Abstract

Systems, methods and apparatus (2) for removing arteriosclerotic plaque or clots, such as emboli and/or thrombi, from the interior of a fluid vessel, such as a cerebral or coronary artery, are provided. A coil capture device (4) includes a super-elastic coil (26) capable of percutaneously removing plaque and clots from blood vessels without the need for surgical intervention. A radiopaque element (38) is secured over the coil to improve visualization of the coil capture device (4), which enhances the accuracy of the procedure. A hollow introducing sheath (12) is also provided to facilitate the endo-luminal delivery of the coil capture device (4) to the clot region within the patient's vasculature.
