  • 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: 20070198074
    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: 20060020254
    Abstract: Disclosed are methods and devices for attaching an implant such as a gastrointestinal bypass tube to a position within a tubular organ. Tissue adjacent an attachment site is stabilized using vacuum, and tissue anchors are advanced through the stabilized tissue.

  • Publication number: 20050251142
    Abstract: Disclosed is a bone fracture fixation device, such as for reducing and compressing fractures in the proximal femur. The fixation device includes an elongate body with a helical cancellous bone anchor on a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. The device is rotated into position across the fracture or separation between adjacent bones and into the adjacent bone or bone fragment, and the proximal anchor is distally advanced to apply secondary compression and lock the device into place. The device may also be used for soft tissue attachments.
