Patent number: 8870808Abstract: A pyloric valve is provided for inhibiting the flow of chyme through the pyloric region of the gastrointestinal tract. The pyloric valve includes a blocking portion having at least one axially-aligned annular flange defining a central opening and a support having a rim and a support surface. The support may be disposed in a nested position wherein the support surface is disposed within the central opening and an inverted position wherein the support surface is disposed away from the central opening. The pyloric valve may further include a sleeve that may have a beveled distal end. The pyloric valve may be constructed of silicon. Also provided are methods of inserting and removing the pyloric valve, which each include a step of manipulating the support between its inverted and nested positions. Insertion and removal systems are also provided for use with the pyloric valve.Type: GrantFiled: December 23, 2011Date of Patent: October 28, 2014Assignee: E2, LLCInventors: Buket Grau, David Robert Gale, Sam Anne Musgrave, George McGee Perkins, Mark Jeffrey Edhouse, Marc Graham, Christopher Kadamus

Patent number: 8579849Abstract: A pyloric valve is provided for inhibiting the flow of chyme through the pyloric region of the gastrointestinal tract. The pyloric valve includes a blocking portion having a disc-shaped inlet and a helical flange. The helical flange may be disposed in a contracted position defining a contracted length and a contracted diameter and an extended position defining an extended length and an extended diameter, wherein the extended length is longer than the contracted length and the extended diameter is smaller than the contracted diameter. The pyloric valve may further include a sleeve that may have a beveled distal end. The pyloric valve may be constructed of silicon. Also provided are methods of inserting and removing the pyloric valve, which each include a step of manipulating the support between its contracted and extended positions. Insertion and removal systems are also provided for use with the pyloric valve.Type: GrantFiled: February 1, 2012Date of Patent: November 12, 2013Assignee: E2 LLCInventors: Buket Grau, David Robert Gale, Sam Anne Musgrave, George McGee Perkins, Mark Jeffrey Edhouse, Marc Graham, Christopher Kadamus

Patent number: 8517972Abstract: A pyloric valve for regulating the flow of fluids in the pyloric region a patient's gastrointestinal tract is disclosed herein. In one embodiment, a pyloric valve includes a plurality of axially connected blocking members located along a longitudinal axis of the valve in a proximal to distal direction. Each blocking member of the valve preferably includes at least one blocking portion defining at least one entryway adapted to receive fluids such as chyme therethrough. The at least one entryway of each blocking member is preferably not aligned with the at least one entryway of each blocking member adjacent thereto along the longitudinal axis. The non-alignment of the at least one entryways of the blocking members preferably creates a non-linear path for fluids such as chyme to travel through the pyloric region of the patient.Type: GrantFiled: June 22, 2012Date of Patent: August 27, 2013Assignee: E2 LLCInventors: Marc Graham, Buket Grau
