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 flap 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.
L'invention concerne un dispositif médical, tel qu'une sonde d'alimentation nasale-jéjunale, lequel possède un ensemble d'ailerons découpés sur la surface extérieure du cathéter et conçus pour ne pas adhérer facilement à la surface extérieure du cathéter. Ces ailerons sont conçus pour résister à l'évacuation, de manière à permettre des contractions péristaltiques du corps pour propulser le dispositif vers l'avant, tout en permettant que le dispositif soit retiré du corps sans que les ailerons ne causent de traumatisme sérieux aux tissus du canal corporel.
