Sheath for use with an ultrasound element
First Claim
1. An apparatus for delivering ultrasound energy and a drug solution to a treatment site within a patient'"'"'s vasculature, the apparatus comprising:
- an elongate, hollow sheath having a distal opening and an energy delivery section, wherein the sheath within the energy delivery section is at least partially constructed from a material that transmits ultrasound energy;
a drug delivery lumen positioned along at least a portion of the sheath, the drug delivery lumen having a series of drug delivery ports within the energy delivery section, the series of drug delivery ports configured to deliver drug solution to the treatment site;
an elongate body comprising an ultrasound element, the elongate body is movably positioned within the sheath, such that ultrasonic energy can be transmitted from the ultrasound element through the energy delivery section of the sheath; and
a cooling fluid lumen formed between the elongate body and the sheath by positioning the elongate body within the sheath.

Abstract
An apparatus for delivering ultrasound energy and a drug solution to a treatment site in a vessel is disclosed. The apparatus includes an elongate, hollow sheath having a distal opening and an energy delivery section at least partially constructed from a material that transmits ultrasound energy. The apparatus also includes a drug delivery lumen positioned along at least a portion of the sheath, the drug delivery lumen having at least one drug delivery port within the energy delivery section. The apparatus further includes an elongate body having an ultrasound element, the elongate body configured to be movably positioned within the sheath, such that ultrasonic energy can be transmitted from the ultrasound element through the energy delivery section.
