Abstract
A medical device, such as a nasal-jejunal feeding tube, having an arrangement of flaps cut from the outer surface of the catheter and configured so as to not readily adhere to the catheter outer surface. The arrangement of flaps are configured to resist egress so as to permit peristaltic contractions of the body to propel the device forward, yet will allow the device to be removed from the body without the flaps causing significant trauma to the tissues of the body canal.
