Abstract

Device (2) for administering a composition in a duct (14) of a human or animal body, comprising means (4) able to enter an inner surface of the duct wall to make blind openings in a thickness of the wall and dispenser means (20) to place the composition in contact with the openings.

Claims

1. Device (2;

102) for administering a composition in a wall of a duct (14) of a human or animal body, which comprises means (4;

104) to enter an inner surface (12) of the duct wall to make blind openings (36) in a thickness of the wall, and dispensing means (20;

120) to place the composition in contact with the openings.

2. Device according to claim 1, wherein the entry means (4;

104) comprise cutting parts (116) or perforating parts (16).

3. Device according to claim 1, wherein the entry means (4;

104) are radially expandable relative to an axial direction of the device.

4. Device according to any claim 1, wherein the entry means (4;

101) are associated with an inflatable chamber (6;

106).

5. Device according to claim 4, wherein the cutting or perforating means (16) are carried by a wall of the inflatable chamber (6).

6. Device according to claim 2, wherein the entry means comprise arms (140) carrying the cutting or perforating parts (116).

7. Device according to claim 6, wherein the arms (140) are associated with a tube on which an inflatable chamber (8) is mounted.

8. Device according to claim 1, wherein the dispenser means (120) are radially extensible relative to an axial direction of the device.

9. Device according to claim 1, wherein the dispenser means (20) have channels (24) able to receive the composition, the channels being open in a direction opposite to an axis of the device or closed by a wall containing openings.

10. Device according to claim 1, wherein the dispenser means (20;

120) comprise a wall having outer openings (124).

11. Device according to claim 1, wherein the dispenser means (20;
