Abstract:
A flexible bag adapted to pass through a catheter lumen and expand to substantially occupy a fluid-filled cavity larger than said lumen, said bag being adapted to receive fluid within said cavity and a clotting medium for contact with said fluid, said bag comprising a plurality of interlaced flexible filamentary members, said filamentary members being spaced apart to form a multiplicity of pores, said pores being sized to allow said fluid to enter said bag but prevent outward extension of said clotting medium, said filamentary members being resiliently biased to expand said bag to a first diameter substantially filling said cavity upon release from said catheter lumen, said filamentary members being resiliently deformable to allow for contraction of said bag to a second diameter smaller than said first diameter, said bag being sized to slidingly interfit within said catheter lumen when contracted to said second diameter.
