Methods and systems for endovascularly clipping and repairing lumen and tissue defects
First Claim
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.

Abstract
An implantable closure structure is delivered using minimally invasive techniques, and inhibits the migration of liquid and particulate matter from inside a physiological cavity or opening, such as an aneurysm or a septal defect, as well as inhibiting the flow of liquid and particulate matter, such as from an associated blood vessel or chamber, into the physiological cavity or opening. The device has a closure structure that covers the neck or opening of a cavity and has one or more anchoring structures for supporting and retaining the closure structure in place across the cavity or opening.

15. A device for treating a tissue defect in a physiological lumen of a human subject, wherein the device is selectively transformable between a low profile delivery configuration and a deployed configuration sized to fit within the opening of the tissue defect, and wherein, in the deployed configuration, the device comprises:
a closure system configured to repair and/or occlude an opening of the tissue defect in the physiological lumen, the closure system including— a radially expandable collar structure configured to engage tissue on or proximate the opening; a closure structure coupled to the collar structure and positioned within the collar structure, wherein the closure structure is sized to substantially cover the opening; and expandable atraumatic anchoring structures distributed around a circumference of the collar structure and configured to engage tissue above and below the opening, wherein the expandable atraumatic anchoring structures include at least a first anchoring structure extending in a first direction from a plane defined by the closure structure and a second anchoring structure extending in a second, opposite direction from the plane defined by the closure structure, wherein the first and second anchoring structures are integrally formed and comprise a single looped structure, and wherein the first anchoring structure is positioned to engage tissue in a cavity of the tissue defect and above the opening, and the second anchoring structure opposite the first anchoring structure is positioned to engage tissue outside the cavity and below the opening. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An implantable device configured for placement at an opening of a physiological cavity, the implantable device comprising:
-
a neck structure having an outer surface configured to be positioned in proximity to the opening of the physiological cavity; a plurality of anchoring structures including at least a first anchoring structure projecting from the neck structure in a first direction toward the cavity and a second anchoring structure integrally formed with the first anchoring structure projecting from the neck structure in a second direction opposite the first direction and away from the cavity, wherein the first and second anchoring structures are integrally formed and comprise a generally atraumatic, single looped structure; and a closure structure positioned within an interior of the neck structure, the closure structure configured to occlude the opening, wherein the implantable device is selectively transformable between a delivery condition and a deployed condition sized to fit within the opening of the physiological cavity. - View Dependent Claims (26, 27, 28, 29)
