Claim Text:
1. An implantable device for repairing an opening or cavity in a target tissue defect, the implantable device being adjustable from a delivery condition in which it assumes a generally small diameter configuration to a deployed condition in which it assumes a larger diameter configuration, the implantable device comprising: a closure structure sized to substantially cover the opening or cavity when the device is in the deployed condition; a collar structure provided in proximity to a perimeter of the closure structure, the collar structure configured to engage at least a portion of tissue at the opening or cavity when the device is in the deployed condition; a first anchoring structure extending in a first direction from a plane defined by the closure structure when the device is in the deployed condition; and a second anchoring structure extending in a generally opposite second direction from the plane defined by the closure structure when the device is in the deployed condition, wherein the first anchoring structure extending in the first direction faces generally toward the tissue defect and the second anchoring structure extending in the second direction faces generally away from the tissue defect, wherein the first and second anchoring structures are integrally formed and comprise a generally atraumatic, single looped structure extending beyond a periphery of the collar structure when the device is in the deployed condition.
