Abstract

Apparatus for deploying an expandable structure in interior body regions provide an outer catheter tube, an inner catheter tube sized and configured to be received within the outer catheter tube, and an expandable structure having a distal end and a proximal end. The expandable structure also has a first end region adjacent the distal end and a second end region adjacent the proximal end. The distal end is bonded to the inner catheter tube to form a first bonded region and the proximal end is bonded to the outer catheter tube to form a second bonded region. The first end region is inverted to overlie the first bonded region and the second end region is inverted to overlie the second bonded region.

Claims

1. A device for deployment into an interior body region comprising

an outer catheter tube,

an inner catheter tube sized and configured to be received within the outer catheter tube, and

an expandable structure having a distal end, a first end region adjacent the distal end, a proximal end, and a second end region adjacent the proximal end, the distal end being bonded to the inner catheter tube to form a first bonded region and the proximal end being bonded to the outer catheter tube to form a second bonded region, the first end region being inverted to overlie the first bonded region and the second end region being inverted to overlie the second bonded region.

2. A device as in claim 1

wherein inversion of the distal end of the expandable structure creates a double-jointed distal end region.

3. A device as in claim 1

wherein inversion of the proximal end of the expandable structure creates a double-jointed proximal end region.

4. A device as in claim 1

wherein the proximal and distal ends of the expandable structure are bonded by an adhesive bonding process.

5. A device as in claim 1

wherein the proximal and distal ends of the expandable structure are bonded by a melt bonding process.

6. A device as in claim 1

wherein no portion of the inner catheter tube protrudes beyond the expandable structure.

7. A device as in claim 1

wherein the expandable structure provides a maximum diameter along essentially its entire length.

8. A method for manufacturing a device for deployment into an interior body region comprising

providing an outer catheter tube having a distal end and an inner catheter tube, the inner catheter tube being slidable within the outer catheter tube,

providing an expandable structure having a distal end, a first end region adjacent the distal end, a proximal end, and a second end region adjacent the proximal end,

inserting the inner catheter tube into the outer catheter tube,

moving the inner catheter tube a first distance beyond the distal end of the outer catheter tube,

bonding the distal end of the expandable structure to the inner catheter tube to form a first bonded region,

bonding the proximal end of the expandable structure to the outer catheter tube to form a second bonded region,

moving the inner catheter a second distance beyond the distal end of the outer catheter tube, the second distance being a lesser distance beyond the distal end of the outer catheter tube than the first distance, to invert the first and second end regions such that the first and second end regions overlie the first and second bonded regions respectively, and

securing the relative position of the inner catheter tube and the outer catheter tube against further movement.

9. A method as in claim 8

wherein the proximal and distal ends of the expandable structure are bonded by an adhesive bonding process.

10. A method as in claim 8

wherein the proximal and distal ends of the expandable structure are bonded by a melt bonding process.

11. A method as in claim 8

wherein the relative position of the inner catheter tube and the outer catheter tube are secured against further movement by an adhesive process.
