## Abstract

A surgical instrument includes a hollow member having a sidewall provided with a window and a closure member movably connected to the hollow member for alternately covering and uncovering the window. The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other.

## Claims

### Claim 1

A surgical method comprising:
providing an instrument assembly including a hollow body member having a sidewall formed with a window and further including a tissue occlusion component, said occlusion component defining a pair of jaws, at least one of said jaws including an arcuate clamping surface;
inserting said hollow body member into a body lumen of a patient;
manipulating said hollow body member so that organic tissues protrude through said window into said hollow body member;
after the protruding of said tissues through said window, manipulating said occlusion component so that said jaws are located on opposite sides of the protruding tissues;
thereafter closing said jaws to clamp the protruding tissues; and
subsequently operating said occlusion component to permanently constrict a portion of said protruding tissues without transecting said protruding tissues to effect ischemic regression of said protruding tissues.

### Claim 2 (depends on 1)

The method of defined claim 1 wherein said instrument assembly includes a shutter or closure member for covering said window, wherein the inserting of said hollow body member into the body lumen includes inserting said hollow body member with said shutter or closure member covering said window, further comprising moving said shutter or closure member to uncover said window to permit said organic tissues to protrude through said window.

### Claim 3 (depends on 2)

The method defined in claim 2, wherein the moving of said shutter or closure member includes sliding said shutter or closure member relative to said hollow body member.

### Claim 4 (depends on 1)

The method defined in claim 1, further comprising attaching said hollow body member to an insertion member of an endoscope, the inserting of said hollow body member into said body lumen including inserting said endoscope with said hollow body member attached thereto into said body lumen.

### Claim 5 (depends on 4)

The method defined in claim 4 wherein said hollow body member has a channel and a chamber, said window communicating with said chamber, the attaching of said hollow body member to said insertion member including inserting said insertion member into said channel, further comprising visualizing the protruding tissues in said chamber via an optical system having access to said chamber.

### Claim 6

A surgical method comprising:
providing an instrument assembly including a hollow body member having a sidewall formed with a window and further including a tissue occlusion component, said occlusion component defining a pair of jaws, at least one of said jaws including an arcuate clamping surface;
inserting said hollow body member into a body lumen of a patient;
manipulating said hollow body member so that organic tissues protrude through said window into said hollow body member;
after the protruding of said tissues through said window, manipulating said occlusion component so that said jaws are located on opposite sides of the protruding tissues;
thereafter closing said jaws to clamp the protruding tissues; and
subsequently operating said occlusion component to permanently constrict a portion of said protruding tissues without transecting said protruding tissues to effect ischemic regression of said protruding tissues;
wherein the method is provided for treatment of hemorrhoids and inserting said hollow body member into a body lumen of a patient includes inserting the hollow body member into an anal canal of the patient.
