    • A catheter tip (50, 170, 750) is provided that is adapted for mating attachment to a catheter body (90, 300, 790). In an embodiment, the catheter tip (50, 170, 750) comprises a transducer array (32, 60, 110, 210, 710) in electrical communication with an interconnect (120, 220, 720) and in a mechanical driven relationship with an actuator (80, 730), also in the catheter tip (50, 170, 750), via a drive shaft (38, 82, 732). The transducer array (710) is encapsulated in a potting material body 711 providing a desired ultrasound acoustical transmission, A defined annular space 761 exists between an outer capsule 752 of the catheter tip 750 and the potting material body 711. Oscillating back and forth motion of the transducer array (32, 60, 110, 210, 710) provides ultrasonic imaging functionality that may include real time three-dimensional imaging. Other embodiments of the catheter tip (50, 170, 750) and methods of fabrication also are provided.

    • Alternative embodiments are provided, for use individually or in combination, for thermal management of catheter distal ends and other types of probes such as may be used in catheter and other instruments' diagnostic and interventional devices. In an exemplary embodiment, a catheter distal end (1000) comprises an ultrasound imaging assembly (1003) that comprises an actuator (1004), a drive shaft (1006), a section (1008) of an interconnect (1010), and a transducer assembly (1009). A circulation fin (1018) optionally may be affixed to the bottom (1016) of transducer assembly (1009), and extends into a defined space (1017) to enhance circulation of acoustic transmission medium that is in the defined space (1017). This disperses heat from the actuator (1004) and the transducer assembly (1009). A similar fin (1018) may also, or alternatively, be positioned on the section (1008) of interconnect (1010). Other thermal management approaches also are disclosed.
    • 提供替代实施例,用于单独地或组合地用于导管远端的热管理和其它类型的探针,例如可以用于导管和其他器械的诊断和介入装置中。 在示例性实施例中,导管远端(1000)包括超声成像组件(1003),其包括致动器(1004),驱动轴(1006),互连(1010)的部分(1008)和换能器 装配(1009)。 循环翅片(1018)可任选地附接到换能器组件(1009)的底部(1016),并且延伸到限定的空间(1017)中以增强在限定空间(1017)中的声学传播介质的循环。 这样分散来自致动器(1004)和换能器组件(1009)的热量。 类似的翅片(1018)也可以或替代地定位在互连(1010)的部分(1008)上。 还公开了其他热管理方法。
