Definitions

  • the present invention relates to prosthetic implants in general and prosthetic breast implants, in particular.
  • Implant rupture or leakage can be due to an injury or just normal wear - even the pressure of a mammogram can contribute to implant rupture.
  • Plastic surgeons usually recommend the removal of a ruptured implant even if the silicone is still enclosed within the scar tissue capsule, because the silicone gel may eventually leak into surrounding tissue.
  • Saline implants have been known to become infected and leak, often causing infection in surrounding tissues.
  • Silicone breast implants are known to be associated with calcium deposits in the breast. These calcium deposits can make it even more difficult to obtain a clear mammogram and can be mistaken for possible cancer (necessitating additional surgery or biopsy). Although the calcium deposits do not appear to be harmful, they can be indicative of a nearby cancer. Therefore, the presence of silicone implants may make it difficult to distinguish between the predictable effects of the implant and actual evidence of cancer. It is, therefore, the general object of the invention to overcome these and other deficiencies common to conventional breast implants.
  • the breast implant will not interfere with x-ray and mammogram examinations.
  • a prosthesis for physical implant comprising an outer envelope and a filler of a yieldable non-liquid substance.
  • the filler substance will consist of a fibrous material, e.g. cotton.
  • the density of the fibrous material may be uniform, or may vary with respect to a different location.
  • the outer envelope will be of rough surface silicone.
  • Fig. 1 is a perspective view of a fiber filled breast implant prosthesis
  • Fig. 2 is a top view of the implant prosthesis of Fig. 1
  • Fig. 3 is a side view of the implant prosthesis of Fig. 1;
  • Fig. 4 is a schematic cross-section of the breast implant prosthesis of Fig. 1;
  • the prosthesis generally designated A comprises an outer envelope B of rough surface silicone, which may be of the conventional type commonly used in prevailing prosthetic implants.
  • the envelope B is filled with a fibrous material C, preferably of cotton or synthetic fibers such as DacronTM, or GortexTM (the latter two are currently widely used for surgical stitching procedures); however, any other fibrous material of similar character to those noted above may be employed.
  • a fibrous material C preferably of cotton or synthetic fibers such as DacronTM, or GortexTM (the latter two are currently widely used for surgical stitching procedures); however, any other fibrous material of similar character to those noted above may be employed.
  • the silicone envelope B is filled with the fiber content whereby the filling retains a uniform texture and density, with a flexible propensity to return to the conscripting shape of the encasing envelope.
  • the method employed for filling the envelope B is by encasing or "trapping" various sized fibers C or fiber aggregates.
  • Envelope B is seamlessly and hermetically sealed to prevent direct contact with body tissue.
  • the 'solid' nature of the fiber implant provides a solution to the problem of 'leakage' penetrating surrounding tissue, a problem commonly associated with conventional breast implants, and will offer a greater 'lifespan' thereby diminishing the need for replacement surgery at irregular and close intervals.
  • the dense fibers also provide a solution to breast x-ray and mammogram examinations, since the cotton, GortexTM , DacronTM, and similar fibers are radiolucent.
  • the fiber filling has a specific gravity much lower than lgr/cm 3 and will therefore virtually eliminate the problem of 'sagging' that plagues both the natural as well as the conventional saline water or other liquid substances filled implanted breasts.
  • the unattractive 'wavy' appearance will disappear in most if not all implants due to the especially light yet dense composition of the encased prostheses.
  • the fiber implants will retain a structural integrity and will provide strength and stability over significantly longer periods of time, precluding the necessity of repetitive cosmetic surgeries.
  • the fiber implant is virtually maintenance free and has the quality of reproducing a tactile response similar to breast tissue - providing additional attractive incentive for use as a preferred breast prosthesis for implant.
  • Fiber fillings also afford the unique ability to be prepared as layers with varying degrees of flexibility or firmness. This can be achieved by fusing or otherwise binding non-homogeneous layers of filling each comprised of loose, bulk, or aggregated fibers of differing strength, density, length, etc. - all with a view of achieving the optimal result for the individual patient.
  • the solid/non-fluid components of the implant are lightweight, shaped, elastic, long lasting and do not interfere with x-ray and mammogram examinations.
