Atraumatic delivery devices
First Claim
1. A method for delivering a gastrointestinal device in a body comprising the steps of:
- providing a delivery system including an outer sheath and an inner sheath disposed therein,securing a distal portion of a gastrointestinal device outside of the inner sheath, the distal portion being a floppy sleeve surrounding the inner sheath;
guiding the delivery system through the alimentary canal with a ball coupled to a distal end of the inner sheath distal to the sleeve, the outer sheath extending through the stomach and the inner sheath extending through the intestine.

Abstract
Methods and apparatus for delivering an implant device within the digestive system of an animal are presented. An delivery device includes an outer sheath, or container, for storing a proximal portion of the implant device. The outer sheath is moveable relative to the stored portion of the implant device to release the proximal portion from within the outer sheath. The delivery device also includes an inner sheath defining a lumen therein that extends distal to the outer sheath, a moveable element adapted to secure the distal end of the implant to the inner sheath, and a release mechanism coupled to the moveable element for releasing the distal end of the implant. The device also includes a atraumatic tip, or ball, coupled at its distal end to facilitate guiding the delivery device through the gastrointestinal tract.
