KindHeart offers a realistic and reproducible human surgical experience within an insufflated patient abdomen for deliberate practice. The Colorectal and Hernia Tissue Cassettes are used with the Abdominal Surgery Simulator. The cassette is used with a KindHeart Abdominal Patient which simulates a human patient from chest to mid-thigh in a supine position. Surgery can be performed using laparoscopic or robotic techniques.
