## Abstract

A granule delivery system contains a plunger and a divided tube, wherein the divided tube has two or more partial shells which are suitable to be coupled to each other, so that a longitudinal channel is formed in the divided tube, each of the partial shells is able to move longitudinally in relation to the other, and the plunger is able to be inserted into the longitudinal channel, when the two or more partial shells are coupled to each other.

## Claims

### Claim 1

A method of delivering granules into a space comprising the following steps:
a) preparing a granule delivery system including a plunger and a divided tube, wherein the divided tube comprises two or more partial shells which are adapted to be coupled to each other, so that a longitudinal channel is formed in the divided tube, each of the partial shell is able to move longitudinally in relation to the other, and said plunger is adapted to be inserted into said longitudinal channel, when said two or more partial shells are coupled to each other;
b) introducing granules into the longitudinal channel formed in the divided tube;
c) inserting the plunger into the channel of the divided tube to an extent so that the plunger contacts the granules; and
d) withdrawing said two or more partial shells at the same time or one-by-one to expose the granules from the divided tube.

### Claim 2 (depends on 1)

The method of claim 1 wherein the granule delivery system further includes a holder, the divided tube is adapted to be slidably held by said holder, and the partial shells of the divided tube held by said holder are able to move longitudinally in relation to said holder.

### Claim 3 (depends on 2)

The method of claim 2 further comprising an engaging means for allowing the longitudinal movement between the partial shells and the holder only in one direction.

### Claim 4 (depends on 3)

The method of claim 3, wherein said engaging means comprises an elastic clip provided on each of said partial shells, and a series of parallel detents corresponding to said elastic clip provided on the holder at a regular interval longitudinally, so that the elastic clip is ratchetingly engaged with the series of parallel detents.

### Claim 5 (depends on 1)

The method of claim 1 wherein said two or more partial shells are two half shells.

### Claim 6 (depends on 1)

The method of claim 1 wherein said two or more partial shells are two half shells.

### Claim 7 (depends on 1)

The method of claim 1 further comprising granules adapted to be introduced into the longitudinal channel.

### Claim 8 (depends on 1)

The method of claim 1 further comprising repeating the withdrawing in step d), so that more granules in the divided tube are exposed from the divided tube.

### Claim 9 (depends on 1)

The method of claim 1 further comprising e) moving the divided tube so that the divided tube is separated from the exposed granules.
