Abstract: A biopsy device with a hollow shaft is suggested, the shaft having a wall and a distal end portion, wherein a sidewardly facing notch is formed in the distal end portion. At least two optical fibers are arranged in the wall of the shaft so that end surfaces of the fibers are arranged in a longitudinal direction at opposite positions with respect to the notch.

Abstract: An interventional device, e.g. a Vacuum Assisted Biopsy (VAB) needle, incorporating optical fibers such that biological tissue in a volume at a side of the interventional device can be substantially completely optically probed by optical spectroscopy. In a VAB embodiment, a plurality of optical fiber pairs connected to respective optical ports, are placed at opposite positions along the suction cavity, and they are readout subsequently allowing to make a map of the tissue properties along the place where the tissue will be cut by the VAB needle. Based on decision software in an optical console, it can be determined whether the tissue present in the cutting cavity is completely normal tissue or not, prior to actually performing the biopsy on the tissue. In this way a well defined end point for VAB is created. In one embodiment, the optical fibers are arranged in a wall structure of a thin sleeve which fits onto existing VAB needles, thus allowing the VAB needle to be upgraded with an optical probing capability.
