Abstract

The present invention relates to a diathermy tunnelling catheter device (1). The device (1) has a remotely radially expandable basket (4) with a diathermic cutting and coagulating tip (2) and a plurality of spaced apart diathermic cutting and coagulating bars (3) extending rearwardly from said tip (2). In use the basket (4) is initially advanced into a growth in a radially contracted condition by diathermic cutting with said basket tip (2), the basket (4) is then radially expanded whilst radially cutting diathermically with the cutting bars (3) into the growth, and the basket (4) is then rotated whilst annularly cutting diathermically with the cutting bars (3). Conveniently the device (1) is used via the biopsy channel of an endoscope.
