Abstract
Disclosed is an instrument, valve prosthesis and procedure for the minimally invasive implantation of an anti-reflux valve in a patient for the treatment of gastroesophageal reflux disease. Self-anchoring or stapleable one-way anti-reflux valve prostheses are provided, which may be implanted proximate a patient's gastroesophageal junction without open or laparoscopic surgery. An instrument for the peroral insertion, positioning and fixing of the valve prosthesis to the tissue of the esophagus is described for the implantation of either the self-anchoring or stapleable prosthesis.
Claims17
A peroral prosthesis system for treatment of gastroesophageal reflux disease in a patient comprising:
- an anti-reflux valve prosthesis comprising:
- a mounting ring made of an expandable, compressible memory material;
- an anchor comprising staples for fixing the mounting ring in the lumen of the esophagus;
- and
- a one-way valve depending from the mounting rings for allowing orthograde passage of swallowed material, and impeding the passage of gastric content;
- and
- a peroral implantation tool for perorally inserting and positioning the prosthesis at a distal end of the lumen of an esophagus, and fixing the prosthesis to the lumen wall of the esophagus, comprising an intralumenal, circular surgical stapler, having an annular space connected to a vacuum source and a prosthesis holder.
An anti-reflux valve prosthesis comprising:
- a mounting ring;
- an array of at least one row of tissue anchors presenting at least 8 points extending outward from the mounting ring, in the direction substantially parallel to the esophagus the anchors having staple points for engaging the lumen wall of an esophagus and fixing the mounting ring in the lumen of the esophagus;
- and
- a one-way valve depending from the mounting ring, for allowing orthograde passage of swallowed material, and impeding the passage of gastric content.
