Embodiment Construction

[0020] This disclosure is not limited to the particular embodiments described herein. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting beyond the scope of the appended claims. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the industry to which this disclosure belongs.

[0021] Embodiments herein relate to a self-expanding stent implantable in a patient, which acts as a one-way valve for controlling the passage of substances through the patient's gastrointestinal tract (GI). For example, the stent is configured to allow passage of feces or other material in one direction once sufficient pressure is applied to change the stent from a closed, twisted configuration to an open, expanded configuration. In some embodiments, the stent includes a hollow tubular elongated structure extending along a central axis, the hollow tubu...

Abstract

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application 62 / 873,241, filed July 12, 2019, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present disclosure relates to medical stents, and more particularly to stents and methods for managing the passage of substances through body lumens. Background technique [0004] The sphincter muscle in human anatomy plays an important role in sealing and preventing leaks in organs and blood vessels. Examples of sphincters in humans include the lower esophageal sphincter (LES) and the internal / external anal sphincter (IAS / EAS). Complications affecting sphincter function can cause discomfort and embarrassment that impair a patient's quality of life. [0005] Fecal incontinence is an example of sphincter dysfunction, considered to be the inability to control bowel movements, resulting in th...
