SYSTEM AND METHOD FOR REPAIRING MUSCLE DEFECT
A space in a muscle wall is dilated by a plunger-based mechanism to break up fibrotic bands by divulsion. While the space is dilated a dynamic plug is advanced into it, with the plug expanding and contracting with the space.
1 . Method comprising:
providing a mesh body established by plural mesh strands, the mesh body being engaged with at least one strengthening member that is not a mesh strand;
deforming the mesh body to a first configuration in which the mesh body can be advanced into a hole in a body tissue;
advancing the mesh body into the hole; and
allowing the mesh body to assume a second configuration at least partially under influence of the strengthening member in which the mesh body expands to substantially fill the hole, the mesh body creating a scaffold-like structure with a leaf spring-like force to foster tissue ingrowth and promote tissue regeneration such that new vascular structures can be formed within the mesh while minimizing ingrowth into the mesh body of fibrotic scar tissue, the hole not being an inguinal canal hernia.
2 . The method of claim 1 , further comprising dilating the hole prior to advancing the mesh body into the hole.
3 . The method of claim 1 , wherein the mesh body is advanced into the hole using open surgery.
4 . The method of claim 1 , wherein the mesh body is advanced into the hole using endoscopic surgery.
5 . The method of claim 1 , wherein the mesh body is advanced into the hole using laparoscopic surgery.
6 . The method of claim 1 , wherein the mesh body is advanced into the hole using natural orifice surgery.
7 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's pelvis floor.
8 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's long extremity muscle.
9 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's heart.
10 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's heart septum.
11 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's abdominal wall.
12 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's diaphragm.
13 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's femoral canal.
14 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's liver.
15 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's kidney.
16 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's lung.
17 . The method of claim 1 , wherein the body tissue is defined at least in part by a patient's pancreas.
18 . The method of claim 1 , wherein the mesh body is petal-shaped.
19 . Method comprising:
providing a mesh body established by plural mesh strands;
deforming the mesh body to a first configuration in which the mesh body can be advanced into a hole in a body tissue;
advancing the mesh body into the hole; and
allowing the mesh body to assume a second configuration in which the mesh body expands to substantially fill the hole, the mesh body creating a scaffold-like structure with a leaf spring-like force to foster tissue ingrowth and promote tissue regeneration such that new vascular structures can be formed within the mesh while minimizing ingrowth into the mesh body of fibrotic scar tissue, wherein the body tissue is defined at least in part by a patient's long extremity muscle, or by a patient's heart, or by a patient's abdominal wall, or by a patient's diaphragm, or by a patient's femoral canal, or by a patient's liver, or by a patient's kidney, or by a patient's lung, or by a patient's pancreas.
20 . The method of claim 19 , wherein the mesh body includes plural petal-shaped lobes.
