PROBLEM TO BE SOLVED: To provide a catheter for optical biopsy, especially of pulmonary tissue, considerably reducing costs of the intervention.SOLUTION: A catheter for optical biopsy comprises: a forceps for tissue sampling on its distal end; and a forceps control device, a light source, and a device for imaging and analysis of a scanned tissue on its proximal end, with the distal and proximal ends interconnected with an elongated sheath 4 containing at least one optical fiber 5 and a Bowden cable with a control cable or a wire. The sheath 4, made of flexible plastic, provides a lengthwise channel for the Bowden cable 3 placement, whereas the channel is open with a fissure 7 along the full length of the sheath 4.SELECTED DRAWING: Figure 5 |
