  • Patent number: 6348069
    Abstract: It has been discovered that improved yields of engineered tissue following implantation, and engineered tissue having enhanced mechanical strength and flexibility or pliability, can be obtained by implantation, preferably subcutaneously, of a fibrous polymeric matrix for a period of time sufficient to obtain ingrowth of fibrous tissue and/or blood vessels, which is the removed for subsequent implantation at the site where the implant is desired. The matrix is optionally seeded prior to the first implantation, after ingrowth of the fibrous tissue, or at the time of reimplantation. The time required for fibrous ingrowth typically ranges from days to weeks. The method is particularly useful in making valves and tubular structures, especially heart valves and blood vessels.
    Type: Grant
    Filed: November 3, 1998
    Date of Patent: February 19, 2002
    Assignee: Children's Medical Center Corporation
    Inventors: Joseph P. Vacanti, Christopher K. Breuer, Beverly E. Chaignaud, Toshiraru Shin'oka
