The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to minimally invasive devices and methods for body lumen access and/or drainage, and devices and methods for creating an open flow passage between two or more body lumens. The invention defines a medical device (100) including an elongate tubular body (110) comprising a proximal end (112) and a distal end (114) a first elongate portion (120) of the elongate tubular body including an outer surface (122) and an inner surface (124) defining a first channel (126) extending along a length of the elongate tubular body a second elongate portion (130) of the elongate tubular body including an outer surface (132) and an inner surface (134) defining a second channel (136) extending along a length of the elongate tubular body a first edge (128) of the first elongate portion is attached to a first edge (138) of the second elongate portion by a hinge member (116) and a second edge (129) of the first elongate portion and a second edge (139) of the second elongate portion 130 are unattached, wherein the elongate tubular body is configured to move between a first configuration and a second configuration.Linvention concerne généralement le domaine des dispositifs médicaux, et létablissement de communication fluidique entre des lumières corporelles.
