TISSUE MATRICES AND METHODS OF TREATMENT
Methods, systems, and compositions for treatment are provided. The methods can be used to stretch and completely or nearly completely wrap a composition around an implant or tissue expander. The systems can be used to protect an implant or tissue expander by completely or nearly completely wrapping a composition around the implant or tissue expander. The compositions can be used to completely or nearly completely wrap around an implant or tissue expander to provide support and protection to the implant or tissue expander.
1 . A composition for treatment, comprising:
a composition body; and
a mesh pattern formed in at least a portion of the composition body;
wherein the composition body comprises a tissue matrix or synthetic material; and
wherein the composition body is configured to stretch and expand at the mesh pattern to completely or nearly completely wrap the composition body around or position the composition body onto an implant or a tissue expander.
2 . The composition of claim 1 , wherein the tissue matrix is an acellular tissue matrix.
3 . The composition of claim 1 , wherein the composition body comprises a central region and at least two extensions protruding from opposing sides of the central region, the at least two extensions having the mesh pattern formed therein.
4 . The composition of claim 3 , wherein the composition body is configured to be positioned onto the implant or tissue expander with the central region of the composition body disposed against an anterior side of the implant or tissue expander.
5 . The composition of claim 4 , wherein the at least two extensions are configured to be stretched and expanded at the mesh pattern to wrap the composition body around the implant or tissue expander such that one extension of the at least two extensions is wrapped in a first direction around the implant or tissue expander and another extension of the at least two extensions is wrapped in an opposing direction to secure the composition body to the implant or tissue expander.
6 . The composition of claim 5 , wherein the at least two extensions are configured to be engaged with each other at a posterior side of the implant or tissue expander, the posterior side opposing the anterior side of the implant or tissue expander.
7 . The composition of claim 3 , wherein the composition body comprises at least two additional extensions protruding form opposing sides of the central region.
8 . The composition of claim 4 , wherein the at least two additional extensions each comprise a mesh pattern formed therein.
9 . The composition of claim 3 , wherein the central region comprises the mesh pattern formed therein.
10 . The composition of claim 1 , wherein the tissue matrix is a tissue matrix sheet defining a planar and flexible configuration.
11 . The composition of claim 3 , comprising a fastening element configured to interlock the at least two extensions relative to each other to secure the composition body to the implant or tissue expander.
12 . The composition of claim 1 , wherein the composition body comprises a top region, a central region, and a bottom region, at least one strap being integrally formed adjacent to an edge of the bottom region.
13 . The composition of claim 3 , wherein the at least two extensions extend parallel to each other.
14 . The composition of claim 11 , wherein the fastening element detachably interlocks the at least two extensions of the composition body.
15 . The composition of claim 11 , wherein the fastening element includes an elongated body with a proximal end and a distal end, the proximal end including a rounded tip.
16 . The composition of claim 15 , wherein a diameter of the rounded tip is dimensioned greater than a width of the elongated body.
17 . The composition of claim 16 , wherein the rounded tip includes a slit configured to receive therethrough the distal end of the fastening element to interlock the fastening element to the at least two extensions.
18 . The composition of claim 3 , wherein the central region of the composition body is mesh-free.
19 . The composition of claim 3 , wherein:
the composition body includes a horizontal axis passing through the central region, the at least two extensions protruding from the opposing sides of the central region and substantially parallel to the horizontal axis;
the composition body includes a vertical axis passing through the central region; and
the composition body includes two additional extensions protruding from opposing sides of the central region and substantially parallel to the vertical axis.
20 . A system for treatment, comprising:
a composition, the composition including (i) a tissue matrix or synthetic material defining a composition body, and (ii) a mesh pattern formed in at least a portion of the composition body; and
an implant or a tissue expander;
wherein the composition body is configured to stretch and expand at the mesh pattern to completely or nearly completely wrap the composition body around or position the composition body onto the implant or the tissue expander.
