Abstract
Abstract Disclosed is a closure catheter, for patching a tissue opening such as an atrial septal defect, patent foreman ovale, or the left atrial appendage of the heart. The closure catheter carries a deployable patch and a plurality of tissue anchors, which may be deployed to secure the patch to surrounding tissue. Methods are also disclosed.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
52 words
A method of closing an opening in a subcutaneous tissue plane, comprising the steps of: providing a catheter having a patch and at least one anchor thereon; advancing the catheter to the opening; positioning the patch across the opening; and advancing the anchor into tissue to secure the patch across the opening.
Claim 2
Independent Claim
52 words
A method of closing an opening in a subcutaneous tissue plane, comprising the steps of: providing a catheter having a patch and at least one anchor thereon; advancing the catheter to the opening; positioning the patch across the opening; and advancing the anchor into tissue to secure the patch across the opening.
Claim 3
Dependent Claim
33 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the advancing the catheter step comprises advancing a distal portion of the catheter through the opening.
Claim 4
Dependent Claim
33 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the advancing the anchor step comprises advancing the anchor through the patch and into the tissue.
Claim 5
Dependent Claim
38 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the advancing the anchor step comprises advancing at least three anchors into the tissue to secure the patch across the opening.
Claim 6
Dependent Claim
24 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the opening is a naturally occurring opening.
Claim 7
Dependent Claim
24 words
A method of closing an opening in a subcutaneous tissue plane as in claim 5 , wherein the opening is an atrial septal defect.
Claim 8
Dependent Claim
24 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the opening is a surgically created opening.
Claim 9
Dependent Claim
39 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , further comprising the step of unfolding the patch from a reduced configuration to an enlarged configuration prior to the advancing the anchor step.
Claim 10
Dependent Claim
97 words
A method of closing an opening in a subcutaneous tissue plane as in claim 1 , wherein the catheter comprises: an elongate, flexible body, having a proximal end and a distal end, and a longitudinal axis extending therebetwee; at least two anchor supports on the distal end, the anchor supports moveable between a first position in which they are substantially parallel with the axis, and a second position in which they are inclined laterally from the axis; and a control on the proximal end for moving the anchor supports from the axial orientation to the inclined orientation.
Claim 11
Dependent Claim
30 words
A method of closing an opening in a subcutaneous tissue plane as in claim 9 , wherein the catheter comprises from about three anchor supports to about eight anchor supports.
Claim 12
Dependent Claim
25 words
A method of closing an opening in a subcutaneous tissue plane as in claim 9 , wherein at least one anchor support comprises a tube.
Claim 13
Dependent Claim
26 words
