Intralumenal material removal using an expandable cutting device

摘要: Intralumenal material removal systems are provided using an advanceable, rotatable and expandable cutter assembly. The intralumenal system includes a assembly positionable in the lumen of mammalian subject operably connected to controls. comprises distal cutting head adjustable that is axially advanceable by translating drive shaft rotating shaft. between smaller diameter condition larger condition. may thus be introduced withdrawn from site retracted, facilitates translation navigation device through various lumens. selectively expanded at facilitate cutting, aspiration occlusive material.
