Abstract
A stent delivery device is disclosed that includes an inner tube having a distal portion which carries the stent on the delivery device. At least part of the inner tube is formed from a spirally wound wire. A movable outer tube is used to constrain the stent in a radially contracted state on the distal portion of the inner tube. A substantially straight elongate wire is configured inside the spirally wound wire and bonded at the distal and proximal portions of the wound wire. The outer tube may have at least one side port adjacent to the distal portion in communication with the annular space between the outer tube and the inner tube allowing radiopaque fluid to be injected through the annular space and out the side port in the vicinity of the stent.
