A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure
A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented.

1. A method of manufacturing a system for treating a linear wound on a patient, the method comprising the steps of: forming a closing dressing bolster for placing on the patient's epidermis over the linear wound, the closing dressing bolster comprising: a bolster body formed from a flexible closing
1. A method of manufacturing a system for treating a linear wound on a patient, the method comprising the steps of: forming a closing dressing bolster for placing on the patient's epidermis over the linear wound, the closing dressing bolster comprising: a bolster body formed from a flexible closing bolster material;wherein the bolster body comprises: a first closing member formed on a first lateral side of a central portion of the bolster body,a second closing member formed on a second lateral side of the central portion,wherein the first closing member has at least one surface formed with an oblique angle to a center plane between the first closing member and the second closing member, and wherein the second closing member has at least one surface formed with an oblique angle to the center plane, andwherein the first closing member and second closing member develop an inward closing force when the closing dressing bolster is placed under reduced pressure;providing an over-drape for placing over the closing dressing bolster;providing a reduced-pressure interface for fluidly coupling to the closing dressing bolster; andproviding a conduit for coupling the reduced pressure source and the reduced-pressure interface. 2. A method of treating a linear wound with reduced pressure, the method comprising the steps of: deploying a closing dressing bolster over the linear wound on the patient's epidermis, wherein the closing dressing bolster has a first closing member and a second closing member coupled together, and wherein the first closing member and second closing member are angled with respect to a longitudinal center plane that is between the first closing member and second closing member;deploying a sealing member over the closing dressing bolster and a portion of the patient's epidermis; anddelivering reduced pressure to the closing dressing bolster to cause the closing dressing bolster to develop an inward closing force. 3. The method of claim 2 the step of delivering reduced pressure to the closing dressing bolster creates a bending moment in the closing dressing bolster about the longitudinal center plane. 4. The method of claim 2, wherein the closing dressing bolster is formed from a translucent material. 5. The method of claim 2, wherein the closing dressing bolster is formed from a polymer having a stiffness of approximately durometer 50 Shore A. 6. The method of claim 2, wherein the closing dressing bolster is formed from a medical-grade silicone. 7. The method of claim 2, wherein the closing dressing bolster is formed with a gap between the first closing member and the second closing member, wherein a wicking material is disposed in the gap, and wherein the wicking material is sized and configured to be proximate to the linear wound when the closing dressing bolster is deployed. 8. The method of claim 1, wherein the closing dressing bolster is formed from a translucent material. 9. The method of claim 1, wherein the closing dressing bolster is formed from a polymer having a stiffness of approximately durometer 50 Shore A. 10. The method of claim 1, wherein the closing dressing bolster is formed from a medical-grade silicone. 11. The method of claim 1, wherein the closing dressing bolster is formed with a gap between the first closing member and the second closing member for receiving a wicking material. 12. A method of manufacturing a reduced-pressure system for treating a linear wound on a patient, the method comprising: forming a closing dressing bolster for placing on the patient's epidermis over the linear wound, the step of forming a closing dressing bolster comprises: forming a bolster body from a flexible closing bolster material,wherein the closing dressing bolster comprises a top wall and a bottom wall,coupling the top wall and bottom wall in a spaced relationship that forms a hollow region between the top wall and bottom wall, the bottom wall having a center portion, a first lateral portion, and a second lateral portion,forming at least one aperture in the top wall and at least one aperture in the bottom wall;forming a first closing member on the first lateral portion, andforming a second closing member on the second lateral portion,wherein the first closing member has at least one surface formed with an oblique angle to a center plane between the first closing member and the second closing member, andwherein the second closing member has at least one surface formed with an oblique angle to the center plane;forming a sealing subsystem for providing a seal over the closing dressing bolster and the patient;providing a reduced-pressure subsystem for delivering reduced pressure to the closing dressing bolster; andwherein the first closing member and second closing member are operable to move towards each other under reduced pressure to develop a closing force. 13. The method of claim 12, wherein the step of forming the bolster body further comprises: forming a wicking-material holder,disposing a wicking material in the wicking-material holder, andwherein the wicking material includes a flow path for removing fluids. 14. The method of claim 12, wherein the step of forming the closing dressing bolster comprises: forming a wicking material holder, andassociating a wicking material with the wicking-material holder, wherein the wicking-material holder and wicking material are sized and configured so that at least a portion of the wicking material is against the linear wound when a reduced pressure is applied and wherein the wicking material is operable under reduced pressure to remove fluids from the linear wound; andwherein the bolster body is formed from a see-through material and is operable to allow light to pass through sufficiently that color near the linear wound may be perceived from a point external to the system during use. 15. The system of a claim 12, wherein the bolster body is operable to allow light to pass through sufficiently that color of the linear wound may be seen from a point external to the system during use; andwherein the sealing subsystem comprises: an over-drape that extends over the closing dressing bolster, anda sealing apparatus for providing a seal between a patient's epidermis and the over-drape. 16. The method of claim 12, wherein the reduced-pressure subsystem comprises: a reduced-pressure source for providing reduced pressure;a reduced-pressure interface coupled to the sealing subsystem; anda reduced-pressure delivery conduit for providing reduced pressure from the reduced-pressure source to the reduced-pressure interface. 17. The method of claim 12, wherein the closing dressing bolster is formed from a translucent material. 18. The method of claim 12, wherein the closing dressing bolster is formed from a polymer having a stiffness of approximately durometer 50 Shore A. 19. The method of claim 12, wherein the closing dressing bolster is formed from a medical-grade silicone. 20. The method of claim 12, wherein the closing dressing bolster is formed with a gap between the first closing member and the second closing member for receiving a wicking material. 21. The method of claim 12, wherein the closing dressing bolster is formed by one of extrusion, pour molding, injection molding, and blow molding.
