Apparatus and methods for transferring ultrasonic energy to a bodily tissue

摘要

An apparatus includes a monolithically-constructed transmission member that defines a lumen along a longitudinal axis. The transmission member includes a first portion, a second portion, and a third portion. The first portion is configured to be coupled to an ultrasonic energy source. The second portion is configured to contact a bodily tissue to transfer ultrasonic energy from a first portion into the bodily tissue. The third portion is disposed between the first portion and the second portion and defines a cross-sectional 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 moment of inertia of the second portion.

主权项

1. An apparatus, comprising:
a transmission member configured to transfer ultrasonic energy from a first end portion to a second end portion, the transmission member defining a lumen along a longitudinal axis of the transmission member, a sidewall of the transmission member defining an elongated opening therethrough in fluid communication with the lumen; and an outer member fixedly coupled to the transmission member via an adhesive, a portion of the outer member disposed about the elongated opening such that the lumen is fluidically isolated from a region outside of the outer member.
