Abstract

Embodiments may include systems and methods for treating an occluded area in a body, accessing cavities or passages of the body, or reducing pathologic material in the body. Embodiments may be configured to apply vibratory energy to pathologic material in a treatment area of a body. A handle connected to an energy source may be configured to provide an energy signal. A transducer may be configured to receive the energy signal. An effector may be operatively coupled to the transducer. The effector may have a proximal end connected to the handle and a distal portion configured to apply vibratory energy to pathologic material. A cannula may have a longitudinal passage to receive at least a portion of the effector and/or be configured to expose at least the distal portion of the effector to the pathologic material or the treatment area.
