## Abstract

A device for treating acid reflux comprising a sleeve configured and dimensioned for insertion into the esophagus of the patient, the sleeve having a proximal portion, a distal portion and an intermediate portion between the distal and proximal portions. The sleeve includes a an inner member applying a radial force on the sleeve for securement within the esophagus, and a skirt connected to the sleeve to block acid backup from the stomach while not inhibiting passage of food into the stomach.

## Claims

### Claim 1

A device for treating acid reflux comprising a sleeve configured and dimensioned for insertion into an esophagus of a patient, the sleeve having a proximal portion, a distal portion and an intermediate portion between the distal and proximal portions, the sleeve including an inner member extending from a proximal region of the sleeve to a distal region of the sleeve, the inner member applying a radial force on the sleeve along a length thereof for securement within the esophagus, and a skirt connected to the sleeve to block acid backup from a stomach while not inhibiting passage of food into the stomach, the skirt positioned within the sleeve and axially spaced from the inner member, the skirt movable between an open position and a closed blocking position within the sleeve, wherein the skirt includes a plurality of flaps extending toward the inner member when food passes through the skirt toward the stomach.

### Claim 2 (depends on 1)

The device of claim 1, wherein the inner member is formed in a spiral shape.

### Claim 3 (depends on 1)

The device of claim 1, wherein the sleeve has a retrieval structure at the proximal portion for retrieval of the sleeve.

### Claim 4 (depends on 3)

The device of claim 3, wherein the retrieval structure includes a hook or ball tip.

### Claim 5 (depends on 1)

The device of claim 1, wherein the inner member comprises a helical coil in the form of a wire.

### Claim 6 (depends on 1)

The device of claim 1, wherein the inner member includes a spiral configuration having a double helix configuration.

### Claim 7 (depends on 1)

The device of claim 1, further comprising a plurality of tines extending externally of the sleeve to grasp a wall of the esophagus.

### Claim 8 (depends on 1)

The device of claim 1, wherein the skirt is positioned proximal of the inner member.

### Claim 9 (depends on 8)

The device of claim 8, wherein the sleeve has a proximal edge and the skirt is positioned distal of the proximal edge.

### Claim 10 (depends on 1)

The device of claim 1, wherein the plurality of flaps overlap.

### Claim 11 (depends on 1)

The device of claim 1, wherein the inner member comprises a mesh.

### Claim 12 (depends on 1)

The device of claim 1, wherein the inner member comprises a stent-like body.

### Claim 13 (depends on 1)

The device of claim 1, further comprising a second skirt within the inner member axially spaced from the skirt.
