Devices, systems, and methods for endovascular staple and/or prosthesis delivery and implantation
Devices, systems, and methods for implanting expandable prostheses in the body lumens rely on stapling or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a stapling system is introduced within the expanded prosthesis to deploy a plurality of fasteners to at least one prosthesis end. The stapling system may apply a force to the prosthesis to modify the shape of the prosthesis to conform to the shape of the vessel wall. The stapling system can be deflected in one or more distinct steerable segments. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.
1. A steerable guide catheter comprising:
one and only one guide tube having a length and defining an open interior lumen, the lumen adapted for accommodating passage of an operative endovascular tool, the one guide tube comprising a first steerable segment and a second steerable segment at a distal end region of the one guide tube, and an integrated handle assembly comprising: a first rotational deflector knob coupled to the first steerable segment of the one guide tube to apply a deflecting force to bend the first steerable segment of the one guide tube, the first rotational deflector knob adapted to bend the first steerable segment in a first articulated position, and a second rotational deflector knob coupled to the second steerable segment of the guide tube to apply a deflecting force to bend the second steerable segment of the one guide tube, the second rotational deflector knob adapted to bend the second steerable segment in a second articulated position, the lumen extending through the first rotational deflector knob and the second rotational deflector knob.
2. A steerable guide catheter according to claim 1 :
wherein the second articulated position is different than the first articulated position.
3. A steerable guide catheter according to claim 1 :
further including an operative tool that applies one or more fasteners to tissue.
4. The steerable guide catheter of claim 1 wherein the first rotational deflector knob and the second rotational deflector knob are located at opposite ends of the integrated handle assembly.
5. The steerable guide catheter of claim 4 wherein the integrated handle assembly further comprises a control handle between the first rotational deflector knob and the second rotational deflector knob.
6. The steerable guide catheter of claim 1 further comprising:
a first deflecting means directly coupling the first rotational deflector knob to the first steerable segment; and
a second deflecting means directly coupling the second rotational deflector knob to the second steerable segment.
7. The steerable guide catheter of claim 6 wherein the first deflecting means and the second deflecting means are selected from the group consisting of steering wires and pull cords.
