Abstract
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.
Claims15
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.
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.
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.
