  • Mammary implant having shell with unitary rough-textured outer layer
    Patent number: 5674285
    Abstract: A medical implant with an external surface layer of silicone elastomer and having an open-cell structure is made by applying solid particles to the external surface layer of the implant before it is cured, curing the external surface layer with the solid particles embedded therein and then dissolving the solid particles with a solvent that does not dissolve the silicone elastomer. An implant having such an external surface layer is expected to help prevent capsular contraction, to help prevent scar formation, and to help in anchoring the implant within the body.

  • Disposable aspiration sleeve for ultrasonic lipectomy
    Patent number: 5123903
    Abstract: A disposable aspiration sleeve for use with an ultrasonic handpiece, which ultrasonic handpiece includes an ultrasonic horn wherein the cylindrical aspiration sleeve, which is provided with a vacuum tube coupling nipple, is removably mounted at its base to the handpiece and is provided with a supporting mount or mounts on its interior surface positioned in such a manner that the supportive mount or mounts each touches the horn at a vibratory node, thereby acoustically isolating the interior wall portion of the cylindrical sleeve from the ultrasonic horn or tip member.
