  • Publication number: 20140148828
    Abstract: Apparatus and methods are provided for forming a gastrointestinal tissue fold by engaging tissue at a first tissue contact point and moving the first tissue contact point from a position initially distal to, or in line with, a second tissue contact point to a position proximal of the second contact point, thereby forming the tissue fold, and extending an anchor assembly through the tissue fold from a vicinity of the second tissue contact point. Adjustable anchor assemblies; as well as anchor delivery systems, shape-lockable guides and methods for endoluminally performing medical procedures, such as gastric reduction, treatment of gastroesophageal reflux disease, resection of lesions, and treatment of bleeding sites; are also provided.

  • Patent number: 8663236
    Abstract: Transgastric abdominal access methods and apparatus are described herein. A shape-lockable elongate body can be advanced endoluminally in a flexible state into the stomach, where an opening is created through the stomach wall. The opening can be created endoluminally or by incising instruments placed through the abdominal wall. The elongate body can be transitioned to a rigid state prior to, during, or after advancement into the patient and is passed through the opening into the peritoneal cavity. A dilation balloon can be positioned simultaneously within the elongate body and within the tissue opening such that the elongate body can be advanced through the tissue opening. A flexible needle catheter can also be delivered through the elongate body or an endoscope to provide for insufflation prior to cutting or piercing through the stomach wall. Also, tissue closure devices and methods to close the opening created through the stomach wall.
