It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3845384 Septum locating apparatus Prosthesis formed by inner and outer inflatable containers Nitro-methyl or ethyl substituted benzotrifluoride Mammary prosthesis with multiple flow spaces Permanent reconstruction implant and method of performing human tissue expansion Multiple envelope tissue expander device Filling tube and seal construction for inflatable implant Tissue expander and method of making and using Implant and inflating construction InventorAssigneeApplicationNo. 764560 filed on 09/20/1991US Classes:128/899, Devices placed entirely within body and means used therewith (e.g., magnetic implant locator)623/8, Implantable623/17.12, Having a fluid filled chamber623/23.67, Inflatable623/901METHOD OF MANUFACTURING PROSTHETIC DEVICEExaminersPrimary: Frinks, Ronald L.Attorney, Agent or FirmInternational ClassA61B 019/00AbstractAccording to the invention, there is provided an implantable prosthetic device inflatable by a self-contained resealable valve in combination with an external locator for determining the position of the valve. The prosthesis includes a flexible outer envelope defining a closed lumen and having a valve attached to an area of the envelope with indicia on the valve responsive to the external locator for determining the position of the valve. A plurality of spaced sensors are each fixedly arrayed on the locator so that when the sensors are in a certain non-juxtaposed relationship with the indicia the sensors orientate with one another, signifying a true location of the valve. A multi-compartmental design having a tethered valve for selective inflation of an inner lumen is also disclosed. The tissue-contacting surface of the outer envelope is micro-textured to minimize tissue capsule contracture.Other References
