Abstract
Devices, processes and systems facilitate and enable treatment of acute stroke conditions, providing reperfusion while therapy is made available by preserving structure in the arterial tree. Using a Rapid Exchange approach with at least dual lumens in a microcatheter facilitates embolus/clot removal without damaging sensitive vasculature.
Claims13
A process for reperfusion during embolus removal comprising;
- providing a rapid exchange system comprising at least two lumens, a microcatheter, and a stroke device;
- accessing a desired treatment site within a blood vessel in the brain;
- emplacing the stroke device at the desired treatment site;
- establishing reperfusion of the blood vessel while maintaining a connection to the stroke device;
- maintaining arterial access including greater support to the arterial tree;
- and,
- addressing at least one of a subject embolus, blood clot, and thrombus while reperfusion continues.
4 more elements
A process for making a neuro-monorail microcatheter comprising:
- providing a first microcatheter;
- cutting a distal segment at between about 5 cm and 50 cm;
- aligning the distal segment adjacent to a distal section of a second microcatheter;
- placing guidewires in each microcatheter to maintain alignment;
- and
- applying short segments of PET along the length to secure and maintain alignment and adjacent status of the finish device.
3 more elements
A reperfusion device, comprising, in combination:
- a rapid exchange system comprising a first lumen and a second lumen;
- a microcatheter disposed within the first lumen, comprising a stroke device, wherein the stroke device is expandable;
- and
- a guidewire disposed within the second lumen.
