Abstract: Methods and devices are provided that assist in reducing the risk of unintentional injury in patients during and after surgical procedures, including laparoscopic and open. Improved trocars are provided that include a cannula and an obturator. The cannula comprises first and second sections, the first section including the proximal end of the cannula closest to the surgeon and the second section including the distal end of the cannula proximate a surgical site. The second section of the cannula is of a material that is softer and/or more flexible than that of the first section. By being composed of a softer and/or more flexible material, the second section of the cannula can be maintained adjacent to or abut internal organs during and after a surgical procedure. In some cases, the improved trocar can have a cannula comprised of a single material such as rubber or silicone.
