ATHERECTOMY DEVICE HAVING TRAPPING AND EXCISING MEANS FOR REMOVAL OF PLAQUE FROM THE AORTA AND OTHER ARTERIES |
摘要 |
An arterial catheter system for removing plaque from the aorta and other arteries is disclosed. The system typically includes an elongate catheter member, a filtration apparatus disposed within the distal region, and an atherectomy assembly which includes a mechanism for trapping and holding mobile or fixed plaque and an excising mechanism for removing the plaque. In use, the catheter is positioned so that the atherectomy assembly lies within a region of interest, the filtration apparatus is deployed downstream of the region of interest, the plaque is trapped and held by a snare, vacuum, or other trapping means, and then the excising mechanism is activated to remove the plaque. Methods are also disclosed for removing plaque from the aorta and other arteries. |
