Claim:
1. An apparatus, comprising: a monolithically-constructed transmission member defining a lumen along a longitudinal axis of the transmission member, the transmission member including a first portion, a second portion, and a third portion, the first portion configured to be coupled to an ultrasonic energy source, the second portion including a distal tip configured to be disposed within a body, the distal tip configured to move in response to an ultrasonic energy produced by the ultrasonic energy source to transfer the ultrasonic energy from the first portion through the second portion and into a bodily tissue, the third portion disposed between the first portion and the second portion, the second portion defining a distal end opening in fluid communication with the lumen, the first portion and the second portion having a constant outer diameter, the third portion defining a cross-sectional area moment of inertia that is less than at least one of a cross-sectional area moment of inertia of the first portion or a cross-sectional area moment of inertia of the second portion, a sidewall of the third portion of the transmission member defining an elongated opening therethrough in fluid communication with the lumen, the elongated opening having a depth at least half as large as an outer diameter of the first portion of the transmission member; and an outer member fixedly coupled to the transmission member about the elongated opening.
