1. An embolic containment device, comprising:
- an expandable frame that is moveable between a collapsed configuration and an expanded configuration, the expandable frame having a proximal hub and a distal hub;
a plurality of supports each having a jogged portion and a length extending between the proximal hub and the distal hub, the length defining a longitudinal axis of each support when the frame is in the collapsed configuration, wherein the support extends continuously from the proximal hub of the frame to the distal hub of the frame through the jogged portion; and
a plurality of tissue anchors integrally formed and attached to supports, said anchors extending alongside a portion of said supports and having tissue engagement ends extending, when the frame is in the collapsed configuration, outwardly beyond an outer surface of the expandable frame and generally toward the proximal hub;
wherein the supports have an aspect ratio that decreases in said portion alongside said anchors to form a bending region of said supports, and said anchors are attached proximal to a jogged portion along the length of a corresponding support, said jogged portion turning at least partially laterally away from the longitudinal axis of said support when the frame is in the collapsed configuration.

Abstract
A device for containing emboli within a left atrial appendage of a patient includes a frame that is expandable from a reduced cross section to an enlarged cross section and a slider assembly. There is provided in accordance with various embodiments of the present invention methods of preventing retention anchors from projecting outside of the native diameter of the frame, thus facilitating recapture of the device.
