Pajunk® set a milestone in the industry in terms of ultrasound needle visibility with the Cornerstone reflectors technology. Our SonoSystem catheter sets for CPNB come equipped with the same true echogenic needles in 3 different tip varieties (Tuohy, Facet, Sprotte®). With the new addition of SonoLong Echo catheter, we succeeded in developing an ultrasound-visible, MRT-visible, radiopaque catheter and also MRI compatible.
