within the outer sheath and an expanded configuration when disposed outside of the outer sheath, wherein the expandable framework includes an attachment point configured to releasably secure the expandable framework to the delivery device; and
an occlusive element disposed on a proximal portion of the expandable framework, wherein the occlusive element covers the attachment point, the occlusive element defining a proximalmost surface of the implant across an entirety of the implant;
wherein the attachment point includes a cam member extending laterally across a proximal hub of the expandable framework and having a convex distal facing surface defined by an axis oriented perpendicular to the cam member, the cam member including a convex first lateral shoulder and a convex second lateral shoulder forming a channel in the convex distal facing surface of the cam member;

and
a tether extending longitudinally within a lumen of the inner elongate member, the tether engaging the attachment point in a delivery configuration;
wherein the tether passes through the occlusive element and extends around the convex distal facing surface of the cam member within the channel formed in the convex distal facing surface in the delivery configuration.
