  • Publication number: 20090174707
    Abstract: Various methods, techniques or modules are provided to allow for the automated analysis of the 3-D representation of the upper front torso (i) to recognize 3-D anatomical features, (ii) to orient the subject with reference to their anatomy or a display, (iii) to determine dimensional analysis including direct point-to-point lines, 3-D surface lines, and volume values, (iv) to simulate the outcome with the addition of breast implants including breast and nipple positioning, (v) to assist in the selection of the breast implants, and/or (vi) to assist in the planning of breast surgery. The automated analysis is based on the analysis of changes in a 3-D contour map of the upper torso, orientation analysis of 3-D features and planes, color analysis of 3-D features, and/or dimensional analysis of 3-D features and positions of the upper torso.

  • Publication number: 20090125107
    Abstract: A medical implant assembly and method having a medical implant, e.g. a breast prostheses, attached to a biological interface. The biological interface is comprised of a dermal material with capsular contracture inhibiting properties so that once the medical assembly is inserted into the host, the biological interface, which is intimately coupled to the implant, prevents/reduces capsular contracture formation around the implant. The biological interface comprises a plurality of apertures along its periphery, and attaches to the medical implant by receiving a plurality of attachment flaps or appendages located on the exterior surface of the medical implant within or through the apertures. The attachment of the biological interface is such that the assembly remains intact even where the attachment flaps loosen upon expansion of the implant after insertion into a host, as where the implant is therein injected to a desired dimension.

  • Patent number: 5865810
    Abstract: A skin protector and accessories for protection of a skin incision during minimally invasive surgical procedures requiring protection from thermal and frictional abrasion, for example, during ultrasonic-assisted liposuction. The skin protector incorporates an outer configuration to assist in maintaining in situ positioning of the skin protector during operative procedure. An introducer member for blunt dissection of a tunnel is provided to allow easy insertion of the skin protector. A driver member for dilatation of the skin incision, and for facilitating implantation and withdrawal of the skin protector is provided with a complementary configuration to that of the skin protector to cause the skin protector to be taken along with rotary motion of the driver member.

  • Patent number: 5651773
    Abstract: A skin protector and accessories for protection of the skin incision during ultrasonic-assisted liposuction from thermal and frictional abrasion includes a skin protector made from sterilizable material which resists deformation and incorporates an outer configuration to assist in maintaining in situ positioning of the skin protector during operative procedure. An introducer member for blunt dissection of a tunnel is provided to allow easy insertion of the skin protector and ultrasonic probe. A driver member for dilatation of the skin incision, and for insertion and removal of the skin protector is also provided to assist in the use of the skin protector, properly speaking.

  • Patent number: 5531786
    Abstract: This invention relates to a medical prosthesis containing a gel filler material comprising principally a cellulose derivative in water. The gel filler in the prosthesis may further contain a lubricating agent. The invention also relates to a method of augmenting or reconstructing a human breast comprising the steps of subcutaneously implanting a medical prosthesis with the gel filler material into a human body. In another aspect, the invention relates to a method of preparing medical protheses comprising the steps of filling an outer envelope of a medical-grade elastomer with the gel filler material and sealing the envelope to form a medical prosthesis. The components of the gel are preferably biocompatible so as not adversely to affect human beings. The materials used to make the gel filler are non-toxic. The prostheses of the present invention have similar characteristics to the human breast. These protheses may be used for breast augmentation or reconstruction.

  • Patent number: 5480430
    Abstract: A fluid-filled breast prosthesis for surgical implantation beneath the skin having a wrinkle resistent, elastic outer shell which is adapted to resist deformation or wrinkling during movement of the fluid filler. The outer shell, or envelope, has superior and inferior portions. The wall of the superior portion of the shell is substantially thickened with respect to the wall thickness of the inferior portion of the shell. The shell forms an envelope with an inner cavity which is filled with a biocompatible liquid such as saline. The presence of the thickened superior portion of the shell prevents wrinkles from forming in the breast prosthesis during fluid displacement such as occurs when the breast prosthesis recipient changes her anatomical position. The differentially thickened shell has a posterior base portion which may be reinforced to further stabilize the prosthesis.

  • Patent number: 5379235
    Abstract: A system and method for measuring the biomechanical properties of a healing wound in a specimen which utilize a chamber for applying an increasingly negative pressure over time to an area of tissue containing the wound, markings on the area for facilitating measurement of expansion of the area, a pressure measurement device for measuring the pressure in the chamber as a function of time, one or more cameras for obtaining multiple views of the area over time, a digitizer for generating a digital representation of each of the views, and a processor for determining a strain value from each digital representation and for correlating each strain value with a pressure measurement corresponding to the same point in time to provide a stress-strain relationship.

  • Patent number: 5282857
    Abstract: This invention relates to a medical implant, which comprises an outer envelope and a gel filler material, wherein the gel comprises water and a cellulose gelling agent. The gel in the implant may further contain a lubricating agent. The components of the gel are a biocompatible and do not adversely affect human beings. Implants containing the lubricating agent have a decreased tendency of failure caused by internal friction on the envelope. The implants of the present invention have similar characteristics of the human breast.

  • Patent number: 5092348
    Abstract: An implantable tissue expansion device with an external surface layer of silicon elastomer, at least a portion of which contains a texture or open cell sturcture.
