## Abstract

Described are methods and systems for treating a patient to modify a body passage of the patient. The methods may involve removing tissue from a luminal surface of a body passage such as the esophagus or stomach, for the purpose of inducing a healing response that will result in a reshaping of the body passage.

## Claims

### Claim 1

A medical device, comprising:
an endoscopic ligator barrel;
one or more ligation bands received upon the ligation barrel; and
a single pull line operably associated with said one or more ligation bands, said single pull line operable to deploy said one or more ligation bands from said ligation barrel.

### Claim 2 (depends on 1)

The medical device of claim 1 further comprising an endoscope, with said endoscopic ligator barrel received upon said endoscope.

### Claim 3 (depends on 1)

The medical device of claim 1, wherein said ligator barrel has a proximal end and a distal end, and wherein said distal end is beveled.

### Claim 4 (depends on 1)

The medical device of claim 1, wherein said ligator barrel is provided with calibrations for determining an amount of tissue received in the ligator barrel.

### Claim 5 (depends on 2)

The medical device of claim 2 further comprising an endoscopic video system.

### Claim 6 (depends on 2)

The medical device of claim 2 further comprising an electrocautery snare which extends through said endoscope.

### Claim 7

A medical device, comprising:
an endoscopic ligator barrel having a proximal end and a beveled distal end; and
one or more ligation bands received upon the ligation barrel, said one or more ligation bands being deployable from said beveled distal end.

### Claim 8 (depends on 7)

The medical device of claim 7, wherein said ligator barrel is provided with calibrations for determining an amount of tissue received in the ligator barrel.

### Claim 9 (depends on 7)

The medical device of claim 7, wherein said one or more ligation bands are positioned along a longitudinal segment of the endoscopic ligator barrel, and wherein the circumference of the barrel is substantially constant along the length of said longitudinal segment.

### Claim 10 (depends on 7)

The medical device of claim 7 further comprising one or more pull lines operably associated with said one or more ligation bands, said one or more pull lines being operable to deploy said one or more ligation bands from said ligation barrel.

### Claim 11 (depends on 10)

The medical device of claim 10 having a single pull line.

### Claim 12 (depends on 10)

The medical device of claim 10 including a pull line extending through said endoscopic ligator barrel.

### Claim 13 (depends on 12)

The medical device of claim 12 having a single pull line.

### Claim 14 (depends on 12)

The medical device of claim 12, wherein said pull line exits the beveled, distal end of the barrel substantially at the long side of the barrel.

### Claim 15 (depends on 10)

The medical device of claim 10 including a pull line comprising a plurality of engagement members configured to reside against and facilitate movement of said one or more ligation bands as the pull line is pulled.

### Claim 16 (depends on 15)

The medical device of claim 15 having a single pull line.

### Claim 17 (depends on 7)

The medical device of claim 7 further comprising an endoscope, with said endoscopic ligator barrel received upon said endoscope.

### Claim 18 (depends on 17)

The medical device of claim 17 further comprising an endoscopic video system.

### Claim 19 (depends on 17)

The medical device of claim 17 further comprising an electrocautery snare which extends through said endoscope.
