Patent ID: 8172871

Claim:
A closure device for closing a puncture wound, said device deliverable in a delivery sheath, said puncture wound having a length along a tissue tract that resolves in an interior opening of a vessel or cavity, said closure device comprising: (a) a distal section for placing inside said interior opening of said vessel or cavity, said distal section lodged in a delivery sheath having proximal and distal ends, said delivery sheath capable of penetrating said wound along said length of said wound to pass through said interior opening and release said distal section, said released distal section capable of rotation of about 90 degrees to provide resistance against said interior opening, (b) a middle section connected to said distal section so that upon rotation of said distal section, said middle section exterior to said vessel or cavity, remaining in connection with said distal section, (c) a proximal section connected to said middle section, said proximal section comprising a bunchable material capable of bunching in said tissue tract upon deployment, said proximal section also released from said delivery sheath in an unbunched state, bunchable upon release, (d) a first tension member connected to said distal section for rotating said distal section 90 degrees inside said vessel or cavity and placing said distal section inside said interior opening of said vessel or cavity to provide resistance against said interior opening, and (e) a second tension member connected to said proximal section for bunching said bunchable material of said proximal section within said tissue tract, thereby closing said puncture wound, and (f) a plunger lodged within said delivery sheath for rotating said distal section 90 degrees in coordination with said first tension member by pushing said plunger towards said distal section and pulling said first tension member against the pushing of said plunger, thereby closing said puncture wound with said distal section rotated 90 degrees inside said vessel or cavity and said proximal section bunched in said tissue tract.
