Water-jet surgical robot

Waterjet  technology for surgery has been around for some time, yet Procept is already having a successful complete prostate system around it:

"PROCEPT BioRobotics is a privately held medical device company based in the heart of Silicon Valley developing a novel minimally invasive technology for the surgical treatment of prostate disease. PROCEPT’s AquaBeam combines image guidance and robotics to deliver Aquablation, a waterjet ablation therapy that enables targeted, controlled, and heat-free removal of tissue for the treatment of lower urinary tract symptoms as a result of benign prostatic hyperplasia (BPH).

The AquaBeam system is a first of its kind image-guided system delivering a treatment utilizing water and robotics for the targeted removal of prostate tissue. AquaBeam combines image guidance and robotics to deliver Aquablation, a personalized waterjet tissue resection modality. Under real-time image-based ultrasonic guidance, AquaBeam enables surgical planning and mapping, and allows for a controlled resection of the prostate with a high-velocity saline stream. The combination of surgical mapping and controlled resection of the prostate is designed to offer predictable and reproducible outcomes.

The WATER study (Waterjet Ablation Therapy for Endoscopic Resection of prostate tissue) is a prospective randomized U.S. investigational device exemption (IDE) clinical trial evaluating the safety and effectiveness of the AquaBeam System as compared to the current standard of care, transurethral resection of the prostate, or TURP. The WATER study will enroll over 200 male patients between the ages of 45 and 80 years old who have urinary symptoms due to BPH.

The study will be recruiting patients in 20 global sites including sites in the United States, Europe, Australia and New Zealand."
