## Abstract

According to one aspect of the present invention there is provided a device, preferably a disposable device, for reducing pain, bleeding and/or distension of hemorrhoids during defecation comprising an anchor portion being anchorable against tissue of a rectum and being attached to a tubular portion sized and configured for outwardly biasing internal hemorrhoids (i.e. pushing them against rectal/anal wall tissue) and optionally external hemorrhoids when the anchor portion is preferably anchored against the rectum wall.

## Claims

### Claim 1

A device for reducing pain, bleeding and/or distension of hemorrhoids during defecation and optionally straining, comprising:
(a) a C-shaped discontinuous toroidal balloon configured for anchoring within a lower rectum of a subject when inflated, wherein ends of said balloon are attached via an elastic element capable of elastically stretching when fecal matter transmits through the discontinuous toroidal balloon; and
(b) a tubular mesh structure being elastic along a radial axis thereof, said tubular mesh structure being attached to said balloon when inflated and being for extending through said anal canal;
wherein said balloon and attached tubular mesh structure define a passageway through the device when said balloon is anchored within said lower rectum, said balloon and said tubular mesh structure being radially expandable during defecation when fecal matter is conducted therethrough.

### Claim 2 (depends on 1)

The device of claim 1, wherein said tubular mesh structure is shaped as an hourglass.

### Claim 3 (depends on 1)

The device of claim 1, wherein said tubular mesh structure is coated with silicone.

### Claim 4 (depends on 1)

The device of claim 1, wherein said tubular mesh structure is fabricated from polyester or nylon.

### Claim 5 (depends on 1)

The device of claim 1, wherein said tubular mesh structure is fabricated from a metallic material selected from the group consisting of stainless steel, nitinol, and cobalt chromium.

### Claim 6 (depends on 1)

The device of claim 1, wherein said balloon is a non-compliant balloon.

### Claim 7 (depends on 1)

The device of claim 1, further comprising a tubular sheath for radially constraining said tubular mesh structure in a folded configuration.

### Claim 8 (depends on 7)

The device of claim 7, wherein said tubular sheath includes a mechanism for releasing said tubular mesh structure from said folded configuration.

### Claim 9 (depends on 8)

The device of claim 8, wherein said mechanism tears said sheath.

### Claim 10 (depends on 8)

The device of claim 8, wherein said mechanism removes said sheath.

### Claim 11 (depends on 1)

A system for treating constipation during defecation comprising the device of claim 1 and an applicator for positioning and deploying said device in an anal canal-rectum region of a subject.

### Claim 12 (depends on 1, 11)

The system of claim 11, wherein said applicator includes a lumen for containing the device of claim 1 in a folded configuration.

### Claim 13 (depends on 1, 11)

The system of claim 11, wherein said applicator includes a plunger for ejecting the device of claim 1 from said lumen.

### Claim 14 (depends on 11)

The system of claim 11, wherein said applicator disengages from the device upon inflation of said balloon.

### Claim 15 (depends on 1)

The device of claim 1, wherein said tubular mesh structure is glued, thermally bonded, welded or sutured to said balloon.
