## Abstract

A minimally invasively implanted anchor support for securing a medical device to a heart wall including an anchoring member and an expandable distal anchor retraint which is implanted through the anchoring member, through the heart wall, and expands on the opposing heart wall side to anchor a medical device. A single-stage anchor system includes the distal flange and a two-stage anchor system includes the distal flange and a proximal flange which cooperates with the distal flange to secure a medical device to the heart wall and methods of a single-stage anchor system and a two-stage anchor system.

## Claims

### Claim 1

A minimally invasively implanted anchor support for securing a medical device to a heart wall, the anchor support comprising:
an anchor securing member defining a lumen wherein said anchor securing member is configured to extend through the heart wall;
a distal flange having a proximal end and distal end wherein said distal end of said distal flange includes an anchor restraint configured for securing to a heart wall and said proximal end of said distal flange includes a flex connector and wherein said anchor restraint is expandable and configured for securing to a heart wall a
wherein said anchor restraint of said distal flange is compressed for implantation and when positioned within said anchor securing member lumen during implantation of said anchor support and said anchor securing member lumen is in the heart wall and wherein said anchor restraint extends beyond a distal end of said anchor member lumen and expands against the heart wall for anchoring against the heart wall; and
a proximal flange, said proximal flange comprising an expandable anchor restraint on its distal end and a flexible compression element extending proximally from said proximal flange anchor restraint wherein said anchor restraint of said proximal flange defines a lumen which is positioned along and receives said flex connector of said distal flange for implantation wherein said anchor restraint of said proximal flange contacts the heart wall after implantation on an opposing heart wall of said anchor restraint of said distal flange wherein said anchor restraints of said distal flange and said proximal flange anchor the medical device on the heart wall.

### Claim 2 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said distal flange further comprises a rod extending proximally from said anchor restraint of said distal flange and connecting to said flex connector.

### Claim 3 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said distal flange further comprises a flex connector base on a proximal end of said flex connector.

### Claim 4 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said anchor securing member is an anchor coil.

### Claim 5 (depends on 4)

The minimally invasively implanted anchor support according to claim 4 wherein said anchor coil is a helical coil having a sharp distal tip for penetrating the heart wall.

### Claim 6 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said flex connector is a wire.

### Claim 7 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said flex connector is an expandable coil.

### Claim 8 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said proximal flange further comprises a docking element on a proximal end of said flexible compression element.

### Claim 9 (depends on 8)

The minimally invasively implanted anchor support according to claim 8 wherein said docking element comprises at least one outwardly biased docking arm.

### Claim 10 (depends on 8)

The minimally invasively implanted anchor support according to claim 8 wherein said docking element comprises at least one inwardly biased docking arm.

### Claim 11 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said proximal flange, said flexible compression element and said docking element each define a hollow lumen wherein a continuous lumen extends therethrough.

### Claim 12 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein said flexible compression element is a coil.

### Claim 13 (depends on 1)

The minimally invasively implanted anchor support according to claim 1 wherein a proximal end of said flex connector includes a flex connector base and said minimally invasively implanted anchor support further comprises a tether swivel configured to cooperate with said flex connector base.
