<p>A miniaturized brush (10) and method of making same having a hollow lumen for receiving a guide wire (22) and for introducing an agent for dissolving a soft fibrinous obstruction such as a recently formed thrombus, within a patient's vascular system. The brush (10) has soft, flexible bristles extending outward from the drive shaft (14) distal section, the bristles (28) being sufficiently resilient and dimensioned for enabling compression and passage of the brush (10) out of and back into the distal end of an introducer lumen and to mix into the fibrin of the soft thrombus, yet not damage the vessel wall. The brush (10) is formed of brush bristles entrapped between coiled wire (60) turns of a metal having enhanced radiographic imaging characteristics wound about the drive shaft (14) distal section.</p> |
