Publication number: 20080140198Abstract: An method for enhanced follicular tissue transplantation and management is provided. Follicular tissue is first obtained from a donor during a dedicated harvesting procedure or as a by-product of another cosmetic surgery procedure, then cryopreserved and stored. When implantation is desired, the cryopreserved tissue is thawed, and the tissue that survived the cryopreservation and thawing processes is implanted in the recipient. In another aspect of the invention, the harvesting process is conducted when the quality of donor follicular tissue is as optimal as possible, and is stored in cryopreserved form until the donor requires implantation thereof, such that the newly implanted thawed follicular tissue is of higher quality than the recipient's current follicular tissue. In yet another aspect of the present invention, a method for managing the business aspects of the transplantation process, including harvested follicular tissue grading, cataloguing and banking is provided.Type: ApplicationFiled: December 6, 2007Publication date: June 12, 2008Inventor: Robin Unger

Patent number: 7083648Abstract: Percutaneous skin access devices include a plurality of locked connecting units mounted to the exterior surface of an implantable medical object which, in position, is configured to penetrate the skin of a subject. The locked connecting units may be mounted directly onto the desired surface of the exterior of the device or may be held on a substrate sheet, which is mounted to the exterior surface of the device. In position, the locked connecting units engage with soft tissue which can include the skin to form a bio-junction layer which includes mechanical and bio-sealing connection between the device body and the soft tissue. The configuration at the bio-junction layer secures the medical object in location in the subject even for long-term indwelling applications in a manner, which inhibits soft tissue infection. The locked connecting units may be rigid or semi-rigid for longer-term indwelling applications, and semi-rigid and/or resilient for shorter term indwelling applications.Type: GrantFiled: November 30, 2000Date of Patent: August 1, 2006Assignee: East Carolina UniversityInventors: Chang Yu, Glenn Harris

Patent number: 6974697Abstract: The present invention relates to in vitro cultured skin substitutes, and in particular to in vitro cultured skin substitutes that have improved barrier function. In some embodiments, improved barrier function is a result of improved culture conditions, while in other embodiments, improved barrier function results from genetic modification of keratinocytes. Improved culture conditions to improve barrier function include organotypic culture in the presence of linoleic acid and/or linoleic acid at about 75% humidity. Suitable genetic modifications for improving barrier function includes transfection with a DNA construct capable of expressing GKLF.Type: GrantFiled: March 1, 2002Date of Patent: December 13, 2005Assignee: Stratech CorporationInventors: Allen Comer, Lynn Allen-Hoffmann, Michael Hoffmann

Patent number: 6733530Abstract: Autologous cultured keratinocytes are grown on a biosynthetic and biocompatible substratum following pre-seeding with autologous or allogenic dermal fibroblasts. The resultant composite material may then be applied on the neodermis of artificial skin which had been previously engrafted on the patient. The composite material, and specifically Composite Biocompatible Skin Graft (CBSG) material comprises autologous keratinocytes A and allogenic or autologous dermal fibroblasts grown on an artificial skin. A method for cultivating the CBSG includes the application of dermal fibroblasts onto the substratum as a feeder layer and then the inoculation of autologous keratinocytes on the resultant structure. A method for engraftment comprises first applying an artificial skin with a protective silicone membrane on a wound area, thereby allowing vascularization; and following vascularization, removing the silicone membrane and engrafting the CBSG material onto the vascularized artificial skin.Type: GrantFiled: August 2, 1999Date of Patent: May 11, 2004Inventors: Ping Kuen Lam, Eric Sun-Yin Chan

Publication number: 20030195625Abstract: A synthetic or natural human hair end is encapsulated with a biodegradable implantable material, to form an artificial follicle suitable for implantation. The biodegradable material can be programmed to be reabsorbed by the body in a predetermined term of time. Once the material is substantially absorbed by the body the hair shaft will lose its anchor hold into the derma. The degenerated hair will shed by simply combing or washing the hair. The created artificial hair must be implanted individually to create a natural appearance.Type: ApplicationFiled: April 15, 2002Publication date: October 16, 2003Inventors: Marco A.

Publication number: 20020198597Abstract: A device for eyelash replacement is described having a band portion, having at least one layer front outer layer of material simulating human skin on a first side of the band, the band having a second side opposite from the first said, the second side being removeably adherable to at least a portion of a user's upper or lower eyelid. A plurality of follicles is coupled to the layer of the band and the band is affixed to a user by adhering the band portion second side to a user's eyelid. A method is also described for affixing a hair follicle having a near end and a distal end to a band having at least one layer of simulated human skin. The method involves perforating the layer of simulated human skin so as to create an aperture having a pre-determined diameter, inserting the follicle near end through the aperture such that a length of follicle is under the layer, and, knot-tying the length of the follicle near end into a knot of a size diametrically larger than the diameter of the aperture.Type: ApplicationFiled: April 18, 2002Publication date: December 26, 2002Inventor: Yvonne Godfrey
