  • Publication number: 20250128031
    Abstract: A method may include accessing an artery in communication with an ophthalmic artery of a subject, and advancing a microcatheter along the accessed artery so as to align a distal end of the microcatheter with an ostium of the ophthalmic artery, wherein the microcatheter includes a lumen having a guidewire positioned therein. In addition, the method includes proximally withdrawing the guidewire relative to the microcatheter so as to enable a distal portion of the microcatheter to assume a curved relaxed configuration, and cannulating the ostium with the distal portion of the microcatheter when the distal portion is in the curved relaxed configuration.

  • Patent number: 7942661
    Abstract: A balloon folding system specifically configured to reduce a side branch balloon of a bifurcated balloon catheter assembly includes a die that defines at least one chamber for receipt of the sidebranch balloon, and at least one pin sized to fit into the chamber and reduce the balloon to a substantially flattened state. The system also may include a housing for the reduction and folding of a primary branch balloon. The system is configurable to fold and reduce both branches simultaneously or separately.
