    摘要： An ablation system comprises a tool including an shaft having proximal and distal end portions, a handle at the proximal end portion, and a lumen extending between the proximal and distal end portions. The system further includes an ablation subsystem comprised of an ablation element at the distal end portion of the shaft, and an ablation source connected to the ablation element. The system further includes an imaging subsystem comprising an ultrasound imaging transducer disposed proximate the ablation element. The transducer is pivotally attached to the shaft or the ablation element to allow the transducer to articulate between stowed and deployed positions. The imaging subsystem further comprises a processor connected to the transducer configured to receive image data acquired by the transducer, and to generate an image corresponding thereto. The imaging subsystem still further includes a display connected to the processor configured to display the generated image.

    摘要： A deflectable, flexible device includes an elongate body, a convoluted tip portion at a distal end of the elongate body, and a lumen to receive one or more wires. The convoluted tip portion includes an electroformed pleated region which is formed by electrodepositing a metal on a mandrel having a pleated region. The convoluted tip portion may be hermetically sealed to permit repeated sterilization. The electroformed pleated region may include one or more fluid emission orifices. The convoluted tip portion extends or bends in response to fluid pressure manipulation, contact with tissue, manipulation with an internal spring or wire, or by a user pushing, pulling, or twisting the catheter directly or via an introducer sheath or the like. The convoluted tip portion may further include an RF ablation element or other energy-driven technique to create continuous linear lesions or a sensing element.

    摘要： A tissue ablation system facilitates lesioning deep tissue while preventing damage to superficial tissue and includes a probe having a distal end portion, at least one transducer carried on the distal end portion, and at least one acoustically transparent heat removal element thermally coupled to a target tissue within the beam path of the transducer. The transducer delivers acoustic energy to the tissue through the heat removal element in order to ablate the tissue; the heat removal element removes sufficient thermal energy from the tissue volume to prevent thermal necrosis in superficial tissue. The heat removal element may be a heat sink or a convective element. An optional temperature sensor provides advisory data to a practitioner and/or is coupled to a feedback control system operable to control delivery of acoustic energy to the tissue and/or a rate of thermal energy removal therefrom.

    摘要： A system for ablating tissue includes a catheter having an elongate body, with at least one ablation element (e.g., RF electrode) and at least one acoustic transducer located within the body's tip region. The transducer receives acoustic signals from proximate the tip region. The system also includes a monitoring unit coupled to the transducer to interpret the received acoustic signals as data regarding at least one therapeutic parameter (e.g., pre-pop detection, lesion making progress, tissue interface detection, tissue contact force, tissue contact establishment, bubble spatial distribution, bubble depth, bubble size, bubble size distribution, tissue interface distance, tissue interface position, tissue attenuation, tissue thickness, lesion spectral fingerprint). The monitoring unit is operable to provide feedback to a practitioner, such as graphical, audible, and/or haptic output of sensed data, and may also be operable to control operation of the at least one ablation element in response thereto.
