APPARATUS AND METHODS FOR STENT DELIVERY WITH EMBOLIC PROTECTION

摘要

The present invention relates to a catheter system of the type comprising : -a stent delivery catheter (2) having a proximal end and a distal end and an interior lumen extending between the proximal end and the distal end; -a stent (1) having a proximal end and a distal end and a stent lumen extending between the proximal end and the distal end, the stent having an expandedst ate and an unexpanded state; -and an embolic protection filter (3) having an expanded state and an unexpanded state; the catheter system having a deploy ed position and an undeployed position. According to the invention the cathe ter system is characterised in that when the catheter system is in the undep loyed position, the stent (1) is in its unexpanded state and positioned with in the interior lumen of the stent delivery catheter (2) and the embolic pro tection filter (3) is in its unexpanded state and positioned within the sten t lumen of the stent.
