ABSTRACT:
A surgical device employs a catheter for removing obstructive material from the body cavity or lumenal passage. The catheter has a blade subassembly on its distal tip for coring, homogenizing, diluting, and aspirating the obstructive material. The obstructive material is homogenized and diluted after it is cored but prior to its aspiration into the catheter. Homogenization and dilution of cored obstructive material is shown to enhance the reliability of the surgical protocol by helping to prevent clogging of the catheter during aspiration.
