Abstract
Abstract Disclosed is a closure catheter, for closing 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 plurality of tissue anchors, which may be deployed into tissue surrounding the opening, and used to draw the opening closed. Methods are also disclosed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
114 words
An atrial septal closure catheter, comprising: an elongate, flexible body, having a proximal end and a distal end and a longitudinal axis extending therebetween; at least two supports on the distal end, the supports movable from a first position in which they are substantially parallel with the axis, and a second position in which they are inclined with respect to the axis; a control on the proximal end for moving the supports from the first position to the second position; and at least one anchor carried by each support, each anchor secured to an anchor suture wherein the supports incline radially outwardly in the proximal direction when the supports are in the second position.
Claim 2
Dependent Claim
114 words
An atrial septal closure catheter, comprising: an elongate, flexible body, having a proximal end and a distal end and a longitudinal axis extending therebetween; at least two supports on the distal end, the supports movable from a first position in which they are substantially parallel with the axis, and a second position in which they are inclined with respect to the axis; a control on the proximal end for moving the supports from the first position to the second position; and at least one anchor carried by each support, each anchor secured to an anchor suture wherein the supports incline radially outwardly in the proximal direction when the supports are in the second position.
Claim 3
Dependent Claim
27 words
An atrial septal closure catheter as in claim 1 , further comprising an anchor deployment actuator for deploying the anchors from the supports in a proximal direction.
Claim 4
Dependent Claim
16 words
An atrial septal closure catheter as in claim 1 , further comprising at least three supports.
Claim 5
Dependent Claim
27 words
An atrial septal closure catheter as in claim 1 , further comprising at least one anchor carried by each support, each anchor secured to an anchor suture.
Claim 6
Dependent Claim
27 words
An atrial septal closure catheter as in claim 4 , further comprising an anchor deployment actuator for deploying the anchors from the supports in a proximal direction.
Claim 7
Dependent Claim
131 words
A closure catheter for closing an atrial septal defect, comprising: an elongate, flexible tubular body, having a proximal end and a distal end and a longitudinal axis extending therebetween; at least two anchor supports on the distal end, the anchor supports movable between an axial position in which they are substantially parallel with the longitudinal axis, and an inclined position in which they are inclined laterally away from the axis; and a control on the proximal end, for moving the anchor supports between the axial and the inclined positions; wherein each anchor support has a proximal end and a distal end, and the distal end is pivotably secured to the catheter so that the proximal end moves away from the axis when the anchor support is moved into the inclined position.
Claim 8
Dependent Claim
131 words
A closure catheter for closing an atrial septal defect, comprising: an elongate, flexible tubular body, having a proximal end and a distal end and a longitudinal axis extending therebetween; at least two anchor supports on the distal end, the anchor supports movable between an axial position in which they are substantially parallel with the longitudinal axis, and an inclined position in which they are inclined laterally away from the axis; and a control on the proximal end, for moving the anchor supports between the axial and the inclined positions; wherein each anchor support has a proximal end and a distal end, and the distal end is pivotably secured to the catheter so that the proximal end moves away from the axis when the anchor support is moved into the inclined position.
Claim 9
Dependent Claim
24 words
A closure catheter for closing an atrial septal defect as in claim 6 , further comprising an anchor in each of the anchor supports.
Claim 10
Dependent Claim
23 words
A closure catheter for closing an atrial septal defect as in claim 6 , comprising from about four to about ten anchor supports.
Claim 11
Dependent Claim
22 words
A closure catheter for closing an atrial septal defect as in claim 6 , further comprising a suture connected to each anchor.
Claim 12
Dependent Claim
27 words
A closure catheter for closing an atrial septal defect as in claim 6 , further comprising a clamp removably carried by the distal end of the catheter.
Claim 13
Dependent Claim
19 words
A closure catheter as in claim 6 , comprising from about three anchor supports to about eight anchor supports.
Claim 14
Dependent Claim
17 words
A closure catheter as in claim 6 , wherein at least one anchor support comprises a tube.
Claim 15
Dependent Claim
18 words
A closure catheter as in claim 12 , further comprising a tissue anchor moveably positioned within the tube.
Claim 16
Dependent Claim
17 words
A catheter as in claim 6 , wherein the anchor support is biased toward the inclined orientation.
Claim 17
Dependent Claim
15 words
A catheter as in claim 6 , wherein the control comprises an axially moveable actuator.
Claim 18
Dependent Claim
37 words
A catheter as in claim 15 , wherein the actuator comprises a core connected to the anchor support such that axial movement of the core advances the anchor support from the axial orientation to the inclined orientation.
Claim 19
Dependent Claim
23 words
A catheter as in claim 15 , further comprising an introducer removably connected to the anchor for driving the anchor into the tissue.
Claim 20
Dependent Claim
21 words
A catheter as in claim 17 , where in the anchor comprises a tubular body and the introducer extends axially therethrough.
