Scaffold and method for implanting cells
First Claim
1. A method of implanting cells into a body of a patient, said method comprising the steps of:
- providing a support structure,harvesting a polysaccharide-based modified biofilm from bacteria,attaching viable cells for implantation to the support structure with the polysaccharide-based modified biofilm, andconnecting one portion of a blood vessel in the patient'"'"'s body with a first portion of the support structure, and connecting another portion of a blood vessel in the patient'"'"'s body with a second portion of the support structure.

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.

65. A method of implanting cells into a body of a patient, said method comprising the steps of providing a plurality of support structures, preparing a polysaccharide-based modified biofilm from bacteria;
- attaching viable cells for implantation on each of the support structures with the polysaccharide-based modified biofilm, forming a plurality of openings in an organ in the patient'"'"'s body, and positioning the plurality of support structures in the plurality of openings in the organ in the patient'"'"'s body with the viable cells disposed on the support structures.
- 66. A method of implanting cells into a body of a patient, said method comprising the steps of removing an organ from a body, removing cells from the organ which is removed from the body to leave a support structure having a configuration corresponding to the configuration of the organ, preparing a polysaccharide-based modified biofilm from bacteria positioning viable cells for implantation on the support structure having a configuration corresponding to the configuration of the organ which is removed from a body, attaching the viable cells to the support structure with the polysaccharide-based modified biofilm, and positioning the support structure in the patient'"'"'s body with the viable cells disposed on the support structure.
-
92. A method of implanting cells into a body of a patient, said method comprising the steps of removing a portion of an organ from a body, rendering the portion of an organ which is removed from the body non-antigenic to leave a support structure having a configuration corresponding to the configuration of the portion of an organ, preparing a polysaccharide-based modified biofilm from bacteria, attaching viable cells for implantation with the polysaccharide-based modified biofilm onto the support structure having a configuration corresponding to the configuration of the portion of an organ which is removed from a body, and positioning the support structure in the patient'"'"'s body with the viable cells disposed on the support structure.
- 93. A method of implanting cells into a body of a patient, said method comprising the steps of removing a portion of a blood vessel from the patient'"'"'s body, providing a tubular support structure, preparing a polysaccharide-based modified biofilm from bacteria, attaching viable cells for implantation with the polysaccharide-based modified biofilm onto the tubular support structure, connecting a first end portion of the tubular support structure with the blood vessel from which a portion was removed, and conducting a flow of blood between the tubular support structure and the blood vessel from which a portion was removed.

105. A method of implanting cells into a body of a patient, said method comprising the steps of:
-
providing a support structure containing a barrier being impervious to blood flow, the barrier being formed separately from the support structure and mounted in the support structure; preparing a polysaccharide-based modified biofilm from bacteria attaching viable cells for implantation onto the support structure adjacent the impervious barrier with the polysaccharide-based modified biofilm; positioning the support structure in the patient'"'"'s body with the viable cells disposed on the support structure; and directing a flow of blood throughout the support structure with the impervious barrier to supply said viable cells with the blood. - View Dependent Claims (106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116)

117. A method of implanting cells into a body of a patient, said method comprising the steps of:
-
shaping a support structure to have an external configuration corresponding to an external configuration of at least a portion of a selected organ, the support structure having a barrier disposed thereon, the barrier being impervious to blood flow; preparing a polysaccharide-based modified biofilm from bacteria; attaching viable cells for implantation with the polysaccharide-based modified biofilm onto the support structure, the viable cells positioned on opposite sides of the impervious barrier; removing at least a portion of the selected organ from the patient'"'"'s body; positioning the support structure in the patient'"'"'s body at the location where at least a portion of the selected organ was removed from the patient'"'"'s body; and dispersing the blood flow throughout the support structure with the barrier. - View Dependent Claims (118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131)
