4. The device of claim 3 , further including at least one porous element attached to the outer wall, and being shaped to cover the at least one opening.

5. The device of claim 4 , wherein the at least one porous element has an annular shape.

6. A device for adjusting the shape of a coronary sinus, the device comprising:

a flexible tube sized and configured to be positioned in the coronary sinus, the flexible tube having:

an outer wall extending between a proximal end and a distal end;

a first bore defined by the outer wall and extending from the proximal end to the distal end;

a proximal flange attached to the proximal end;

a distal flange attached to the distal end;

wherein, the first bore is filled with a fluid adhesive;

wherein the outer wall includes a plurality of hinge regions, and at least one opening defined between two adjacent hinge regions, thereby creating a passage between first bore and a space outside the flexible tube; and

a porous element attached to the outer wall, the porous element being shaped to cover the at least one opening.

7. The device of claim 6 , wherein the proximal flange defines a proximal opening, and an inner member passes slidingly through the proximal opening and extends to, and is connected to, the distal flange.

8. The device of claim 7 , wherein the inner member defines a plurality of teeth which act as a ratchet for passing slidingly through the proximal opening, the proximal opening configured to act as a pawl.

9. The device of claim 7 , wherein the inner member defines a second bore extending along an entire length of the inner member.

10. The device of claim 6 , wherein the porous element is shaped to have an annular shape.

11. A method for adjusting the shape of a coronary sinus in a heart of a patient, comprising:

inserting a tube into a coronary sinus of the heart, the tube having:

an outer wall extending linearly between a proximal end and a distal end, the outer wall including a plurality of hinge regions,

a first bore defined by the outer wall and extending from the proximal end to the distal end,

a proximal flange attached to the proximal end,

a distal flange attached to the distal end,

at least one opening defined between two adjacent hinge regions, thereby creating a passage between the first bore and a space outside the tube, and

a porous element attached to the outer wall, the porous element being shaped to cover the at least one opening;

introducing a fluid adhesive into the bore;

expelling a first amount of the fluid adhesive from the bore through the plurality of openings and, thereby, allowing the tube to become attached to an inner wall of the coronary sinus at a plurality of points adjacent the plurality of openings; and

shortening the tube in the direction of the elongate axis, and thereby shortening the coronary sinus.

12. The method of claim 11 , further including, adding a curing agent into the bore, thereby causing the fluid adhesive in the bore to harden.

13. The method of claim 11 , further including, introducing a source of ultraviolet light into the bore, thereby causing the fluid adhesive in the bore to harden.

14. The method of claim 11 , further including bending the tube.

15. The method of claim 14 , wherein bending the tube includes applying a longitudinal compression force to the tube in the direction of the elongate axis.

16. The method of claim 11 , wherein expelling an amount of fluid adhesive includes reducing a volume of the bore.

17. The method of claim 11 , wherein expelling a first amount of fluid adhesive includes adding a second amount of fluid adhesive into the bore.

18. A device for adjusting the shape of a coronary sinus, the device comprising:

a flexible having:

an outer wall extending between a proximal end and a distal end;

a first bore defined within the outer wall and extending from the proximal end to the distal end;

a proximal flange attached to the proximal end;

a distal flange attached to the distal end;

wherein, the first bore is filled with a fluid adhesive;

wherein the outer wall includes a plurality of hinge regions, and at least one opening defined between two adjacent hinge regions, thereby creating a passage between first bore and a space outside the flexible tube; and

a porous element attached to the outer wall, the porous element being shaped to cover the at least one opening; and

the proximal flange defines a proximal opening, and an inner member passes slidingly through the proximal opening and extends through the first bore and is connected to the distal flange.
