System for delivery of intracranial stent

A system for treating an intracranial blood vessel, the system comprising:

• a guiding apparatus including:
• a first abutment extending from a proximal end to a distal end of the first abutment;
• a second abutment extending from a proximal end to a distal end of the second abutment, the proximal end of the second abutment being adjacent to the distal end of the first abutment;
• a first radiopaque region extending from a proximal end to a distal end of the first radiopaque region, the proximal end of the first radiopaque region being adjacent to the distal end of the second abutment;
• a radiolucent region extending from a proximal end to a distal end of the radiolucent region, the proximal end of the radiolucent region being adjacent to the distal end of the first radiopaque region;
• and
• a second radiopaque region extending from a proximal end to a distal end of the second radiopaque region, the proximal end of the second radiopaque region being adjacent to the distal end of the radiolucent region.

A method of treating an intracranial atherosclerotic stenosis in an intracranial blood vessel, the method comprising:

• placing an intracranial stent on a guidance region of a guiding apparatus, the intracranial stent having a central portion disposed between a proximal end portion of the intracranial stent and a distal end portion of the intracranial stent, the central portion having a smaller diameter than the proximal end portion and smaller than the distal end portion of the intracranial stent when the intracranial stent is in an expanded configuration, the intracranial stent being in a compressed configuration when placed on the guidance region such that:
• a first radiopaque region of the guidance region is overlaid by the proximal end portion of the intracranial stent;
• a second radiopaque region of the guidance region is overlaid by the distal end portion of the intracranial stent;
• and
• a radiolucent region of the guidance region is overlaid by the central portion of the intracranial stent;
• and
• inserting the guidance region of the guiding apparatus in the intracranial blood vessel such that central portion of the intracranial stent corresponds to a location of the stenosis.
