Apparatus for replication of blood vessels and ductal organs

An apparatus for producing anatomically accurate and complete casts of blood vessels and ductal organs of animals from a hardenable material, said apparatus comprising:

• a lockable clamping means capable of encircling a selected blood vessel or ductal organ tissue, said clamping means including a pair of edge-mated, semi-circular segments of a split toroidal ring, each segment being mounted on a respective end of a leg of a first locking forceps to form a tissue encircling ring;
• a sealing means mounted on one leg of a second locking forceps, said forceps being rigidly joined to the first forceps such that the sealing means is movable orthogonally relative to the clamping means, said sealing means including an injection opening through which the hardenable material is fed to the tissue, said sealing means cooperating with the clamping means to confine a circumferential portion of the tissue around an opening of the tissue so as to provide a leak-tight entrance into said tissue;
• and
• injection means for feeding hardenable material to said sealing means.
