- Titre Device for shearing tissue
- Description The invention consists in an implant composed of magnets linked together by a wire. Through natural ducts—such as the esophagus—and using endoscopic tools, the magnets are positioned over the tissue to be cut (such as the wall between the esophagus and a diverticulum). The magnets strongly compress the tissue thus trapped, cutting it off from its blood supply. This results in tissue necrosis between the magnets and scarification at the edges, preventing an open wound. At the same time, the wire linking the magnets exerts a compression force on the remaining tissue, due to gravity affecting the magnets or to any other system creating a tension, resulting in a slow and atraumatic cutting of the tissue.
- Bénéfices - The core of the invention is the wire linking the magnets, which serves as a cutting tool. Once the tissue trapped between the magnets has necrotized, the wire gently cuts the remaining wall by shearing tissue due to the magnets’ weight or another traction system.
- The use of a wire to act as cutting tool is the novel aspect. The invention’s main advantages are its non-invasiveness, a slow process in comparison with using a scalpel, and the variability in the size and shape of the cut.
