Novel aspiration catheter design for acute stroke thrombectomy.

Background: Navigable, large diameter aspiration catheters demonstrate markedly improved recanalization rates over smaller lumen devices in suction embolectomy. We evaluated the performance of a novel aspiration catheter system designed to maximize lumen size, and compare it to other commercially available aspiration catheters.

Methods: The 6F RQ aspiration catheter system comprises a proximal pusher wire of 117 cm length connected to a distal catheter of 25 cm length.

Drug-eluting tibial stents: objective patency determination.

Purpose: Endovascular management of limb-threatening ischemia often requires treatment of tibial occlusive disease. This study was preformed to examine the patency of drug-eluting tibial stents.

Materials And Methods: The medical records of all patients undergoing drug-eluting tibial stent placement for limb-threatening ischemia from June 2004 to June 2008 were retrospectively reviewed.
