  • Publication number: 20080167629
    Abstract: 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.

  • Patent number: 7220284
    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 and a combined gastrointestinal sleeve device.

  • Publication number: 20050177181
    Abstract: 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.
