## Abstract

The present invention relates to a novel cap and plug device for occluding a fistula in a patient. This device has improved success rates over prior devices.

## Claims

### Claim 1

A device for occluding a fistula tract in a patient comprising:
a) a plug body designed for insertion into the fistula tract; and
b) a cap constructed of a medically acceptable material, attached to the plug body and designed to surgically attach the device to the patient, the cap comprising:
a) a planar body portion attached to the plug body; and
b) an edge portion that is thicker than the planar body portion, the edge portion of a shape designed to conform to a suture placed through the planar body, wherein at least a portion of the suture wraps around the edge portion and is attached to the patient.

### Claim 2 (depends on 1)

The device according to claim 1 wherein a cross section of the edge portion is circular.

### Claim 3 (depends on 1)

The device according to claim 1 wherein the medically acceptable material is selected from the group consisting of silicone, poly(lactic-co-glycolic acid), and poly(dimethyl siloxane).

### Claim 4 (depends on 1)

The device according to claim 1 which has a fiber reinforcement positioned in at least a portion of the device.

### Claim 5 (depends on 4)

The device according to claim 4 wherein the fiber reinforcement is positioned in the planar body portion.

### Claim 6 (depends on 4)

The device according to claim 4 wherein the fiber is constructed of a composition selected from the group consisting of poly(propylene), poly(amide), and poly(ester).

### Claim 7 (depends on 1)

The device according to claim 1 wherein the cap is circular.

### Claim 8

A cap device for use in surgically attaching a medical device attached to the cap to a patient, the cap comprising:
c) a planar body portion attached to the plug body; and
d) an edge portion that is thicker than the planar body portion, the edge portion of a shape designed to conform to a suture placed through the planar body, wherein at least a portion of the suture wraps around the edge portion.

### Claim 9 (depends on 8)

The device according to claim 8 wherein a cross section of the edge portion is circular.

### Claim 10 (depends on 8)

The device according to claim 8 wherein the medically acceptable material is silicone.

### Claim 11 (depends on 8)

The device according to claim 8 which has a fiber reinforcement positioned in at least a portion of the device.

### Claim 12 (depends on 11)

The device according to claim 11 wherein the fiber reinforcement is positioned in the planar body portion.

### Claim 13 (depends on 11)

The device according to claim 11 wherein the fiber is constructed of a composition selected from the group consisting of poly(propylene), poly(amide), and poly(ester).

### Claim 14 (depends on 8)

The device according to claim 8 wherein the cap is circular.
