  • Patent number: 11759304
    Abstract: An apparatus enables concurrent restoration of a gastroesophageal valve and tightening of the lower esophageal sphincter. The apparatus comprises a longitudinal member having a distal end arranged to be received within a stomach, a tissue shaper at the distal end of the longitudinal member that forms a gastroesophageal valve from stomach tissue, and a tissue gatherer that gathers fundus tissue at or aboral to the gastroesophageal junction to reduce an esophageal opening into the stomach and tighten the lower esophageal sphincter. A fastener deployer then deploys at least one fastener pair to maintain both the restored gastroesophageal valve and the tightened lower esophageal sphincter.

  • Patent number: 11627958
    Abstract: A patient's stomach may be secured to the patient's diaphragm. A method to accomplish this includes visualizing a wall of a patient's stomach adjacent the patient's diaphragm from within the patient's stomach, inserting a fastener deployment apparatus down the patient's esophagus and into the mammalian's stomach, and fastening the patient's stomach to the patient's diaphragm with the fastener deployment apparatus and from within the stomach. The procedure may be employed to advantage to treat a hiatal hernia, for example, either alone or in conjunction with the restoration of the patient's gastroesophageal flap valve.

  • Patent number: 11484305
    Abstract: Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together include a first member, a second member, and a connecting member extending between the first and second members. One of the first and second members has a configuration alterable by a deployment wire to permit release of the fastener from the deployment wire after deployment and without causing excessive tissue trauma.

  • Patent number: 11395672
    Abstract: Stomach tissue is manipulated to form, for example, a restored flap of a gastroesophageal flap valve. The manipulation includes gripping stomach tissue from within the stomach while the stomach is inflated to promote visualization and stabilization of the gripped stomach tissue. Once the stomach tissue is gripped, the stomach is deflated and pulled into a mold. The molded tissue is then fastened with at least one fastener. The stomach is inflated to a first pressure during visualization and then to a second higher pressure during the stomach tissue gripping.

  • Patent number: 11395671
    Abstract: A transoral gastroesophageal flap valve restoration device has sufficient flexibility and dimension to be passed through the mouth, throat, and esophagus of a patient into the patient's stomach. The device includes a first member and a second member hingedly coupled to the first member. The first and second members are configured to flex in a direction to follow the esophageal path into the stomach and to be substantially rigid when forming the restored gastroesophageal flap valve.

  • Publication number: 20210338230
    Abstract: Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together. The fasteners include a first member, a second member, and a connecting member extending between the first and second members. The first and second members are substantially parallel to each other. The fasteners may be deployed in limited spaces and in various applications including the restoration of a gastroesophageal flap valve.
