## Abstract

An exemplary valve repair device for repairing a native valve of a patient includes: a strip of material; a coaption element formed from the strip of material; and a pair of paddles formed from the strip of material and connected to the coaption element. The paddles are movable between an open position and a closed position and the paddles are configured to attach to the native valve of the patient.

## Claims

### Claim 1

A method of manufacturing a valve repair device for repairing a native valve of a patient, the method comprising:
folding a strip of material to form at least a portion of a coaption element and at least a portion of a pair of paddles connected to the coaption element, wherein the paddles are movable between an open position and a closed position and are configured to attach to the native valve of the patient;
attaching a first portion of the strip of material to a collar; and
attaching a second portion of the strip of material to a cap, such that movement of the cap toward the collar causes the pair of paddles to move to the closed position, and movement of the cap away from the collar causes the pair of paddles to move to the open position.

### Claim 2 (depends on 1)

The method of claim 1, wherein the strip of material comprises metal strands that are woven together.

### Claim 3 (depends on 1)

The method of claim 1, wherein the strip of material comprises an electrospun material.

### Claim 4 (depends on 1)

The method of claim 1, wherein the strip of material comprises electrospun metal fibers.

### Claim 5 (depends on 1)

The method of claim 1, wherein the paddles comprise an inner paddle portion and an outer paddle portion.

### Claim 6 (depends on 1)

The method of claim 1, wherein the strip of material is folded to form the coaption element and the pair of paddles.

### Claim 7 (depends on 1)

The method of claim 1, wherein the strip of material is folded to form a plurality of layers.

### Claim 8 (depends on 7)

The method of claim 7, wherein the coaption element is formed from four layers of the strip of material.

### Claim 9 (depends on 7)

The method of claim 7, wherein the paddles comprise an inner paddle portion and an outer paddle portion, and the inner paddle portion is formed from two layers of the folded strip of material.

### Claim 10 (depends on 1)

The method of claim 1, wherein the paddles are disposed over an extension member.

### Claim 11 (depends on 10)

The method of claim 10, wherein the extension member comprises a hoop and the strip of material is folded around the hoop.

### Claim 12 (depends on 11)

The method of claim 11, wherein the paddles comprise an inner paddle portion and an outer paddle portion and the fold of the strip of material around the hoop is arranged between the inner and outer paddle portions.

### Claim 13 (depends on 1)

The method of claim 1, wherein the strip of material extends from a beginning in the paddle portion to an end in the paddle portion.

### Claim 14 (depends on 13)

The method of claim 13, wherein the paddles comprise an inner paddle portion and an outer paddle portion, and wherein the beginning and end of the strip of material are located in the inner paddle portions.

### Claim 15 (depends on 1)

The method of claim 1, further comprising a base assembly that comprises:
a shaft;
a collar that the shaft extends through; and
a cap attached to the shaft such that the cap can be moved by the shaft away from the collar;
wherein the pair of paddles are attached to the cap; and
wherein movement of the cap toward the collar causes the pair of paddles to move to the closed position, and movement of the cap away from the collar causes the pair of paddles to move to the open position.

### Claim 16 (depends on 1)

The method of claim 1, wherein the coaption element is configured to close a gap in the native valve of the patient when the valve repair device is attached to the native valve.
