  • Patent number: 10350101
    Abstract: 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.

  • Publication number: 20180235794
    Abstract: 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 an artificial stoma device, a gastric sleeve device, an intestinal sleeve device, a combined gastrointestinal sleeve device and permanent and detachable attachment systems. Also described are devices for delivering and deploying the components of the system.

  • Publication number: 20170258618
    Abstract: Elongate flexible medical devices can be 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. An 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.

  • Publication number: 20140180190
    Abstract: 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.

  • Publication number: 20120296254
    Abstract: 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.

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.
