Catheter device with longitudinally expanding interior components for compressing cancellous bone

1. An apparatus for compacting cancellous bone during a procedure comprising:

a first tube with a beveled distal end;

a second tube with a proximal end distal to the beveled distal end of the first tube;

a third tube in which the first tube and second tube are located; and

an expandable member with a proximal end secured proximal to the beveled distal end of the first tube and a distal end secured distal to the proximal end of the second tube;

wherein the first tube is operable to deliver inflation medium into the expandable member through the beveled distal end, and

wherein the second tube moves in a distal direction from the beveled distal end of the first tube during inflation of the expandable member.

2. The apparatus of claim 1 , wherein the third tube is bonded to the expandable member.

3. The apparatus of claim 1 , wherein the third tube is pellethane.

4. The apparatus of claim 1 , wherein the second tube moves in a proximal direction toward the beveled distal end of the first tube during deflation of the expandable member.

5. The apparatus of claim 1 , wherein the expandable member expands in a longitudinal direction in addition to a radial direction upon inflation.

6. The apparatus of claim 1 , wherein inflation medium is introduced into an interior of the balloon using an actuator.

7. The apparatus of claim 1 , wherein first and second ends of the expandable member are bonded directly to the third tube.

8. The apparatus of claim 1 , wherein the third tube is elastic and stretches during inflation of the expandable member and contracts during deflation of the expandable member.

9. The apparatus of claim 1 , wherein the balloon has a plurality of pleats.

10. The apparatus of claim 1 , further comprising a shim.
