Abstract

A homograft implant is made from prepackaged, processed homograft material. The homograft material is taken in its purchased dehydrated form and cut into strips of varying shapes and sized. The strips are then adhesively secured together in a laminar manner by a tissue adhesive to form the desired shape and density of the implant. Once the implant has been made, it may then be surgically implanted in a desired location, immediately beneath the patient'"'"'s dermis so as to alter the exterior appearance of the patient at the implant site. Since the implant is formed of dehydrated homograft material, endogenous tissue readily attaches to the implant after a short period of time, so that the implant becomes integral with the body.

Claims

1. A method of altering the appearance of a person'"'"'s physical features, comprising:

forming an implant of a desired shape of two or more layers of stiff, but formable thin tissue, dehydrated homograft; and

inserting said implant immediately beneath the person'"'"'s dermis in a desired location.

2. The method of claim 1, wherein said forming step includes gluing adjacent tissue layers to each other with tissue glue.

3. The method of claim 1, including the step of shaping said implant to conform to the shape of the portion of the person where the implant is to be positioned.

4. The method of claim 1, including cutting said layers in a desired shape from a larger section of said homograft tissue and stacking said layers to form a laminated implant with each layer being glued to the adjacent layers.

5. The method of claim 1, wherein said homograft tissue is made of dura mater.

6. The method of claim 1, wherein said homograft tissue is made of fascia muscle lining.

7. The method of claim 1, wherein said homograft tissue is made of a collagen matrix.

8. The method of claim 1, wherein said inserting step further comprises:

cutting an opening smaller than the size of said implant;

endwise inserting said implant through said opening; and

guiding said implant to said desired location.

9. A method of altering the appearance of a person'"'"'s nose comprising:

cutting two or more thin, stiff layers of dehydrated dura mater;

stacking and gluing the layers together with tissue glue to form an integral implant;

shaping said implant into the shape necessary to create the desired alteration in appearance;

forming an incision inside the nasal cavity; and

inserting said implant through the incision to the desired position in the nose directly beneath the persons dermis.
