Patent number: 8182459Abstract: The present invention provides devices and methods for attachment of an endolumenal gastrointestinal device, such as an artificial stoma device, a gastrointestinal bypass sleeve or other therapeutic or diagnostic device, within a patient's digestive tract. In one application of the invention, an endolumenal bypass sleeve is removably attached in the vicinity of the gastroesophageal junction to treat obesity and/or its comorbidities, such as diabetes. The bypass sleeve may be at least partially deployed by eversion.Type: GrantFiled: October 11, 2006Date of Patent: May 22, 2012Assignee: ValenTx, Inc.Inventors: Mitchell Dann, Joshua Butters, Greg Fluet, Lee Guterman, Jonathan Kagan, Paul Swain, Gerard von Hoffmann, James Wright

Patent number: 8118774Abstract: Disclosed herein are elongate flexible medical devices which are capable of axial elongation through the mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular device having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tube upon itself, causing an axial shortening of the overall length of the device. The original length of the device can be restored by coupling a pressurized media to the proximal end of the sleeve. If the distal end of the sleeve is temporarily restricted or closed, the pressurized media causes the distal end of the sleeve to travel distally until the full length of the sleeve has been restored.Type: GrantFiled: September 25, 2007Date of Patent: February 21, 2012Assignee: ValenTx, Inc.Inventors: Mitchell Dann, Greg Fluet, James Wright

Publication number: 20110295181Abstract: An apparatus and method are provided to treat a stenosis. A delivery device is provided that has an elongate tubular member coupled therewith. The elongate tubular member has an outside surface that is configured to prevent adherence of in vivo matter. The tubular member has a proximal end and a distal end and is reinforced along its length to maintain open lumen under a transverse load. The tubular member is placed in the vasculature such that the distal end of the elongate tubular member is disposed distal of a stenosis. The proximal end of the elongate tubular member is disposed inside the vessel, preferably at a location proximal of the stenosis. Thereafter, after a therapeutic period, the elongate tubular member is removed intact.Type: ApplicationFiled: June 1, 2011Publication date: December 1, 2011Applicant: HEMOSPHERE, INC.Inventors: Mitchell Dann, Judson A.

Patent number: 8012140Abstract: Disclosed herein is a method of treating a patient, that includes providing a gastrointestinal sleeve device having an elongate tubular body, with a proximal opening and a distal opening; and positioning the gastrointestinal sleeve device in the patient's digestive tract such that the proximal opening of the tubular body is positioned at the native gastroesophageal junction to receive ingested food and liquids from the patient's esophagus and the distal opening of the tubular body is positioned in the patient's jejunum. The tubular body can then be attached near its proximal opening to the patient at the native gastroesophageal junction.Type: GrantFiled: May 9, 2006Date of Patent: September 6, 2011Assignee: ValenTx, Inc.Inventors: Jonathan Kagan, Mitchell Dann, Lee Guterman, Joshua Butters, Paul Swain, T.

Patent number: 7794447Abstract: Apparatus and methods are described for treatment of morbid obesity using minimally invasive techniques. The apparatus includes a system of components that may be used separately or in combination for effectively reducing stomach volume, bypassing a portion of the stomach and/or small intestines, reducing nutrient absorption in the stomach and/or small intestines and/or depositing minimally or undigested food farther than normal into the intestines, thereby stimulating intestinal responses. The components described include a gastric sleeve device, an intestinal sleeve device, and a combined gastrointestinal sleeve device.Type: GrantFiled: July 30, 2004Date of Patent: September 14, 2010Assignee: ValenTx, Inc.Inventors: Mitchell Dann, Lee Guterman

Publication number: 20090149871Abstract: The present invention provides devices and methods for attachment of an implanted device, such as an artificial stoma device, a gastrointestinal sleeve device or an attachment cuff, within a patient's digestive tract for treatment of obesity. Special surgical fasteners provide a lasting and durable attachment to the gastrointestinal tissue without causing excessive pressure that could result in tissue erosion and detachment of the implanted device. Fastener delivery devices that facilitate peroral placement and deployment of fasteners and secondary devices are also provided. Also described are implantable devices and attachment means that avoid causing excessive pressure within the tissue by having compliance that is compatible with the gastrointestinal tissues where it is attached.Type: ApplicationFiled: December 29, 2004Publication date: June 11, 2009Inventors: Jonathan Kagan, Mitchell Dann, Greg Fluet, Sayeed Ikramuddin, Paul Swain, Richard Thomas, Gerard Hoffmann, Mary Wilmore

Publication number: 20090012553Abstract: Disclosed herein are systems and methods for attaching or maintaining the position of a therapeutic or diagnostic device in a body lumen, such as the GI tract without necessarily requiring any penetrating attachments through any body walls. The system can include at least two elements: a proximal orientation element and a distal support element. The proximal orientation element can be configured to reside at least partially within the esophageal lumen and the distal support element can be configured to reside in the stomach, such as along the greater curve of the stomach. An intragastric support system can have a first configuration in which the long axis of the proximal orientation element is substantially parallel and/or substantially coaxial with the long axis of the distal support element, and a second configuration in which the long axis of the proximal orientation element is not substantially coaxial with the long axis of the distal support element.Type: ApplicationFiled: June 9, 2008Publication date: January 8, 2009Applicant: ValenTx, Inc.Inventors: Christopher Paul Swain, Mitchell Dann, Greg Fluet, John Hancock, Gerard von Hoffmann, James Wright

Publication number: 20090012544Abstract: Disclosed herein are systems and methods for treating a patient that has undergone a bariatric surgical procedure, to promote weight loss in the patient. The systems and methods can involve positioning a gastrointestinal bypass sleeve within a portion of the altered GI anatomy to create or restore a restriction, and/or create a malabsorptive effect via a gastric and partial intestinal bypass. The bypass sleeve can include a proximal attachment element for attaching the proximal end of the sleeve in a penetrating or non-penetrating manner at the gastroesophageal junction, stomach, neo-stomach, or other locations. The bypass can be placed during the same operative session as the bariatric surgical procedure, or alternatively at a later date.Type: ApplicationFiled: June 9, 2008Publication date: January 8, 2009Applicant: VALEN TX, INC.Inventors: Chris Thompson, Mitchell Roslin, Mitchell Dann, Greg Fluet, James Wright
