摘要： Devices and methods for shaping an ablation treatment volume formed in fluid enhanced ablation therapy are provided. The devices and methods disclosed herein utilize the interaction of fluids to create ablation treatment volumes having a variety of shapes. In one embodiment, a method for forming an ablation treatment volume having a desired shape includes delivering therapeutic energy to tissue to form an ablation treatment volume and simultaneously delivering a first fluid and a second fluid to the tissue. The first and second fluids can convect the therapeutic energy in a desired direction such that the ablation treatment volume has a desired shape.

摘要： An ultrasonic transducer assembly includes a shaft carried by the support element of the transducer assembly. This shaft supports an array of contacts that extend circumferentially around the shaft and are spaced axially along the length of the shaft. These contacts are electrically connected to conductors which are in turn connected to an ultrasonic transducer array. The shaft of the transducer assembly is received in a receptacle that includes a reciprocating slide that can be opened to insert and remove the transducer assembly from the receptacle. The slide can be closed to lock the transducer assembly in place, and to make electrical contact with the contacts of the shaft.

摘要： An ultrasound transducer assembly having a housing, a transducer array mounted in the housing, and active cooling mechanism positioned adjacent to the transducer array for actively removing heat generated by the array by transport of heat energy from the affected site. The active cooling mechanism may comprise a heat exchanger including a closed loop circulating coolant system circulating coolant, or a single-pass flowed coolant, passing through the heat exchanger, a heat pipe, a thermoelectric cooler, an evaporative/condenser system, and/or a phase change material. One or more heat exchangers may be used having gas or liquid coolants flowing therethrough. The heat exchangers and coolant pumps may be located in various components of the transducer assembly, including the array housing, the connector assemblies or the ultrasound console.
