1) A implantable biodegradable device for providing a scaffolding for a trocar defect to promote wound healing, the trocar defect having a defect diameter, the fascia and associated layers around the trocar defect having a thickness, an outer layer and an inner layer, the outer layer being primarily fat and muscle, the inner layer being primarily peritoneum, the trocar defect at the bottom of a trocar tunnel, the device comprising:
A biodegradable inner scaffolding having a first base diameter, the inner scaffolding having a tissue facing surface; a biodegradable outer scaffolding having a tissue facing surface with a diameter, where the diameter is larger than the first base diameter but less than the trocar tunnel diameter, further comprising an inner ring and a perimeter; and a biodegradable coupling for detachably connecting the inner scaffolding with the outer scaffolding, the biodegradable coupling connected to the center of the tissue facing surface of the biodegradable inner scaffolding, the biodegradable coupling having an outer diameter, where the outer diameter of the biodegradable coupling is less than the inner diameter of the inner ring of the outer scaffolding,
wherein the length of the biodegradable coupling is sufficient to connect the biodegradable inner scaffolding to the biodegradable outer scaffolding, while allowing enough space between the biodegradable inner scaffolding and biodegradable outer scaffolding to maintain a predefined gap substantially equal to the thickness of the fascia. |
