Patent Images
1. A medical device comprising:
- a) an inner catheter having a proximal portion and a distal portion;
b) an outer catheter having a first lumen therethrough and a proximal portion and a distal portion, the outer catheter disposed around the inner catheter and forming an annular space between the distal portion of the outer catheter and the distal portion of the inner catheter;
c) a dilation balloon disposed around the distal portion of the outer catheter; and
d) a stent disposed in the annular space between the distal portion of the outer catheter and the distal portion of the inner catheter; and
e) a manifold havingi) a flushing port fluidly coupled to the annular space between the inner catheter and first lumen of the outer catheter, andii) an inflation port fluidly coupled to a second lumen in the outer catheter to permit inflation of the balloon.

Abstract
A balloon catheter with a stent delivery device having inner and outer catheters, with the outer catheter having a second lumen for inflation of the balloon. The delivery device also includes a radiopaque marker band adjacent each end of the stent located at the distal end of the device adjacent a tapered tip. The device also includes a manifold having a flushing port fluidly coupled to an annular space between the inner and outer catheters and an inflation port fluidly coupled to the second lumen of the outer catheter for inflating the balloon.

8. A stent delivery system comprising:
-
a) an inner catheter having a proximal portion and a distal portion, the inner catheter forming a lumen at least in its distal portion; b) an outer catheter disposed around the inner catheter and forming an annular space between the inner and outer catheters, the outer catheter having a dilation balloon disposed around a distal region thereof, and a lumen fluidly coupled to the interior of the dilation balloon; and c) a stent located at a distal region of the annular space between the inner and outer catheters, wherein the balloon is positioned radially outwardly of the stent and further wherein the balloon is inflatable for pre-stent-deployment dilation of a vessel containing the device. - View Dependent Claims (9, 10)
