## Abstract

A balloon kyphoplasty surgical device including an extrusion tube having internal fluid channels and a support wire, a port arrangement positioned on a proximal end of the extrusion tube and a balloon arrangement positioned on a distal end of the extrusion tube, the balloon arrangement resulting in a cubic shape when inflated by the port arrangement.

## Claims

### Claim 1

A balloon kyphoplasty surgical device comprising:
an extrusion tube comprising at least three internal fluid channels and a support wire;
a port arrangement positioned on a proximal end of the extrusion tube in fluid communication with the at least three internal fluid channels; and
a balloon arrangement positioned on a distal end of the extrusion tube in fluid communication with the at least three internal fluid channels, the balloon arrangement resulting in a cubic shape when inflated,
wherein the balloon arrangement comprises a plurality of inner balloons housed within an outer balloon; wherein each inner balloon and the outer balloon are in fluid communication with a single fluid channel thereby forming independently inflatable balloons.

### Claim 2 (depends on 1)

The balloon kyphoplasty surgical device of claim 1, wherein each of the plurality of inner balloons is manufactured to produce an inner balloon predetermined shape upon inflation.

### Claim 3 (depends on 2)

The balloon kyphoplasty surgical device of claim 2, wherein the inner balloon predetermined shape further comprises a spherical shape.

### Claim 4 (depends on 2)

The balloon kyphoplasty surgical device of claim 2, wherein the inner balloon predetermined shape further comprises a cylindrical shape.

### Claim 5 (depends on 1)

The balloon kyphoplasty surgical device of claim 1, wherein the outer balloon is manufactured to produce a cubic shape upon inflation.

### Claim 6 (depends on 5)

The balloon kyphoplasty surgical device of claim 5, wherein the port arrangement comprises at least three ports in fluid communication with the at least three internal fluid channels and in fluid communication with at least one inflation device reservoir.

### Claim 7 (depends on 6)

The balloon kyphoplasty surgical device of claim 6, wherein at least two of the at least the ports are configured to inflate the plurality of inner balloons and one of the at least three ports is configured to inflate the outer balloon.

### Claim 8

A kyphoplasty balloon arrangement comprising:
a plurality of inner balloons retained within an outer balloon, wherein the outer balloon is configured to be separately inflatable from the plurality of inner balloons, and wherein each inner balloon and the outer balloon are in fluid communication with a single fluid channel thereby forming independently inflatable balloons.

### Claim 9 (depends on 8)

The kyphoplasty balloon arrangement of claim 8, wherein each inner balloon of the plurality of inner balloons is manufactured to produce a predetermined inner balloon shape upon inflation.

### Claim 10 (depends on 9)

The kyphoplasty balloon arrangement of claim 9, wherein the predetermined inner balloon shape further comprises a spherical shape.

### Claim 11 (depends on 9)

The kyphoplasty balloon arrangement of claim 9, wherein the predetermined inner balloon shape further comprises a cylindrical shape.

### Claim 12 (depends on 8)

The kyphoplasty balloon arrangement of claim 8, wherein the plurality of inner balloons is at least four inner balloons.

### Claim 13 (depends on 8)

The kyphoplasty balloon arrangement of claim 8, wherein the plurality of inner balloons is at least two inner balloons.

### Claim 14 (depends on 8)

The kyphoplasty balloon arrangement of claim 8, wherein the outer balloon is manufactured to produce a cubic shape upon inflation.

### Claim 15

A balloon kyphoplasty surgical device comprising:
an extrusion tube comprising at least two internal fluid channels and a support wire;
a port arrangement positioned on a proximal end of the extrusion tube in fluid communication with the at least two internal fluid channels; and
a balloon arrangement positioned on a distal end of the extrusion tube in fluid communication with the at least two internal fluid channels, the balloon arrangement resulting in a cubic shape when inflated thereby forming six flat surfaces,
wherein the balloon arrangement comprises a plurality of inner balloons housed within an outer balloon; wherein the inner balloons are configured to be in fluid communication with a single fluid channel and the outer balloon is configured to be in fluid communication with a single fluid channel thereby forming independently inflatable inner and outer balloons; wherein each inner balloon of the plurality of inner balloons is configured to be in fluid communication with a respective port/channel for each inner balloon.

### Claim 16 (depends on 15)

The balloon kyphoplasty surgical device of claim 15, wherein at least one inner balloon has a cylindrical shape.

### Claim 17 (depends on 15)

The balloon kyphoplasty surgical device of claim 15, wherein at least one inner balloon has a spherical shape.

### Claim 18 (depends on 15)

The balloon kyphoplasty surgical device of claim 15, wherein the plurality of inner balloons is at least four inner balloons.

### Claim 19 (depends on 15)

The balloon kyphoplasty surgical device of claim 15, wherein the plurality of inner balloons is at least two inner balloons.

### Claim 20 (depends on 15)

The balloon kyphoplasty surgical device of claim 15, wherein each inner balloon of the plurality of balloons is configured to be in fluid communication with a respective port/channel for each inner balloon.
