Improved prostheses comprising a tissue expander and a graft material are disclosed herein. Also disclosed are methods of making prostheses and methods of treatment using the prostheses.

Implantable prosthesis having acellular tissue attachments

The present disclosure provides tissue fillers. The tissue fillers can include a plurality of tissue particles formed from acellular tissue matrix fragments. The tissue fillers can be used to fill tissue sites, such as voids formed after tissue resection.

Flowable tissue products

Methods for treating tissue matrices and tissue matrices produced according to the methods are provided. The methods can include treating a tissue matrix with a proteolytic enzyme to produce a desired pliability of the tissue matrix and/or to control the immunogenicity of the tissue matrix. The methods can also comprise performing an assay to determine if contacting the at least one collagen-containing tissue matrix with a proteolytic enzyme has altered the at least one collagen-containing tissue matrix to reduce a human immune response to the tissue matrix. The methods can comprise treatment with alcalase under conditions controlled to produce a desired pliability without unacceptable alteration in collagen structure.

Method for enzymatic treatment of tissue products

A prosthesis comprising a tissue expander and one or more samples of graft material, wherein the tissue expander is attached to the one or more samples of graft material in a manner that allows the tissue expander and the one or more samples of graft material to be implanted in a patient as a unitary prosthesis; and wherein tissue expander is attached to the one or more samples of graft material in a manner that will allow the tissue expander and the graft material to separate after a period of time following implantation to allow removal of the tissue expander from an implant sites while leaving the graft material within the implant site, the prosthesis comprises a tissue expander having molded grooves, slots, channels, or other shallow cavity spaces on a surface, and wherein the graft material is within the grooves, slots, channels, or other shallow cavity spaces, securing the graft material to the tissue expander.

The present disclosure provides tissue fillers. The tissue fillers can include a plurality of tissue particles formed from acellular tissue matrix fragments. The tissue fillers can be used to fill tissue sites, such as voids formed after tissue resection. The disclosure also includes methods of treating tissue using the tissue fillers. The tissue particles can each be formed of tissue fragments having certain sizes.
