Aloka Ultrasound and RFA Medical Combine Efforts to Bring State-of-the-Art Technology to the Operating Room

WALLINGFORD, CT - Aloka Ultrasound (Wallingford, CT) and RFA Medical (Fremont, CA) have agreed to combine efforts in promoting their respective medical devices used for ablative procedures. Aloka’s ultrasound technology is the imaging modality used to guide the placement of RFA Medical’s HS-RFA™ bi-polar radio frequency ablation device during ablative procedures.

Aloka and RFA Medical expect the alliance to increase and broaden awareness among surgeons of the important benefits provided by each company’s complementary products. Each company will retain direct control of the sales process for their individual devices.

Aloka’s Chief Operating Officer David Famiglietti commented, “We are excited to be working with RFA Medical as a way to further strengthen our leadership position in the IOUS™ (Intraoperative Ultrasound) market. We are extremely impressed with the advancements RFA Medical has made in the area of bi-polar radio frequency ablation with their HS-RFA™ technology, and especially pleased that they chose to design their laparoscopic device to operate with Aloka’s exclusive end-fire laparoscopic transducer. We look forward to a long-term and mutually beneficial relationship with RFA Medical.”

RFA Medical’s President Steven Daniel went on to say “We are also delighted to be working with such a progressive and forward-looking company as Aloka. We feel that together we can bring the technological benefits from both companies to our mutual current and future customers so that they can better care for their patients.”
