Abstract
A lead for navigating small vessels and a catheter system for implantation of leads into small vessels. Veins that return blood to the heart against the force of gravity often have valves in them to prevent backflow of deoxygenated blood. Leads and catheter systems in accordance with embodiments of the invention allow cannulation and lead implantation in small, tortuous, obstructed, and difficult to access veins enabling a range of stimulation and sensing applications.
