Abstract
An in-situ fenestration device. The device includes a sheath, a sonic catheter extending with the sheath and having a cutting tool at a distal section thereof, and a balloon catheter extending within the sonic catheter. The cutting tool of the sonic catheter is configured to cut a fenestration in a graft material at a fenestration site of a stent graft upon being energized with ultrasonic energy at a cutting frequency.

An in-situ fenestration device comprising:
- a sheath;
- a sonic catheter extending with the sheath and having a cutting tool at a distal section thereof;
- and
- a balloon catheter extending within the sonic catheter,
- the cutting tool of the sonic catheter configured to cut a fenestration in a graft material at a fenestration site of a stent graft upon being energized with ultrasonic energy at a cutting frequency.
An in-situ fenestration device comprising:
- a sheath;
- a sonic catheter extending with the sheath and having a cutting tool at a distal section thereof;
- a balloon catheter extending within the sonic catheter;
- and
- a locating device carried on a distal end of a guidewire and configured to locate the fenestration site, and
- the cutting tool of the sonic catheter configured to cut a fenestration in a graft material at the fenestration site of a stent graft upon being energized with ultrasonic energy at a cutting frequency.
A method of forming a fenestration in a graft material at a fenestration site of a stent graft, the method comprising:
- delivering a balloon of a balloon catheter to the fenestration site;
- locating a sonic cutting tool on a distal end of a sonic catheter at the fenestration site by inflating the balloon;
- and
- energizing the sonic cutting tool with ultrasonic energy at a cutting frequency to cut the fenestration in the graft material at the fenestration site of the stent graft.
