摘要:
An interventional catheter incorporates an advanceable, rotatable operating head having a fixed blade cutter assembly and an adjustable blade cutter assembly. Aspiration ports and/or infusion ports providing access to a sealed lumen and aspiration and infusion systems are provided on, or in proximity to, the operating head. A shearing device may be provided within an aspiration port to further reduce the size of unwanted material during removal from a body lumen. A drive shaft provides rotation and torque from a drive system to the cutter assemblies and shearing device, and may be coupled to the cutter assembly by means of an articulating bearing assembly.
