Abstract

An apparatus for elevating tissue within a body, including a tubular member having a proximal end and a distal end and a central axis defined therethrough, in which the tubular member comprises a first lumen and a second lumen, separately formed therein, a balloon secured to a region of the tubular member, in which a region of the tubular member is engagable with an injection mechanism, in which the engaged injection mechanism is engagable to be in communication with the first lumen of the tubular member, and in which the first lumen of the tubular member provides a path to an interior of the balloon.

Claims

1. A method of elevating tissue within a body, comprising:

providing a tubular member having a proximal end and a distal end and a central axis defined therethrough, the tubular member comprising a first lumen and a second lumen, separately formed therein, the first lumen having a distal opening at its distal end, the distal end of the first lumen located at the distal end of the tubular member, the second lumen comprising a distal stop formed on a first region of the tubular member proximate the distal end,

wherein a balloon having an interior and a single opening to the interior is secured to a second region of the tubular member, the second region of the tubular member at or near the distal end of the tubular member, the distal end of the tubular member located within the interior of the balloon, wherein an injection mechanism is engaged to a third region of the tubular member and configured to inflate the balloon, wherein the first lumen provides a path for communication between the injection mechanism and the interior of the balloon wherein a guide wire is configured to engage with the tubular member, wherein the guide wire is configured to manipulate the tubular member from within the second lumen;

inserting a guide wire into the second lumen from the proximal end to the distal stop;

inserting the distal end of the tubular member into a joint, wherein the balloon is disposed, at least partially, within the joint; and

inflating the balloon within the joint, causing a tissue to elevate relative to a position of the tissue prior to inserting the balloon into the joint.

2. The method of claim 1, further comprising manipulating the tubular member within the joint.

3. The method of claim 1, wherein inflating the balloon within the joint comprises injecting a fluid into the balloon.

4. The method of claim 1, wherein inflating the balloon causes a capsule tissue to elevate from a femoral neck relative to a position of the capsule tissue prior to inserting the balloon into the joint.

5. The method of claim 1, further comprising deflating the balloon within the joint.

6. The method of claim 1, further comprising removing the tubular member from the joint.

7. The method of claim 1, further comprising providing a sheath disposed around the balloon and removing the sheath once the balloon is disposed, at least partially, within the joint.

8. The method of claim 7, further comprising moving the sheath along the tubular member in a direction that is parallel with the central axis of the tubular member, wherein the balloon is exposed from the sheath.

9. A method of elevating tissue within a body, comprising:

inserting a distal portion of a tubular member and a balloon secured to the distal portion of the tubular member into a joint;

inflating the balloon within the joint via a first lumen formed within the tubular member, the first lumen extending into the balloon; and

inserting a guide wire into a second lumen formed within the tubular member separately from the first lumen, the second lumen comprising a distal stop proximate a distal end of the tubular member, wherein the guide wire is inserted from a proximal end of the second lumen to the distal step.

10. The method of 9, further comprising manipulating the tubular member within the joint.

11. The method of 9, wherein inflating the balloon within the joint comprises injecting a fluid into the balloon.

12. The method of 9, wherein inflating the balloon causes a capsule tissue to elevate from a femoral neck relative to a position of the capsule tissue prior to inserting the balloon into the joint.

13. The method of 9, further comprising deflating the balloon within the joint.

14. The method of 9, further comprising removing the tubular member from the joint.

15. The method of 9, further comprising providing a sheath disposed around the balloon and removing the sheath once the balloon is disposed, at least partially, within the joint.

16. The method of 15, further comprising moving the sheath along the tubular member in a direction that is parallel with the central axis of the tubular member, wherein the balloon is exposed from the sheath.
