Method of augmenting tissue
A method of repairing tissue of a patient secures at least two sutures to two initial points of the patient, and couples sutures to a repair matrix comprising a scaffold portion and an expandable portion. The scaffold portion is configured to integrate over time with the tissue being repaired. The method also expands the expandable portion to urge the repair matrix against the tissue to produce a securing surface, and then secures the at least two sutures to two additional points of the patient. The at least two sutures traverse the securing surface of the repair matrix between the two initial points and the two additional points to secure the repair matrix to the patient.
1. A method of repairing tissue of a patient, the method comprising:
securing at least one suture to at least one initial point of the patient;
coupling the at least one suture to a repair matrix comprising a scaffold portion and an expandable portion, the scaffold portion configured to integrate over time with the tissue being repaired;
expanding the expandable portion to urge the repair matrix against patient tissue, expanding the expandable portion further producing a securing surface; and
securing the at least one suture to at least one additional point of the patient,
the at least one suture traversing the securing surface of the repair matrix between the at least one initial point and at least one additional point to secure the repair matrix to the patient,
wherein the expandable portion is configured to degrade within the patient, further wherein the scaffold portion is configured to integrate with the tissue faster than the expandable portion degrades within the patient.
2. The method of claim 1 wherein expanding causes the repair matrix to change shape toward a flatter configuration or a three-dimensional configuration.
3. The method of claim 1 wherein the at least one suture forms an X-pattern across the securing surface.
4. The method of claim 1 wherein securing the at least one suture to at least one additional point comprises securing the at least one suture to the one additional point with an anchor.
5. The method of claim 1 wherein expanding the expandable portion comprises directing a fluid through a tube and into the expanding portion.
6. The method of claim 1 wherein the expandable portion comprises an inflatable balloon.
7. The method of claim 1 wherein the scaffold portion comprises a collagen patch.
8. The method of claim 1 wherein the scaffold portion and expandable portion are integrated together.
9. The method of claim 1 wherein the scaffold portion and expandable portion are mechanically coupled together.
10. The method of claim 1 further comprising ejecting the repair matrix from an inserter, the repair matrix expanding after ejected.
