Abstract

An apparatus for delivering acoustic energy to a target site adjacent a body passage includes first and second elongate members, each carrying one or more transducer elements on their distal ends. The first and/or second elongate members include connectors for securing the first and second elongate members together such that the transducer elements together define a transducer array. The first and second elongate members are introduced sequentially into a body passage until the transducer elements are disposed adjacent a target site. Acoustic energy is delivered from the transducer elements to the target site to treat tissue therein. In another embodiment, the apparatus includes a tubular member and an expandable structure carrying a plurality of transducer elements. The structure is expanded between a contracted configuration during delivery and an enlarged configuration when deployed for delivering acoustic energy to a target site adjacent the body passage.

Claims

1. An apparatus for delivering acoustic energy to a target site adjacent a body passage, comprising:

a first member comprising a proximal end, a distal end having a size and shape for insertion into a body passage, and a first transducer carried on the distal end; and

a second member comprising a proximal end, a distal having a size and shape for insertion into the body passage, and a second transducer carried on the distal end, the first and second transducers detachably coupled to each other to at least partially form a transducer array for delivering acoustic energy to a target site adjacent the body passage.
