Claims18
A catheter system for retrieving material from a biological vessel comprising an inner tube movable within an outer tube and a braided funnel-shaped sleeve attached to said inner tube and being configured for transitioning between a collapsed state when sequestered within said outer tube and an expanded state when advanced out of said outer tube, wherein a portion of a distal end of said braided funnel-shaped sleeve includes distally-extending leaflets formed by wires.
A method of retrieving material from a biological vessel comprising:
- (a) partially advancing a funnel-shaped sleeve out of a tube of a catheter positioned in the biological vessel so as to form a cone of a predetermined length within the biological vessel;
- (b) suctioning the material in the biological vessel into said cone;
- and
- (c) further advancing said funnel-shaped sleeve out of said tube and applying said suction to thereby trap the material within said funnel-shaped sleeve.
