Improved Drainage Valve implantation in a patient's Eye for the treatment of glaucoma

摘要

A Drain valve (10) surgically implanted in the eye (OR) of a patient for the treatment of glaucoma, which comprises a main body (11) and a Drainage Tube (12) connected at one end with the main body (11) and is intended to be implanted in the eye (or ma) Nera that its distal end to penetrate inside the anterior chamber (AC) of the eye (GO)Allowing drainage of aqueous humor (UA) towards the outside; where the valve (10) is characterized by a series of significant improvements include: 1) a configuration (12a, removable12b) of the drainage Tube (12) that allows to adapt (F1) along the drainage Tube (12) for Surgical implantation of the valve (10); 2) a Profile of Crushed or flat section (12) of the drainage Tube (12, 12a, 12b) designed to reduce the profile in the Rad IAL (IR) drainage Tube (12) on the surface of the eyeball (GO),3) no obstructions between the portion of the tip (12F) drainage Tube (12), prepared to penetrate the Interior of the eyeball (GO, CA), and the remaining portion (12b) of the drainage Tube (12); 4) a series of containers or Sacks of retention (11b Distributed along) The Lower Surface (S) or dorsal Lower Main Body (11),In contact with the surface of the eyeball (GO), where the Sacks of retention (11b) are associated with the respective Holes (11a) distributed on the same main body (11) of the valve that are prepared to receive and retain the aqueous humor (UA), thereby allowing me Improving lubrication of the eyeball in the region of the valve.Once implanted; 5) an Opening (11c) divergent fanned out on the dorsal Surface (S), which is not in contact with the eyeball, the main body (11) of the valve, to Channel the aqueous humor (UA) and improve Lubrication around the vu00e1lvul To Drainage (10), once implanted; and 6) Revised settings.Compared to conventional Drain Valves, which allows, during surgery, a provision of the Holes closest to the Iris (11d) for the insertion of the thread for fixing the valve to the surface of the eyeball.These improvements of the Drain valve (10) provides significantly improved performance and Higher current Drain valves for use in the Medical Field for glaucoma Therapy.
