A biopsy device is provided comprising a tubular member, a hollow shaft and an elongated fiber body. The hollow shaft may have a distal end and a shaft, wherein a laterally (sidewardly) facing notch is formed in the distal portion of the shaft. The elongated fiber body may include at least one optical fiber, preferably at least two optical fibers, with a distal end. The tubular member is movable relative to the shaft, between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member. The fiber body is movable within the shaft, between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.

System with photonic biopsy device for obtaining pathological information

The present invention relates to a medical probe which consists of a cannula with a multilumen stylet inside. The multilumen contains at least two lumen. Both the multilumen as well as the cannula may have beveled ends. In the lumen straight optical fibers (i.e. no angle end face) are present that can be connected at the proximal end to a console. The cannula, multilumen, fiber system forming the medical probe comprises at least in one of the lumen of the multilumen more than one optical fiber. Preferably the source and detector fibers for the fluorescence detection are contained in one single lumen of the multilumen.

Medical probe with multi-fiber lumen

A biopsy device includes a tubular member, a hollow shaft and an elongated fiber body having at least one optical fiber. The hollow shaft has a laterally (sidewardly) facing notch in its distal portion. The tubular member is movable relative to the shaft, between a first position in which the notch is covered by the tubular member, and a second position in which the notch is not covered by the tubular member. The shaft is movable between a first position in which the distal end of the optical fiber is located at the distal end of the shaft with the elongated fiber body extending through the notch, and a second position in which the distal end of the at least one optical fiber is located proximally to the notch.

The present invention relates to a medical needle which comprises an elongate tube and at least one optical fiber, e.g. two fibers, arranged within the elongate tube, for making optical measurements at the distal end of the needle. The optical fibers(s) has a beveled distal end surface, wherein a plane touching the beveled distal end surface and a longitudinal extension axis of the optical fiber forms a bevel angle which is 30&#xb0;-35&#xb0;. Such needle is advantageous for providing a medical needle which is reliable and long term stable, can be manufactured in low cost using known optical fiber materials, thus allowing it to form part of disposable medical kits. Still, the bevel angle of 30&#xb0;-35&#xb0; provides a needle which is easy to insert and which provides a low tendency to cause tissue sticking. Especially, the elongate tube and the optical fiber end(s) have the same beveled angle within the range 30&#xb0;-35&#xb0;, thus allowing a smooth front surface of the needle.
