Abstract
A tracheostomy dilator moulded from a plastics material is formed with an S shape having a flexible, tapered patient end region for insertion to the trachea. A handle region at the opposite end has a substantially constant diameter along its length. A passage along the dilator receives a guide member, the tip of the patient end of the dilator making a stepless transition with the surface of the guide member.
