Fluid-Collection Ring for Thermal Therapy Device
A medical device comprises an ultrasound applicator comprising a shaft having proximal and distal ends; a plurality of channels defined in the shaft and extending from the proximal end of the shaft, including an ultrasound channel and a cooling channel; one or more ultrasound transducers disposed in the ultrasound channel; an ultrasound window defined in the shaft and aligned with the one or more ultrasound transducers; and a handle attached to the proximal end of the shaft. A fluid-collection ring is disposed on a distal side of the handle. The fluid-collection ring has an inner edge and an outer edge, the inner edge defining a hole through which the shaft extends. A distal side of the fluid-collection ring has a concave shape and is configured to direct fluid away from the handle.
