Apparatuses for thermal management of actuated probes, such as catheter distal ends

Abstract

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.
