Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Serial No. 62 / 478,998, filed March 30, 2017, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The present invention relates generally to the field of body cavity drainage. In particular, the present invention relates to systems and methods for creating open flow paths between tissue walls of varying thickness. Background technique [0004] Draining bodily fluids within a tract or other location within the body to a collection site outside the body through a percutaneously created pathway can be accompanied by difficulties. For example, bile is a yellow-brown fluid produced by the liver and transported through the bile ducts to the small intestine to aid in the digestion of lipids. Bile duct obstruction may cause bile to build up in the body, which can...
