Abstract

A sampling device and method of retrieving a sample are disclosed. The device includes a cannula having a first end and a second end. The first end has a threaded section. The method includes providing a stylet, providing a cannula having an axial channel, and inserting the stylet into the axial channel. Then, the stylet is connected to the cannula to form an assembly, and the assembly is inserted into a body to place an end of the cannula proximate to a sample location. Next, the stylet is disconnected, and the cannula is twisted to engage an end of the cannula in a part of the body. The stylet is removed from the axial channel, and a core collector is inserted in place of the stylet. Once the core collector is connected to the cannula, the cannula is twisted to further engage the end of the cannula in the part of the body, and to embed a portion of the core collector in the part of the body, so that a sample to be retrieved resides in the core collector. Then, the core collector is disconnected from the cannula, and removed from the cannula.
