What is "bioptome"

n. A pincer-shaped cutting and grasping instrument used in medicine for taking biopsy specimens.

A bioptome is a small pincer-shaped cutting/grasping instrument used in medicine for taking biopsy specimens. It can either be built into or threaded through a vascular catheter or endotracheal tube that delivers the bioptome directly to the desired site of tissue sample (in this case, probably the inner walls of the heart or gastrointestinal tract).
