Claim 1
Independent Claim
73 words
A method of patching an atrial septal defect, comprising the steps of: providing a catheter having an elongate, flexible body with a proximal end and a distal end, a patch and at least two anchors removably carried by the distal end; advancing the distal end to a position near the atrial septal defect; positioning the patch across the defect; and deploying the anchors from the catheter to secure the patch across the defect.

Claim 3
Dependent Claim
41 words
A method of patching an atrial septal defect as in claim 1 , wherein the positioning step comprises enlarging the cross section of the patch from a reduced profile for advancing the catheter to an enlarged profile for patching the defect.
Claim 4
Dependent Claim
39 words
A method of patching an atrial septal defect as in claim 1 , wherein the positioning step comprises inclining at least one patch support from an axial orientation to an inclined orientation to position the patch across the defect.
Claim 5
Dependent Claim
39 words
A method of patching an atrial septal defect as in claim 3 , wherein the positioning step comprises inclining at least three patch supports from an axial orientation to an inclined orientation to position the patch across the defect.
Claim 6
Dependent Claim
40 words
A method of patching an atrial septal defect as in claim 3 , wherein the deploying the anchors step comprises advancing the anchors distally through the patch and into tissue adjacent the defect to secure the patch across the defect.
Claim 7
Independent Claim
72 words
A method of closing an opening in a subcutaneous tissue plane, comprising the steps of: providing a catheter having a longitudinal axis, a patch and at least one anchor thereon; advancing the catheter to the opening; positioning the patch across the opening such that the patch is approximately parallel to the tissue plane and transverse to the longitudinal axis; and advancing the anchor into tissue to secure the patch across the opening.
Claim 8
Independent Claim
72 words
A method of closing an opening in a subcutaneous tissue plane, comprising the steps of: providing a catheter having a longitudinal axis, a patch and at least one anchor thereon; advancing the catheter to the opening; positioning the patch across the opening such that the patch is approximately parallel to the tissue plane and transverse to the longitudinal axis; and advancing the anchor into tissue to secure the patch across the opening.
Claim 9
Dependent Claim
33 words
A method of closing an opening in a subcutaneous tissue plane as in claim 6 , wherein the advancing the anchor step comprises advancing the anchor through the patch and into the tissue.
Claim 10
Dependent Claim
38 words
A method of closing an opening in a subcutaneous tissue plane as in claim 6 , wherein the advancing the anchor step comprises advancing at least three anchors into the tissue to secure the patch across the opening.
Claim 11
Dependent Claim
24 words
A method of closing an opening in a subcutaneous tissue plane as in claim 6 , wherein the opening is a naturally occurring opening.
Claim 12
Dependent Claim
24 words
A method of closing an opening in a subcutaneous tissue plane as in claim 9 , wherein the opening is an atrial septal defect.

A patch deployment catheter for deploying a patch across an opening, comprising: an elongate body, having a proximal end and a distal end; at least two supports on the catheter, movable between an axial orientation and an inclined orientation, each support comprising a proximal section, a distal section, and a hinge in between; and a control on the catheter for moving the hinge radially outwardly from a first position for introducing the catheter to a site in the body to a second position for deploying the patch at the site; wherein the supports are in the axial orientation when the hinge is in the first position.
Claim 22
Dependent Claim
106 words
A patch deployment catheter for deploying a patch across an opening, comprising: an elongate body, having a proximal end and a distal end; at least two supports on the catheter, movable between an axial orientation and an inclined orientation, each support comprising a proximal section, a distal section, and a hinge in between; and a control on the catheter for moving the hinge radially outwardly from a first position for introducing the catheter to a site in the body to a second position for deploying the patch at the site; wherein the supports are in the axial orientation when the hinge is in the first position.
