Abstract
A catheter includes a distal end, a proximal end, an outer tube extending from the distal end to the proximal end, and an inner tube extending through the outer tube. The distal end including a corrugated section attached to an end of the inner tube and an asymmetric balloon attached to the outer tube and configured to deflect the distal end of the catheter.
Claims32
A catheter comprising:
- a distal end;
- a proximal end;
- an outer tube extending from said distal end to said proximal end;
- and
- an inner tube extending through a length of said outer tube, said proximal end comprising an inflation port, an inner hub bonded to said outer tube and forming a seal therewith, and a flexible tube extending between said inflation port and said inner hub, said outer tube and said inner hub configured to rotate with respect to said inflation port.
A catheter comprising:
- a distal end;
- a proximal end;
- an outer tube extending from said distal end to said proximal end;
- and
- an inner tube extending through said outer tube, said distal end comprising a corrugated section attached to an end of said inner tube, and an asymmetric balloon attached to said outer tube and configured to deflect said distal end of said catheter.
A method for deflecting a catheter, the catheter including a distal end, a proximal end, an outer tube extending from the distal end to the proximal end, and an inner tube extending through the outer tube, the proximal end including an inflation port, a rotating hub bonded to the outer shaft, a flexible tube extending between the inflation port and the rotating hub, the outer tube and inner tube rotatable with respect to the inflation port, the distal end including a corrugated section attached to an end of the inner passage tube, and a deflection balloon attached to the outer tube and configured to expand more on one side than another side, said method comprising:
- providing a fluid at the inflation port;
- pressurizing the fluid such that it passes through the inflation port, through the flexible tube, into the rotating hub, into a space between the inner tube and the outer tube, and into the deflecting balloon;
- and
- causing the balloon to inflate until a desired deflection of the distal end is achieved.
