Abstract:
A stent delivery device comprising:a sheath-catheter for delivery of a contrast medium, the sheath-catheter including a distal end and ports located proximally from the sheath-catheter's distal end;a stent delivery catheter slidably received in the sheath-catheter, the stent delivery catheter having a shaped stent holder;a distal vent, wherein the distal end of the sheath-catheter and the shaped stent holder cooperate to form the distal vent when the stent delivery catheter is deployed from the sheath-catheter;the ports and the distal vent functioning to direct contrast medium towards a lesion, wherein the contrast medium flows from the ports when the delivery catheter is retracted within the sheath-catheter, and the contrast medium flows through both the ports and the distal vent with substantially more fluid flowing through the vent when the stent delivery catheter is deployed.
