Patent ID: 7955345

Claim:
A method of using a medical device comprising: two microcatheter lumens, each lumen containing: a macrocoil thrombus engaging component having a length with a proximal end and a distal end, the length of the macrocoil comprised of microcoils that allow the length of the macrocoil to be extendable and flexible and which microcoils increase the flexibility and conformability of the macrocoil; a first wire capable of providing force on the distal end of the macrocoil; a second wire capable of providing force on the proximal end of the macrocoil; wherein for at least one macrocoil thrombus engaging coil: a microguidewire is passed through at least one of the lumens to help pass a microcatheter through a larger guiding catheter and to place the microcatheter distal to the thrombus, particularly passing between the clot and the vessel wall; removing the microguidewire; a macrocoil pull-string system comprising push-pull capability is passed through the at least one of the lumens of the microcatheter(s); the macrocoil pull-string system is passed distal to the clot; the macrocoil pull-string system is used to form an at least partially enclosing distal meshwork on the distal surface of the thrombus; macrocoils are extended from the microcatheter as it is partially withdrawn, passively encircling around the clot as a meshwork with exterior surfaces of the macrocoils contacting the clot; progressively pulling on the pull string so that the meshwork becomes more tightly engaged with the clot and conforms more to a shape of the clot.
