Patent attributes
A vasculature navigation system may include a dilator having a proximal end and a distal end located opposite the proximal end, the dilator comprising a guidewire lumen extending between the proximal end and the distal end, the dilator defining a proximal portion and a distal portion located opposite the proximal portion. In some embodiments, the vasculature navigation system also includes an access port located at the proximal end of the dilator, a distal port located at the distal end of the dilator, and a hemostasis valve coupled to the proximal portion of the dilator. The hemostasis valve may be configured to control fluid flow between the proximal portion and the distal portion. In some embodiments, a flush port is coupled to the proximal portion of the dilator and located distal to the hemostasis valve, and the flush port is coupled to a fluid supply source.
