Ischemic stroke device

Apparatus for removal of at least a portion of an obstruction from an obstructed blood vessel for treatment of ischemic stroke, comprising:

• a telescoping support member including an outer tubular shaft and an inner elongate member extending through said outer tubular shaft and slidable within said outer tubular shaft, said outer tubular shaft having a distal end, and said inner elongate member having a distal end and a proximal end;
• a first expandable member having a proximal end and a distal end and a tubular body extending between the proximal and distal ends of the first expandable member, said proximal end of said first expandable member being attached to said distal end of said outer tubular shaft of said telescoping support member, and said distal end of said first expandable member being attached to a distal portion of said inner elongate member, said first expandable member having a radially compressed configuration and a radially expanded configuration, and said first expandable member having a longitudinally extended configuration with said proximal and distal ends of said first expandable member disposed at opposing ends of said first expandable member, and an everted configuration with said distal end of said first expandable member withdrawn within said tubular body of said first expandable member adjacent to said proximal end of said first expandable member;
• and
• a second expandable member configured to be deployed into an obstruction within the blood vessel, said second expandable member having a closed distal end and a closed proximal end, and a tubular mesh body extending between the proximal and distal ends of the second expandable member, said closed proximal end of said second expandable member being permanently joined to said distal end of said inner elongate member of said telescoping support member, said tubular mesh body being configured to radially expand into contact with at least a portion of the obstruction such that a portion of the obstruction is dislodged to enhance blood flow through the blood vessel, said tubular mesh body including a plurality of interstices, at least a portion of the interstices being adapted to allow passage of at least one dislodged portion of the obstruction therethrough in a radial direction into the tubular mesh body.
