  • Publication number: 20240041586
    Abstract: A method of augmenting or reconstructing a breast of a patient includes providing an implantable member and implanting the implantable member. The implantable member includes an exterior surface defined by an anterior face and a posterior face, wherein one of the anterior face and the posterior face includes at least one fixation region defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face. The implantable member is implanted into a breast of a patient such that the fixation region of the implantable member generally aligns with the pectoralis major muscle group or the pectoralis minor muscle group.

  • Patent number: 9592411
    Abstract: A low profile explosion proof by containment enclosure includes a base wall having first and second edge sections that are joined with third and fourth edge sections to define a substantially planar surface. First and second side walls extend from the first and second edge sections, and third and fourth side walls extending from the third and fourth edge sections and are joined with the first and second side walls. The base wall, first and second, and third and fourth side walls define an interior zone. A cover is coupled to the first and second, and third and fourth side walls to enclose the interior zone and provide containment to any flammable events. At least one of the first and second side walls, third and fourth side walls, base wall, and cover includes one or more unobstructed openings that provide fluid drainage while also providing containment to any flammable events.

  • Publication number: 20150132469
    Abstract: Implantable prosthesis, components of prosthesis, and methods of making same are provided. The methods generally include the steps of providing an implant shell, applying a curable fluid composition to the shell to form a coating thereon and applying a particulate component to the composition. The composition is a mixture, for example, an emulsion, containing a silicone-based elastomer dispersion and droplets of a suspended leachable agent. After the elastomer is stabilized and cured, the particulate component and leachable agent are removed, resulting in an implantable member having a porous, open-cell surface texture designed to be effective in reducing incidence of capsular formation or contraction.
