Rotating fiberoptic laser catheter assembly with eccentric lumen

摘要: The present invention provides for the ablation of obstructions in vessels such as arteries. A catheter having an optical fiber is used to transmit laser energy distal end fiber. housed a lumen within so that it eccentric with and also encompasses center core catheter. second houses steerable guide wire. substantially aligned This assembly operated by using wire advance obstruction, turning on, then rotating from which emitted ablates area larger diameter than allows narrow be cleared only minimal chance perforating vessel walls.
