Abstract

Devices for efficient severing or cutting of a material or substance such as soft tissue suitable for use in open surgical and/or minimally invasive procedures are disclosed.-A cutting assembly generally includes a first (10OA) and second cutting blades (100) each having an inner surface and at least one set of cutting teeth, the first inner surface being in contact with the second inner surface so that the sets of cutting teeth of the first and second cutting blades are aligned with and configured to cooperate with each other when at least one of the cutting blades moves, e.g., rotates and/or oscillates, relative to the other. A tissue cutting device generally includes a probe and the cutting assembly configured to be in a storage configuration or in a cutting configuration. The cutting assembly may provide a coagulation mechanism.
