A device for removing excrescences and polyps in a body cavity, has a resilient wire loop for fitting around the excresence or polyp, at the distal end of a tubular guide and connectible to a voltage source, the loop being movable by a proximal handle between a position in which the loop is retracted in the guide and an expanded position in which two opposed sides thereof terminate in a distal bulge, one of the sides of the loop having an inwardly kinked proximal portion in front of the distal end of the guide and the other side of the loop having at least two outwardly pointing kinks.
