  • Publication number: 20120053504
    Abstract: Aspects of this invention disclose devices and methods for attachment of a gastrointestinal sleeve. In some embodiments, the attachment device comprises a flexible cuff, a gastrointestinal sleeve interface, and a gastrointestinal sleeve. Some aspects of the invention contemplate the use of T-tags for attachment of the cuff to tissue. In some aspects of the invention, attachment of the sleeve to the cuff is achieved using various fasteners.

  • Patent number: 8118774
    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.

  • Publication number: 20110295181
    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.

  • Patent number: 8012140
    Abstract: 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.

  • Publication number: 20110125211
    Abstract: Methods and devices for gastrointestinal stimulation are disclosed. In one embodiment, disclosed is an electrical stimulator device that includes a circuit board and a battery contained within a base housing; a conduction element; and at least one electrode. In some embodiments, the stimulator base housing can be directly attached to a wall of a body lumen. In other embodiments, the stimulator base housing can be attached to a cuff or a sleeve device. In still other embodiments, one or more elements of the system are free-floating within the GI tract. The devices can be delivered endoscopically, and in some embodiments toposcopically.

  • Patent number: 7794447
    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 a gastric sleeve device, an intestinal sleeve device, and a combined gastrointestinal sleeve device.

  • Publication number: 20090149871
    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.

  • Publication number: 20090012553
    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. 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.

  • Publication number: 20090012544
    Abstract: 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.

    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.
