Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster and a sealing ring. The sealing ring may be adapted to provide a fluid seal around the tissue site, and to absorb fluids from the tissue site. In some embodiments, the sealing ring may be extruded around the tissue site. In other embodiments, the sealing ring may be coupled to the dressing bolster. Other systems, apparatuses, and methods are disclosed.

1. A dressing assembly, comprising: a dressing bolster comprising foam and having a first side and a second side;a comfort layer having a first side and a second side, the first side of the comfort layer coupled to the second side of the dressing bolster;a sealing ring comprising an absorbent and having a first side and a second side, the first side of the sealing ring coupled to the second side of the comfort layer and positioned around a circumference of the dressing bolster, at least a portion of the second side of the comfort layer being exposed; anda removable bottom release member having a release agent configured to contact the sealing ring and comprising a polar semi-crystalline polymer configured to resist deformation when positioned in contact with the second side of the sealing ring. 2. The dressing assembly of claim 1, wherein the sealing ring comprises a hydrocolloid including the absorbent. 3. The dressing assembly of claim 1, wherein the absorbent comprises carboxy methyl cellulose. 4. The dressing assembly of claim 1, wherein the dressing bolster has a lateral edge substantially aligned with a lateral edge of the comfort layer. 5. The dressing assembly of claim 1, wherein the sealing ring is positioned at a lateral edge of the dressing bolster. 6. The dressing assembly of claim 1, wherein the portion of the second side of the comfort layer that is exposed is configured to be positioned directly against the tissue site, the sealing ring being configured to surround the tissue site and the portion of the comfort layer that is exposed. 7. The dressing assembly of claim 1, wherein the sealing ring is comprised of a sealing material having a hardness between about 70 to about 80 Shore, type OO. 8. The dressing assembly of claim 1, wherein the sealing ring has a thickness Tsr between about 0.7 millimeters to about 1.25 millimeters. 9. The dressing assembly of claim 1, wherein the sealing ring extends beyond a lateral edge of the dressing bolster and a lateral edge of the comfort layer, the dressing assembly further comprising a release member in contact with at least a portion of the first side of the sealing ring beyond the lateral edge of the dressing bolster and the lateral edge of the comfort layer. 10. The dressing assembly of claim 1, wherein the dressing bolster is comprised of a reticulated open-cell foam. 11. The dressing assembly of claim 1, wherein the comfort layer is selected from the group consisting of a woven material, a non-woven material, a polyester knit material, and a fenestrated film. 12. The dressing assembly of claim 1, wherein the dressing bolster has longitudinal cuts and lateral cuts disposed in the first side of the dressing bolster, the longitudinal cuts positioned normal to the lateral cuts. 13. The dressing assembly of claim 1, wherein the bottom release member is configured to cover the sealing ring and to be removable from the sealing ring. 14. The dressing assembly of claim 13, wherein the bottom release member is comprised of polyethylene terephthalate. 15. A method for treating a tissue site, comprising: providing a dressing assembly, comprising: a dressing bolster,a comfort layer coupled to the dressing bolster,a sealing ring coupled to the comfort layer, anda bottom release member having a release agent configured to contact the sealing ring and comprising a polar semi-crystalline polymer positioned in contact with the sealing ring and configured to resist deformation;removing the bottom release member;disposing the dressing assembly proximate to the tissue site;covering the dressing assembly with a sealing member to form a sealed space between the dressing assembly and the tissue site;extracting fluid from the tissue site into the dressing assembly; andabsorbing the fluid from the tissue site into the sealing ring. 16. The method of claim 15, wherein extracting the fluid comprises applying reduced pressure to the sealed space. 17. The method of claim 15, further comprising communicating the fluid in a lateral direction within the dressing assembly toward the sealing ring. 18. The method of claim 15, further comprising wicking the fluid in a lateral direction within the dressing assembly toward the sealing ring. 19. The method of claim 15, wherein the sealing ring comprises an absorbent. 20. The method of claim 15, wherein the sealing ring comprises a hydrocolloid including an absorbent. 21. The method of claim 19, wherein the absorbent comprises carboxy methyl cellulose. 22. The method of claim 15, wherein the sealing ring is positioned at a lateral edge of the dressing bolster and configured to surround the tissue site. 23. The method of claim 15, wherein the sealing ring is positioned around at least a portion of the comfort layer that is exposed and configured to be positioned directly against the tissue site.
