摘要： An ablation catheter (10) includes a body (12) having a distal end (16), a hollow tip (22) attached to the distal end and an ultrasound transducer assembly positioned within the hollow tip and mounted to rotate about a longitudinal axis of the catheter body. The hollow tip includes an acoustically transparent shell, which allows acoustic energy to pass to and from the ultrasound transducer assembly, and an electrically-conductive coating on its exterior surface, which allows ablating energy to be delivered to an adjacent tissue. A plurality of ribs extend inwardly from an inner surface of the shell. A system (100) incorporating the ablation catheter and methods of using the same to ablate, image and/or monitor tissue are also disclosed.

摘要： Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.

摘要： An electrosurgical device is provided. The device includes a cooled probe, an introducer, and a side port for the introduction of liquid into a lumen defined by an outer diameter of the probe and an inner diameter of the introducer when the probe is positioned inside the introducer such that a distal end of the probe can contact a target site (e.g., the site near/adjacent the tissue to be treated). The side port can be connected to a syringe/other liquid introduction apparatus via tubing so that a liquid (e.g., a therapeutic agent, saline, etc.) can be injected into the lumen and can exit the distal region of the introducer so that it is delivered to the target site. Additionally, the syringe can be removed so that the tubing can serve as a vent during treatment with the electrosurgical device.

摘要： A balloon catheter device with a fluid management system includes a source of balloon fill media and a balloon catheter in fluid communication with the source of balloon fill media. A first conduit is provided for delivering the balloon fill media from the source to the balloon catheter for inflation of a balloon of the catheter device. A second conduit is provided for returning the balloon fill media from the balloon catheter to the source for deflating the balloon. A first pump is disposed along one of the first conduit and the second conduit for pumping the balloon fill media through the respective conduits. The fluid management system operates in three states, namely, (1) a first state in which the balloon fill media is delivered to the balloon for inflation thereof, (2) a second state in which the balloon fill media is removed from the balloon for deflation thereof; and (3) a trapped volume mode in which the balloon fill media is circulated through the balloon so as to maintain an at least substantially constant pressure in the balloon. The fluid management system is configured to maintain a pressure of the balloon between 0.2 psi and 1 psi while maintaining adequate fluid flow to cool the balloon.
