Catheter with vessel lining and methods for using same
Systems for providing access across a site of obstruction and methods for manufacturing and using such systems. Such systems may include a sleeve having an inflation lumen; a bushing disposed in a distal section of the sleeve; and an everting member coupled to the sleeve with the bushing, the everting member being movable from an inverted position inside the sleeve to an everted position outside the sleeve in response to an increase in pressure in the inflation lumen.
1. A method of opening an occlusion comprising:
advancing a guidewire through a sleeve with a balloon inverted within an inflation lumen of the sleeve;
gripping the guidewire with the balloon;
everting the balloon from the sleeve to distally advance the guidewire gripped by the balloon;
re-inverting the balloon into the sleeve to retract the guidewire gripped by the balloon; and
re-everting the balloon from the sleeve to distally advance the guidewire re-gripped by the balloon.
2. The method of claim 1 , wherein the step of gripping further comprises pressurizing the inflation lumen to inflate the balloon.
3. The method of claim 1 , wherein the step of everting includes advancing a push tube coupled to a distal end of the balloon within the sleeve.
4. The method of claim 3 , wherein the step of re-inverting includes pulling the push tube proximally relative to the sleeve to re-invert the balloon.
5. The method of claim 1 , wherein in the advancing step, the sleeve further comprises an anchoring member coupled to the sleeve, the anchoring member being in fluid communication with the inflation lumen and being expandable from a deflated position to an inflated position to anchor the sleeve near a site of obstruction when the inflation lumen is pressurized.
6. The method of claim 1 , further comprising repeatedly everting and inverting the balloon to cyclically advance and retract the guidewire.
7. The method of claim 1 , further comprising:
depressurizing the inflation lumen;
withdrawing the guidewire;
re-pressurizing the inflation lumen; and
everting the balloon from the sleeve to distally advance the balloon.
8. A method of opening an occlusion comprising:
advancing a guidewire through a sleeve and a balloon inverted into an inflation lumen of the sleeve;
gripping the guidewire with the balloon;
everting the balloon from the sleeve to distally advance the guidewire gripped by the balloon;
depressurizing the inflation lumen;
advancing the sleeve to re-invert the balloon into the inflation lumen;
re-pressurizing the balloon to re-grip the guidewire with the balloon; and
re-everting the balloon from the sleeve to distally advance the guidewire re-gripped by the balloon.
9. A method of opening an occlusion-comprising:
advancing a guidewire through a sleeve and a balloon inverted into an inflation lumen of the sleeve;
gripping the guidewire with the balloon;
everting the balloon from the sleeve by advancing a push tube coupled to a distal end of the balloon within the sleeve to distally advance the guidewire gripped by the balloon; and
re-inverting the balloon into the sleeve to retract the guidewire gripped by the balloon.
10. The method of claim 9 , wherein the step of gripping further comprises pressurizing the inflation lumen to inflate the balloon.
11. The method of claim 9 , wherein the step of re-inverting includes pulling the push tube proximally relative to the sleeve to re-invert the balloon.
12. The method of claim 9 , wherein in the advancing step, the sleeve further comprises an anchoring member coupled to the sleeve, the anchoring member being in fluid communication with the inflation lumen and being expandable from a deflated position to an inflated position to anchor the sleeve near a site of obstruction when the inflation lumen is pressurized.
13. The method of claim 9 , further comprising repeatedly everting and inverting the balloon to cyclically advance and retract the guidewire.
14. The method of claim 9 , further comprising:
depressurizing the inflation lumen;
withdrawing the guidewire;
re-pressurizing the inflation lumen; and
everting the balloon from the sleeve to distally advance the balloon.
15. The method of claim 9 , further comprising:
depressurizing the inflation lumen;
advancing the sleeve to re-invert the balloon into the inflation lumen;
re-pressurizing the balloon to re-grip the guidewire with the balloon; and
re-everting the balloon from the sleeve to distally advance the guidewire re-gripped by the balloon.
