Percutaneous dilation tracheostomy device and method of using

A percutaneous dilation tracheostomy device comprising:

• a hollow casing having an elongate cylindrical proximal section and a curved tubular distal section;
• a plunger mechanism housed within the casing;
• a dilating mechanism positioned in the curved tubular distal section, mechanically coupled to the plunger mechanism, the dilating mechanism comprising a plurality of wall members positioned on an exterior surface of the curved tubular distal section;
• and
• a lumen running from a proximal end of the proximal section to a distal tip of the distal section, and
• wherein the plurality of wall members are configured to be expandable between a retracted configuration that positions each of the plurality of wall members flush against the exterior surface of the curved tubular distal section and an extended configuration that positions each of the plurality of wall members at an adjustable distance radially outward from the exterior surface of the curved tubular distal section.
