摘要:
A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position, and a moveable barrier is disposed between the cartridge and anvil members to help acquire a dual fold of tissue. The tissue treatment device can be repositioned to form multiple plications within the organ.

Methods and devices for maintaining a space-occupying device in a fixed relationship relative to a patient's stomach by manipulation of the stomach. In one variation, two or more regions of the stomach wall are brought into approximation with one another and secured together in a manner that secures a space-occupying device within the stomach of the patient. In another variation, two or more regions of the stomach wall are wrapped around a space-occupying device to maintain the position of the space-occupying device relative to the stomach wall. In another variation, a system having a space-occupying member and a locking member capable holding the space-occupying member against the inner wall of the stomach are provided. In a further variation, a pouch is created within the stomach that receives and retains a space-occupying device.

An overtube apparatus for insertion into a body is described herein. The assembly includes an overtube having a lumen defined throughout. The distal end of the overtube member has two or more windows in apposition configured to draw in tissue via a vacuum. A drive tube, which also defines a lumen, is inserted and is freely adjustable within the overtube. A spiral or helical fastener, which is temporarily attached to the drive tube distal end, is positioned within the overtube lumen. Endoscopic devices can be inserted within the drive tube lumen and advanced past the distal ends of both the drive tube and overtube. A pump provides the vacuum to draw apposed regions of tissue from within a hollow body organ into the windows of the overtube. Once the tissue has been invaginated, the drive tube is rotated to advance the fastener into the tissue to fasten them together.

Methods and devices for providing a minimally-invasive placement of a mechanical structure for reducing the volume of a hollow body organ. Anchors may be secured within the hollow body organ and then cinched together using a tensioning member to form a stricture within the hollow body organ. In another embodiment a tensioning member may be threaded along the hollow body organ and then cinched to reduce the volume. The strictures may be placed anywhere within the hollow body organ, and more than one stricture may be formed within the hollow body organ.

摘要:
A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

Gastric space occupying devices are provided that include a stent configured for deployment in the gastrointestinal tract of a patient, and in particular, for deployment in the esophagus or the stomach. Secured to the stent is an expandable member that is adapted to reside within the patient's stomach. When expanded, the expandable member occupies a predefined volume within the patient's stomach and is further tethered to the deployed stent, thereby retaining or anchoring the expandable member within the stomach. Methods and systems for the deploying the space occupying devices are also provided.
