Abstract

Manifold structures, systems, and methods are disclosed that include using longitudinal members and one or more shaped projections to cause microstrain at a tissue site. In one instance a manifold structure includes a plurality of spaced longitudinal members and at least one shaped projection coupled to at least one of the plurality of longitudinal members for creating a microstrain at a tissue site. The at least one shaped projection includes a columnar member having a distal end and includes an enlarged member positioned at the distal end of the columnar member. The columnar member has a first outer diameter (D 1 ) and the enlarged member has a second outer diameter (D 2 ). The second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D 2 >D 1 ). Other systems, methods, and structures are presented.

First claim

We claim:

1 . A reduced-pressure wound treatment system for treating a tissue site on a patient, the system comprising:
a manifold structure for disposing proximate the tissue site, the manifold structure configured to deform more in a first direction than in a second direction upon being subjected to a reduced pressure, the manifold structure comprising:
a plurality of spaced longitudinal members, and
at least one shaped projection coupled to at least one of the spaced longitudinal members for creating a microstrain at the tissue site, the at least one shaped projection comprising a columnar member having a distal end and an enlarged member positioned at the distal end of the columnar member;
a sealing member for placing over the tissue site and the manifold structure and operable to form a fluid seal over the tissue site and the manifold structure; and a reduced-pressure subsystem for delivering reduced pressure to the sealing member.

2 . The system of claim 1 , wherein the spaced longitudinal members are substantially parallel with one another.

3 . The system of claim 1 , wherein the first direction and the second direction are substantially coplanar.

4 . The system of claim 1 , wherein at least one of the spaced longitudinal members includes two or more shaped projections for creating a microstrain at the tissue site.

5 . The system of claim 1 , wherein the spaced longitudinal members are interconnected by a plurality of lateral interconnecting members.

6 . The system of claim 1 , further comprising a plurality of lateral interconnecting members, wherein the lateral interconnecting members are coupled to the plurality of spaced longitudinal members.

7 . The system of claim 1 , wherein the columnar member has a first outer diameter (D 1 ), wherein the enlarged member has a second outer diameter (D 2 ), and wherein the second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D 2 >D 1 ).

8 . A manifold structure for treating a tissue site on a patient, the manifold structure comprising:
a plurality of spaced longitudinal members; at least one shaped projection coupled to at least one of the spaced longitudinal members for creating a microstrain at the tissue site, the at least one shaped projection comprising a columnar member having a distal end and an enlarged member positioned at the distal end of the columnar member; and wherein the manifold structure is configured to deform more in a first direction than in a second direction upon being subjected to a reduced pressure.

9 . The manifold structure of claim 8 , wherein the spaced longitudinal members are substantially parallel with one another.

10 . The manifold structure of claim 8 , wherein the first direction and the second direction are substantially coplanar.

11 . The manifold structure of claim 8 , wherein at least one of the spaced longitudinal members includes two or more shaped projections for creating a microstrain at the tissue site.

12 . The manifold structure of claim 8 , wherein the spaced longitudinal members are interconnected by a plurality of lateral interconnecting members.

13 . The manifold structure of claim 8 , further comprising a plurality of lateral interconnecting members, wherein the lateral interconnecting members are coupled to the plurality of spaced longitudinal members.

14 . The manifold structure of claim 8 , wherein the columnar member has a first outer diameter (D 1 ), wherein the enlarged member has a second outer diameter (D 2 ), and wherein the second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D 2 >D 1 ).

15 . The manifold structure of claim 8 , wherein the manifold structure is deformable.

16 . The manifold structure of claim 8 , wherein the enlarged member has a spherical shape.

17 . The manifold structure of claim 8 , wherein the plurality of spaced longitudinal members of the manifold structure are adapted to move laterally towards one another to deform the manifold structure in the first direction, the first direction being substantially perpendicular to the spaced longitudinal members.
