The gradual dilator includes a white plastic cylindrical tube prolonged by a curved section for intra cervical insertion.
The curved section is made of 4 or 5 segments (depending on the model), each being 1.5 cm long, and with increasing diameters as of the distal extremity.
Each segment fits over the truncated end of the previous one to avoid sharp edges.
The dilator’s distal extremity is rounded.
The proximal end includes a flat section to determine the direction of its curved section.
