The invention is directed to methods and devices for the reconstruction,
repair, augmentation or replacement of laminarily organized organs or
tissue structures in a patient in need of such treatment. The device
comprises a biocompatible synthetic or natural polymeric matrix shaped to
conform to at least a part of the luminal organ or tissue structure with
a first cell population on or in a first area and a second cell
population such as a smooth muscle cell population in a second area of
the polymeric matrix. The method involves grafting the device to an area
in a patient in need of treatment. The polymeric matrix comprise a
biocompatible and biodegradable material.
