Abstract
An ultrasonic surgical device for performing a surgical procedure includes an elongated member having a proximal end and a distal end spaced along a longitudinal axis. The elongated member has an inner surface and an outer surface. The inner surface defines a passageway. A septum is configured to separate the passageway into a first conduit and a second conduit. A distal end of the second conduit terminates before a distal end of the first conduit to form a stepped configuration. An ultrasonic-driven cutting blade is disposed within the second conduit and is configured for cutting tissue such that the cutting blade vibrates ultrasonically to cut tissue. The distal end of the first conduit includes an outlet configured for delivering material to a surgical site and the distal end of the second conduit includes an inlet configured for aspirating the surgical site.
