Sam Chehayeb has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240062679
    Abstract: A surgical simulation system is provided. The system includes at least one simulated body organ placed upon the base of an organ tray and at least one covering layer placed over the simulated body organ. At least one of the simulated body organ and covering layer includes electro-conductive gel that is operably severable under application of electrical current to simulate electrosurgery in a training environment. The training environment comprises a top cover connected to and spaced apart from a base to define an internal cavity that is partially obstructed from direct observation by a practitioner. The tray, simulated body organs and covering layer are placed inside the internal cavity for the practice of laparoscopic surgical procedures.

  • Patent number: 11034831
    Abstract: A surgical simulator for electrosurgical training and simulation is provided. The surgical simulator includes one or more simulated tissue structures made substantially of a hydrogel comprising a dual interpenetrating network of ionically cross-linked alginate and covalently cross-linked acrylamide. Combinations of different simulated tissue structures define procedural-based models for the practice of various electrosurgical procedures including laparoscopic total mesorectal excision, transanal total mesorectal excision, cholecystectomy and transanal minimally invasive surgery. Methods of making the simulated tissue structures are also provided.

  • Patent number: 9642608
    Abstract: The present invention is directed to tack-free gels and to methods for manufacturing a tack-free gel pad, in which a discontinuous layer of fluorinated ultrahigh molecular weight polyethylene is permanently bonded to the gel pad to provide a tack-free coating. The gel pad may be incorporated into a gel cap to provide a surgical access device having a tack-free surface.
