  • For breast reconstruction, and for the augmentation and enhancement of the aesthetics - size, shape, and texture - of a woman's breasts, there are three types of breast implant devices: saline implants filled with sterile saline solution silicone implants filled with viscous silicone gel alternative-composition implants, filled with miscellaneous fillers - soy oil, polypropylene string, etc. - that are no longer manufactured. (wikipedia.org)

  • Nonetheless, in the 1990s, the saline breast implant was the prosthesis usual for breast augmentation surgery, because of the U.S. FDA's restriction against the importation of silicone-filled breast implants. (wikipedia.org)
  • In surgical praxis, after having emplaced the empty breast implants to the implant pockets, the plastic surgeon then filled each device with saline solution, and, because the required insertion-incisions are short and small, the resultant incision-scars will be smaller and shorter than the surgical scars usual to the long incisions required for inserting pre-filled, silicone-gel implants. (wikipedia.org)

  • Rotary positive displacement pumps fall into three main types: Gear pumps - a simple type of rotary pump where the liquid is pushed between two gears Screw pumps - the shape of the internals of this pump is usually two screws turning against each other to pump the liquid Rotary vane pumps - similar to scroll compressors, these have a cylindrical rotor encased in a similarly shaped housing.

  • In low to medium-vacuum applications, these are sealed with elastomer o-rings. (wikipedia.org)
  • room temperature
  • Their Tg values are well above room temperature, both at around 100 °C (212 °F). Rubber elastomers like polyisoprene and polyisobutylene are used above their Tg, that is, in the rubbery state, where they are soft and flexible. (wikipedia.org)
  • Surgical
  • In the case of the woman with much breast tissue, for whom sub-muscular emplacement is the recommended surgical approach, saline breast implants can afford an aesthetic result much like that afforded by silicone breast implants - a "look" of proportionate breast size, smooth contour, and realistic texture. (wikipedia.org)
