Publication number: 20120245504Abstract: The present invention is an improved separating device for providing the malabsorptive component of a minimally invasive weight reduction system. This device may be a sleeve, liner, or tubular sheath that alters absorption of compositions through walls of hollow organs (stomach, intestines). The improvement involves better long-term retention through the ability of the device to engage with the interserosal fibrotic tissue formed in an intussusception. The separating device may be a distal extension of a retaining member that is directly engaged with and retained by intussuscepted tissue. Intussusception shrinks a hollow organ to provide a volume reducing restrictive component of a weight reduction system. Securing the separating device to an intussusception avoids retention problems of reference art devices as interserosal fibrosis helps secure the device. Also provided are an apparatus for retaining the device, a device and method for delivering the separating device, and a method for removing it.Type: ApplicationFiled: June 6, 2012Publication date: September 27, 2012Applicant: HOURGLASS TECHNOLOGIES, INC.Inventors: Ivan Tzvetanov, Fan Zhang, Darin Buxbaum, Charles Hsu, Michael Reo

Patent number: 8257374Abstract: Described here are devices and methods for intussuscepting a portion of stomach tissue. Typically the intussusception is created at a position near, but distal to the gastroesophageal junction, and a pouch capable of storing a volume (from about 0 cc up to about 100 cc) is created proximal the intussuscepted tissue. In this way, the amount of food that may be ingested is reduced, helping to ameliorate GERD symptoms, and aiding in weight loss efforts. Some of the devices described here include an expandable member and at least one suction inlet. In these devices, the expandable member is expanded to create a proximal cavity into which the stomach tissue is pulled (e.g., using suction), thereby creating the intussusception.Type: GrantFiled: November 5, 2008Date of Patent: September 4, 2012Assignee: HourGlass Technologies, Inc.Inventors: Charles S. Hsu, Darin H. Buxbaum, Fan Zhang, Ivan T. Tzvetanov, Jennifer T. Blundo
