IntroductionWe set out to see if permanent interstitial brachytherapy seeds could be safely and reproducibly inserted thoracoscopicaly with the ZEUS Robotic system and intraoperative ultrasound into in-vivo porcine lungs.2. MethodsSix acute pigs underwent robot assisted thoracoscopy using the ZEUS™ system.  A 300 endoscope with video camera was manipulated using the voice activated AESOP™.  The Cook brachytherapy needle was inserted into the lung parenchyma using one of the  ZEUS robotic arms. 3. ResultsAll 8 animals survived the procedures without intraoperative bleeding or air leaks.  The ZEUS system performed well and was able to remotely manipulate the ultrasound transducer and needle to allow deployment of the seeds.  The ultrasound images were of good quality and visualized the needle insertion and seed deployment.  There was no evidence of seed migration in the two chronic animals.4. ConclusionWe have demonstrated that interstitial brachytherapy seeds can be safely inserted into lungs using the ZEUS robotic system with ultrasound image guidance. The L9-5 thoracoscopic ultrasound transducer was inserted through the anterior thoracoport and manipulated with the other robotic arm.  The images were captured using the HDI 5000 sonogram (ATL, Bothell, WT).  Non-radioactive “dummy” seeds were deployed into the left lung using a custom designed hydraulic injector.     Two chronic animals were followed with serial radiographs at one week, one month and three months to assess the long term safety of potential seed migration.  Computed tomograms were also performed at three months .seedslungneedle seeds
