Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods include a sealing ring that helps form a fluid seal around the linear wound. In one instance, a sealing material is extruded around the linear wound to help form a seal. In another instance, a sealing ring is coupled to a lower portion of a dressing bolster to form a seal. Other systems, methods, and apparatuses are disclosed.

1. A system for treating a linear wound on a patient, the system comprising: a dressing assembly, the dressing assembly comprising: a dressing bolster having a first side and a second, inward-facing side,a comfort layer coupled to the second, inward-facing side of the dressing bolster,a first sealing member portion covering the dressing bolster,a second sealing member portion covering a portion of the second, inward-facing side of the dressing bolster and extending outward from the dressing bolster to form a drape extension, wherein a portion of the first sealing member is coupled to the second sealing member,a sealing ring disposed adjacent to the second, inward-facing side of the dressing bolster, andwherein the first sealing member portion, second sealing member portion, and sealing ring form a sealed space over the linear wound; anda reduced-pressure source for fluidly coupling to the sealed space. 2. The system of claim 1, wherein the sealing ring is formed from a sealing material having a hardness in the range of 70-80 Shore (type OO). 3. The system of claim 1, wherein the sealing ring has a thickness Tsr that is in the range 0.7-1.25 mm. 4. The system of claim 1, wherein the sealing ring has a thickness Tsr, the second sealing member portion has a thickness Tsm, and the ratio of Tsr/Tsm is in the range of about 2.7 to 7.0. 5. The system of claim 1, wherein the sealing ring comprises a sealing material laminated onto a drape ring and further comprising an adhesive coupling the drape ring to the comfort layer or to the dressing bolster. 6. The system of claim 1, wherein the dressing bolster comprises at least two discrete members placed with abutting edges and wherein the sealing ring comprises at least two discrete members that have coalesced to form an integral member. 7. The system of claim 1, wherein the sealing ring comprises a sealing material, and wherein the sealing material comprises at least one of the following: hydrocolloids, hydrogels, silicone polymers, and natural gums (xanthan, guar, cellulose). 8. The system of claim 1, wherein the dressing bolster has lateral edges formed at an angle other than 90 degrees with respect to the second, inward-facing side of the dressing bolster. 9. The system of claim 1, wherein the dressing bolster has lateral edges formed at an angle between 20 to 50 degrees with respect to the second, inward-facing side of the dressing bolster. 10. The system of claim 1, wherein the sealing ring is coupled to at least a portion of the second, inward-facing side of the comfort layer. 11. The system of claim 1, wherein the sealing ring is coupled to at least a portion of the second sealing member portion. 12. The system of claim 1, wherein the sealing ring extends beyond a lateral edge of the dressing bolster. 13. A method for treating a linear wound on a patient with reduced pressure, the method comprising: extruding a sealing material around the linear wound to form a sealing ring;disposing a dressing bolster proximate to the linear wound and coupled to at least a portion of the sealing material;covering the dressing bolster and a portion of the patient's epidermis with a sealing member to create a sealed space; anddelivering reduced pressure to the sealed space. 14. The method of claim 13, wherein the sealing material has a hardness in the range of 70-80 Shore (type OO). 15. The method of claim 13, wherein the sealing ring has a thickness Tsr that is in the range 0.7-1.25 mm. 16. The method of claim 13, wherein the sealing ring has a thickness Tsr, the sealing member has a thickness Tsm, and the ratio of Tsr/Tsm is in the range of about 2.7 to 7.0. 17. The method of claim 13, wherein the sealing material comprises at least one of the following: hydrocolloids, hydrogels, silicone polymers, and natural gums (xanthan, guar, cellulose). 18. A method for treating a linear wound of a patient with reduced pressure, the method comprising: disposing a bolster assembly proximate to the linear wound, wherein the bolster assembly comprises: a dressing bolster having a first side and a second, inward-facing side,a comfort layer coupled to the second, inward-facing side of the dressing bolster, anda sealing ring coupled to the second, inward-facing side of the comfort layer;covering the bolster assembly with a sealing member to form a sealed space containing the dressing assembly; andintroducing reduced pressure into the sealed space. 19. The method of claim 18, wherein the sealing ring extends beyond a lateral edge of the dressing bolster. 20. The method of claim 18, wherein the sealing material has a hardness in the range of 70-80 Shore (type OO). 21. The method of claim 18, wherein the sealing ring has a thickness Tsr that is in the range 0.7-1.25 mm. 22. The method of claim 18, wherein the sealing ring has a thickness Tsr, the sealing member has a thickness Tsm, and the ratio of Tsr/Tsm is in the range of about 2.7 to 7.0. 23. The method of claim 18, wherein the sealing material comprises at least one of the following: hydrocolloids, hydrogels, silicone polymers, and natural gums (xanthan, guar, cellulose). 24. The method of claim 18, wherein the dressing bolster comprises a first dressing bolster having a first end and a second dressing bolster having a first end; andwherein the step of disposing the bolster assembly comprises disposing the first dressing bolster over at least a portion of the linear wound and disposing the second dressing bolster over at least a portion of the linear wound, wherein the first end of the first dressing bolster abuts the first end of the second dressing bolster. 25. The method of claim 18, wherein the dressing bolster comprises a first dressing bolster having a first end and a second dressing bolster having a first end;wherein the step of disposing the bolster assembly comprises disposing the first dressing bolster over at least a portion of the linear wound and disposing the second dressing bolster over at least a portion of the linear wound, wherein the first end of the first dressing bolster abuts the first end of the second dressing bolster;wherein the sealing ring comprises a first sealing ring and a second sealing ring;wherein the first sealing ring is coupled to the first dressing bolster and the second sealing ring is coupled to the second dressing bolster; andwherein the first sealing ring and second sealing ring touch and become an integral sealing ring. 26. A system for treating a linear wound on a patient comprises: a dressing bolster assembly comprising: a dressing bolster having a first side and a second, inward-facing side,a comfort layer coupled to the second, inward-facing side of the dressing bolster, wherein the comfort layer has a first side and a second, inward-facing side, anda sealing ring coupled to the second, inward-facing side of the comfort layer;a sealing member disposed over the dressing bolster for creating a sealed space; anda reduced-pressure source fluidly coupled to the sealed space.
