Hypotube. Seamless, hollow, stainless-steel tube cut to length and curved at one end. It is gold-plated at one end to ensure conductivity and corrosion resistance. It is an essential component of a medical device used for endovascular treatment of intracranial aneurysms. A pulse runs through the hypotube, melts a micro-polymer joint and detaches a coil that occludes the aneurysm. A longitudinal slot on the gold-plated end of the hypotube allows for a green lead wire to exit mid-shaft while a yellow wire runs full length, forming the pulse path. This slot allows the wires to interface with a handheld controller at different locations. The outer diameter profile of the hypotube has different sizes in the distal, mid and proximal positions. It is supplied non-sterile and ends protected with heat-shrink.
