WOUND TREATMENT DEVICE
The present disclosure provides devices for treating deep or tunneling wounds, such as fistulas. The device can include a regenerative tissue matrix that can be tailored to a variety of different wound shapes and sizes, and can be secured in place to help regenerate tissue within the wound.
1 . A wound treatment device, comprising:
an elongated central body portion formed of a tissue matrix having a length and a width and a longitudinal axis extending along the length;
a group of tissue matrix bodies, wherein each of the tissue matrix bodies has a width that is wider than the width of the elongated central body portion, and wherein each of the tissue matrix bodies includes an opening passing there through, such that a portion of the elongated central body portion can be passed through each of the bodies to form an elongated structure having a central support formed of the elongated central body portion, and space filling protrusions formed by the group of tissue matrix bodies.
2 . The device of claim 1 , wherein the elongated central body portion is formed of an acellular tissue matrix.
3 . (canceled)
4 . The device of claim 1 , wherein the elongated central body portion comprises a tissue matrix derived from tissue selected from tendon, ligament, vascular tissue, neural tissue, muscle tissue, intestinal tissue, small intestine submucosal tissue, bladder tissue, hepatic tissue, lung tissue, or dural tissue.
5 . The device of claim 1 , wherein each of the tissue matrix bodies is formed of an acellular tissue matrix.
6 . (canceled)
7 . The device of claim 1 , wherein each of the tissue matrix bodies comprises a tissue matrix derived from tissue selected from tendon, ligament, vascular tissue, neural tissue, muscle tissue, intestinal tissue, small intestine submucosal tissue, bladder tissue, hepatic tissue, lung tissue, or dural tissue.
8 . The device of claim 1 , wherein the elongated central body portion and each of the tissue matrix bodies are joined to one another.
9 . The device of claim 8 , wherein the elongated central body portion and each of the tissue matrix bodies are formed of a single piece of material.
10 . The device of claim 1 , wherein the width of the elongated central body portion varies along the length of the elongated central body portion.
11 . The device of claim 10 , wherein the width of the elongated central body portion decreases from one end to a second end.
12 . The device of claim 1 , wherein the widths of the tissue matrix bodies vary.
13 . The device of claim 12 , wherein the tissue matrix bodies are connected to one another in a chain configuration, and wherein the width of the tissue matrix bodies decreases along a length of the chain configuration.
14 . The device of claim 1 , wherein the elongated central body portion has been passed through the opening in each of the tissue matrix bodies to form an elongated structure having a central load-bearing support and tissue matrix protrusions for treating a wound.
15 - 28 . (canceled)
29 . A method of treating a wound, comprising:
selecting a treatment device comprising:
an elongated central body portion formed of a tissue matrix having a length and a width and a longitudinal axis extending along the length; and
a group of tissue matrix bodies, wherein each of the tissue matrix bodies has a width that is wider than the width of the elongated central body portion, and wherein each of the tissue matrix bodies includes an opening passing there through, wherein a portion of the elongated central body portion passes through each of the tissue matrix bodies to form an elongated structure having a central support formed of the elongated central body portion, and space filling protrusions formed by the group of tissue matrix bodies; and
passing an end portion of the elongated central body portion through an opening in a wound, and moving the elongated central body portion into the opening until the space filling protrusions are positioned in a desired location within the wound.
30 . The method of claim 29 , wherein the wound comprises one or more of a tunneling wound, a fistula, and an anal fistula.
31 - 32 . (canceled)
33 . The method of claim 29 , wherein the elongated central body portion is formed of an acellular tissue matrix.
34 . (canceled)
35 . The method of claim 29 , wherein the elongated central body portion comprises a tissue matrix derived from tissue selected from tendon, ligament, vascular tissue, neural tissue, muscle tissue, intestinal tissue, small intestine submucosal tissue, bladder tissue, hepatic tissue, lung tissue, or dural tissue.
36 . The method of claim 29 , wherein each of the tissue matrix bodies is formed of an acellular tissue matrix.
37 . (canceled)
38 . The method of claim 29 , wherein each of the tissue matrix bodies comprises a tissue matrix derived from tissue selected from tendon, ligament, vascular tissue, neural tissue, muscle tissue, intestinal tissue, small intestine submucosal tissue, bladder tissue, hepatic tissue, lung tissue, or dural tissue.
39 . The method of claim 29 , wherein the elongated central body portion and each of the tissue matrix bodies are joined to one another.
40 . The method of claim 39 , wherein the elongated central body portion and each of the tissue matrix bodies are formed of a single piece of material.
41 . The method of claim 29 , wherein the width of the elongated central body portion varies along the length of the elongated central body portion.
42 . The method of claim 41 , wherein the width of the elongated central body portion decreases from one end to a second end.
43 . The method of claim 29 , wherein the widths of the tissue matrix bodies vary.
44 . The method of claim 43 , wherein the tissue matrix bodies are connected to one another in a chain configuration, and wherein the width of the tissue matrix bodies decreases along a length of the chain configuration.
