General Description

[0021] An implant 20 is illustrated schematically in FIGS. 1 and 2. The implant 20 includes a support structure or matrix 22 (FIG. 2) which may have any desired configuration. A plurality of viable cells 24 (FIG. 2) are positioned on the support structure 22. Although the support structure 22 has been illustrated schematically in FIGS. 1 and 2 as having a rectangular configuration and the viable cells 24 have been illustrated schematically as being disposed in a rectangular array on a rectangular matrix, it is contemplated that the support structure 22 could have any desired configuration and that the viable cells 24 could be disposed in any desired arrangement on the support structure.

[0022] In accordance with one of the features of the present invention, one or more blood vessels 28 are connected with the support structure 22 to provide for a flow of blood through the support structure. Although the support structure 22 may be connected with blood vessels 28 ...

Abstract

An improved method of implanting cells in the body of a patient includes positioning viable cells on a support structure. One or more blood vessels may be connected with the support structure to provide a flow of blood through the support structure. A support structure may be positioned at any desired location in a patient's body. The support structure may be configured to replace an entire organ or a portion of an organ. An organ or portion of an organ may be removed from a body cells and / or other tissue is removed to leave a collagen matrix support structure having a configuration corresponding to the configuration of the organ or portion of an organ. Alternatively, a synthetic support structure may be formed. The synthetic support structure may have a configuration corresponding to a configuration of an entire organ or only a portion of an organ.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 457,100, filed Jun. 6, 2003. The '100 Application claimed the benefit under 35 U.S.C. §119(e) of Provisional Application No. 60 / 387,013 filed Jun. 7, 2002.BACKGROUND OF THE INVENTION [0002] The present invention relates to the implanting of cells into a body of a patient, and in particular to the implantation of viable cells on a scaffold or support structure. [0003] Various organs or other tissue in a patient's body may become defective due to trauma, disease, or other causes. Transplanting of organs and / or tissue has been utilized for the treatment of defective organs. However, problems have been encountered in securing an adequate number of suitable donor organs. It is believed that it may be desirable to have a patient grow a replacement organ, portion of an organ, or other body tissue for replacement of any defective tissue, organ, or portion thereof.
