First Claim
Patent Images
1. A biocompatible implant, comprising:
- a biocompatible scaffold; and
at least one tissue fragment that is associated with at least a portion of the scaffold, wherein the tissue fragment includes an effective amount of viable cells that can migrate out of the tissue fragment and populate the scaffold.

Abstract
A biocompatible tissue repair implant or scaffold device is provided for use in repairing a variety of tissue injuries, particularly injuries to cartilage, ligaments, tendons, and nerves. The repair procedures may be conducted with implants that contain a biological component that assists in healing or tissue repair. The biocompatible tissue repair implants include a biocompatible scaffold and particles of living tissue, such that the tissue and the scaffold become associated. The particles of living tissue contain one or more viable cells that can migrate from the tissue and populate the scaffold.

36. A method of treating living tissue, comprising:
-
providing a biocompatible scaffold;
providing a sample of tissue in the form of finely divided tissue fragments;
depositing the sample of tissue upon the biocompatible scaffold to form a tissue implant; and
implanting the tissue implant in a desired position relative to the tissue to be treated. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)

71. A method of preparing a tissue implant, comprising:
-
providing a bioimplantable scaffold;
obtaining a sample of tissue;
processing the sample of tissue under aseptic conditions to form at least one tissue fragment and a physiological buffering solution; and
depositing the tissue fragment on the bioimplantable scaffold to yield a tissue implant. - View Dependent Claims (72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95)

96. A method for measuring the effect of a substance on living tissue, comprising the steps of:
-
(a) creating a tissue construct by providing a biocompatible scaffold, obtaining a sample of tissue, processing the sample of tissue to form at least one tissue fragment, depositing the at least one tissue fragment on the biocompatible scaffold such that the at least one tissue fragment is associated with the biocompatible scaffold, thereby forming a tissue construct, and incubating the tissue construct for a duration and under conditions that are effective to allow cells within the tissue fragment to populate the scaffold;
(b) contacting the tissue construct with a substance; and
(c) determining the effects of the substance on the tissue construct. - View Dependent Claims (97)
