Definitions

  • the sub-microcatheter of the present invention includes a unitary, flexible main body defining a lumen having a distal end and a proximal end.
  • a mandril is positionable within the sub-microcatheter and imparts to the main body flexibility and rigidity that is effective for optimizing trackability and steerability of the sub-microcatheter within vessels of a living being.
