Abstract
An apparatus for obtaining a pressure tight seal around the ostium of a blood vessel branch by clamping to the parent blood vessel or duct wall without deforming the branch. The apparatus may then be used for the injection of a hardenable material such as a polymerizable liquid plastic or a hardenable radiopaque liquid. When the blood vessel or duct is completely filled and the injected material has hardened, the original blood vessel or duct tissue can be removed by corrosion. An accurate replica of the blood vessel or duct is then obtained. The replica may be studied as part of a postmortem examination or used for instruction. If the radiopaque liquid has been used, the replica may be studied by the use of x-rays.
