TISSUE MATRICES AND METHODS OF TREATMENT
Methods and devices for treatment of tissues are provided. The methods can be used to interlock a composition with tissue for protection or engagement of the tissue. The devices can be used to treat a number of treatment sites, for example, to provide structural support to injured or surgically altered tissues and/or to secure tissues and/or implants in place.
1 . A method of treatment, comprising:
providing a composition, the composition including (i) a composition body, (ii) at least a first component formed in the composition body, and (iii) at least a second component formed in the composition body, the first and second components being complementary relative to each other and configured to interlock relative to each other or tissue, the composition comprising at least one of a tissue matrix or a synthetic material;
at least partially wrapping the composition around or positioning the composition onto the tissue or an implant; and
interlocking the first component with the second component relative to each other or the tissue to maintain the composition at least partially wrapped around or positioned on the tissue or the implant.
2 . The method of claim 1 , wherein the first component comprises an opening passing through the composition body.
3 . The method of claim 1 , wherein the first component comprises one or more holes or slits passing through the composition body.
4 . The method of claim 1 , wherein the second component comprises flared sections extending on opposing sides of the composition body.
5 . The method of claim 4 , comprising passing the flared sections through an opening in the composition body in a first direction, wherein the flared sections are shaped to prevent passage of the flared sections through the opening in the composition body in a second direction opposing the first direction.
6 . The method of claim 1 , wherein the second component comprises a tab including two opposing extensions along a length of the composition body.
7 . The method of claim 6 , comprising bending the two opposing extensions of the tab into a non-extending configuration and passing the two opposing extensions through a hole or slit in the composition body in a first direction.
8 . The method of claim 7 , comprising unbending the two opposing extensions after passage of the two opposing extensions through the hole or slit in the composition body, wherein the two opposing extensions prevent passage of the two opposing extensions through the hole or slit in the composition body in a second direction opposing the first direction.
9 . (canceled)
10 . (canceled)
11 . The method of claim 1 , wherein interlocking the first component and the second component to the tissue comprises passing a portion of tissue through the first component and passing at least a portion of the second component through an incision in the tissue.
12 . A composition for tissue treatment, comprising:
a composition body;
at least a first component formed in the composition body; and
at least a second component formed in the composition body;
wherein the composition is configured to be at least partially wrapped around or positioned onto tissue or an implant,
wherein the composition comprises at least one of a tissue matrix or a synthetic material, and
wherein the first and second components are complementary relative to each other and are configured to interlock relative to each other or to the tissue to maintain the composition at least partially wrapped around or positioned on the tissue or the implant.
13 . The composition of claim 12 , wherein the tissue matrix is an acellular tissue matrix.
14 . The composition of claim 13 , wherein the tissue matrix is a dermal tissue matrix.
15 . The composition of claim 12 , wherein the composition body is flexible to permit at least partially wrapping the composition body around the tissue or the implant, and interlocking of the first and second components relative to each other.
16 . The composition of claim 12 , wherein the first component comprises one or more openings passing through the composition body.
17 . The composition of claim 12 , wherein the first component comprises one or more holes or slits passing through the composition body.
18 . The composition of claim 12 , wherein the second component comprises flared sections extending on opposing sides of the composition body.
19 . The composition of claim 18 , wherein the flared sections are configured for passage through an opening in the composition body in a first direction, and the flared sections are shaped to prevent passage of the flared sections through the opening in the composition body in a second direction opposing the first direction.
20 . The composition of claim 12 , wherein the second component comprises a tab including two opposing extensions along a length of the composition body, wherein the two opposing extensions are configured to be bent into a non-extending configuration to pass the two opposing extensions through a hole or slit in the composition body in a first direction, and wherein the two opposing extensions are configured to be unbent after passage of the two opposing extensions through the hole or slit in the composition body to prevent passage of the two opposing extensions through the hole or slit in the composition body in a second direction opposing the first direction.
21 . The composition of claim 12 , wherein the first and second components are configured to remain interlocked relative to each other or the tissue without the use of suture.
22 . A method of treatment, comprising:
providing a composition, the composition including (i) a composition body, and (ii) two components formed in the composition body, each of the two components being configured to interlock relative to tissue, the composition comprising at least one of a tissue matrix or a synthetic material;
at least partially wrapping the composition around or positioning the composition onto the tissue; and
interlocking each of the two components with the tissue to maintain the composition at least partially wrapped around or positioned on the tissue.
