Precannulated fenestration
View Patent ↗Devices for delivering and deploying an endoluminal prosthesis are disclosed and comprise a delivery catheter, an endoluminal prosthesis disposed at a distal end portion of the delivery catheter, and a wire. The prosthesis comprises a tubular graft having at least one fenestration. The wire extends distally from a first wire end through an axial lumen of the delivery catheter and the prosthesis, and through the fenestration in the graft. The wire extends proximally through a lumen of the prosthesis and through an axial lumen of the delivery catheter towards a second wire end. Additional devices, systems, and methods are disclosed.
1. A device for delivering and deploying an endoluminal prosthesis, the device comprising:
a delivery catheter having at least one axial lumen; and
an endoluminal prosthesis disposed at a distal end portion of the delivery catheter and comprising a tubular graft having a first opening at a first end, a second opening at a second end, and at least one fenestration in the graft between the first and second ends; and
a wire comprising first and second ends, each disposed at a proximal end portion of the delivery catheter, and a body portion disposed between the first and second ends of the wire; where the wire extends distally from the first wire end through an axial lumen of the delivery catheter and the prosthesis, and through the fenestration in the graft; and
where the wire extends proximally through a lumen of the prosthesis and through an axial lumen of the delivery catheter towards the second wire end.
2. The device of claim 1 , further comprising an auxiliary catheter slid ably disposed within an axial lumen of the delivery catheter over a first end portion of the wire.
3. The device of claim 2 , where the auxiliary catheter comprises an elongate sheath and an elongate dilator disposed within an axial lumen of the sheath.
4. The device of claim 2 , further comprising a second auxiliary catheter slidably disposed within an axial lumen of the delivery catheter over a second end portion of the wire.
5. The device of claim 4 , where the second auxiliary catheter comprises an elongate sheath and an elongate dilator disposed within an axial lumen of the sheath.
6. The device of claim 1 , where the prosthesis comprises two or more fenestrations in the graft.
7. The device of claim 1 comprising one or more attachment points between the prosthesis and the wire.
8. The device of claim 7 , where each of the attachment points comprises a suture.
9. The device of claim 7 , where the one or more attachment points attach the wire to an exterior surface of the prosthesis.
10. The device of claim 7 , where the wire is slid ably disposed through the fenestration.
11. The device of claim 1 , where the wire is slid ably disposed through the fenestration.
12. The device of claim 1 , further comprising any two or more of the following:
an auxiliary catheter slidably disposed within an axial lumen of the delivery catheter over a first end portion of the wire;
the auxiliary catheter comprises an elongate sheath and an elongate dilator disposed within an axial lumen of the sheath;
a second auxiliary catheter slidably disposed within an axial lumen of the delivery catheter over a second end portion of the wire;
the second auxiliary catheter comprises an elongate sheath and an elongate dilator disposed within an axial lumen of the sheath;
the prosthesis comprises two or more fenestrations in the graft;
one or more attachment points between the prosthesis and the wire;
each of the attachment points comprises a suture;
the one or more attachment points attach the wire to an exterior surface of the prosthesis; and
the wire is slidably disposed through the fenestration.
