  "patent_number": "US 12733932",
  "country": "US",
  "title": "How a Surgical Device Temporarily Anchors in the Intestine",
  "original_title": "Surgical device for controlled anchoring in the intestine",
  "summary": "This patent describes a surgical device designed to temporarily attach itself to the inner wall of the intestine using a controllable suction mechanism and a radially elastic wall.",
  "what_it_does": "This surgical device, as described in the abstract, is designed to temporarily anchor itself to the mucous membrane of the inner wall of the intestine. It features a temporary anchor element with a first substantially cylindrical, multiply-perforated wall that can change its outer diameter in a controlled way due to its radial elasticity. An independent, leakproof inner sheath lines a portion of this wall, creating a suction chamber between the sheath and the perforated wall. A flexible tube connects to this suction chamber, allowing air to be injected or sucked out, which controls the device's anchoring by varying its diameter and creating suction. For example, a surgeon could use this device to hold an endoscope or other surgical tool steady during a delicate procedure inside the bowel.",
  "what_it_does_not_cover": [
    "Does not cover permanent anchoring devices, as this patent describes a 'temporary anchor element'.",
    "Does not cover anchoring methods that rely solely on mechanical clamps, sutures, or adhesives, as it specifies a 'suction chamber' mechanism.",
    "Does not cover devices that anchor in other body organs, as the abstract specifies the 'mucous membrane of the inner wall of the intestine'.",
    "Does not cover anchoring devices where the anchoring force cannot be 'modified in a controlled manner'.",
    "Does not cover devices lacking a 'multiply-perforated wall' or an 'independent leakproof inner sheath' to form the suction chamber."

  "abstract": "A surgical anchor device for being anchored on the mucous membrane of the inner wall of the intestine, the device having a temporary anchor element presenting anchoring that can be modified in a controlled manner and having a first substantially cylindrical multiply-perforated wall presenting properties of radial elasticity whereby the first wall presents an outer diameter that can be varied in controlled manner, wherein a portion of the inner surface of the first wall is lined with an independent leakproof inner sheath having only its longitudinal ends fastened to the anchor element to define a suction chamber between the inner sheath and the first wall, the temporary anchor element being coupled to a flexible or semi-rigid tube extending outside the anchor element, an open end of the injection-suction tube opening out into the suction chamber enabling air to be injected into or sucked out from the suction chamber.",
