Abstract

In some embodiments, a sheath assembly may include a deformable sheath disposable around an ultrasonic probe including a curved section. The deformable sheath can include a deformable section configured to deform according to the curved section of the ultrasonic probe. The sheath assembly further includes one or more rigid sections coupleable to the deformable sheath, the one or more rigid sections configured to maintain a separation between the ultrasonic probe and the one or more rigid sections to reduce transfer of ultrasonic vibrations generated by the ultrasonic probe through the one or more rigid sections to a user grasping the one or more rigid sections.
