A low-profile reduced pressure treatment apparatus and system are provided. The apparatus includes a moldable conduit holder, a conduit through the conduit holder, and a flexible base. The conduit holder has first and second bulkhead surfaces, a convex top surface, and a bottom surface adapted to conform to a tissue contact region adjacent to a tissue site. An end of the conduit is substantially flush with the first bulkhead surface and a longitudinal axis of the conduit is substantially perpendicular to the first and second bulkhead surfaces. The base is connected on a first side to the bottom surface of the conduit holder, and extends beyond the first bulkhead surface to form an overlay zone adjacent the first bulkhead surface. An adhesive is disposed on a second side of the flexible base to secure the flexible base to the tissue contact region.

1. A reduced pressure treatment apparatus for use with a porous pad having a first portion configurable to contact a tissue site and a second portion configurable to receive reduced pressure, comprising: a conduit holder having a first bulkhead surface configured to contact the second portion of the porous pad, a second bulkhead surface configured to be coupled to a source of reduced pressure, a bottom surface conformable in shape to a tissue contact region proximate to the tissue site, and a top surface having a convex shape;a first conduit extending through the conduit holder from the first bulkhead surface to the second bulkhead surface and adapted to receive reduced pressure from the source of reduced pressure through the second bulkhead surface and to be in fluid communication with the second portion of the porous pad through the first bulkhead surface; anda flexible membrane connected to the bottom surface of the conduit holder and extending beyond the first bulkhead surface to form a bridge overlay zone adapted to be in fluid communication with the second portion of the porous pad. 2. The apparatus of claim 1, further comprising a second conduit having a first end in fluid communication with the first conduit at the second bulkhead surface and adapted for receiving reduced pressure from the source of reduced pressure. 3. The apparatus of claim 2, wherein the first end of the second conduit extends into the first conduit. 4. The apparatus of claim 3, wherein the first end of the second conduit is flush with the first of bulkhead surface. 5. The apparatus of claim 2, wherein the second conduit has a longitudinal axis perpendicular to the second bulkhead surface. 6. The apparatus of claim 2, further comprising a drape configurable to cover and create a sealed space around the first conduit, the first end of the second conduit, the conduit holder, and the porous pad, wherein the first conduit is generally parallel to the tissue contact region. 7. The apparatus of claim 1, wherein the conduit holder is formed from room-temperature-vulcanizing silicone. 8. The apparatus of claim 1, wherein the flexible membrane is a polyurethane material. 9. The apparatus of claim 1, wherein the flexible membrane is adhesively connected to the bottom surface of the conduit holder. 10. The apparatus of claim 1, further comprising a drape having a first side adhesively connected to the flexible membrane. 11. The apparatus of claim 10, wherein the drape has a second side having an adhesive surface adapted to be applied to the tissue contact region. 12. The apparatus of claim 11, wherein the adhesive surface is biocompatible. 13. The apparatus of claim 12, wherein the adhesive surface is an acrylic material. 14. The apparatus of claim 11, further comprising a protective liner covering the adhesive surface. 15. The apparatus of claim 1, wherein the second portion of the porous pad has a side surface contacting the first bulkhead surface. 16. The apparatus of claim 15, wherein the side surface has a similar cross-sectional shape as the first bulkhead surface. 17. The apparatus of claim 1, wherein the porous pad has a thickness (t) and the conduit holder has a height (h) that are substantially equal. 18. The apparatus of claim 1, wherein the porous pad has a porous bridge region having a side surface contacting the first bulkhead surface substantially perpendicular to the tissue site. 19. The apparatus of claim 1, wherein the first portion and second portion of the porous pad are separate components. 20. The apparatus of claim 19, wherein each of the first portion and the second portion of the porous pad have a contact surface in fluid communication with the other contact surface. 21. The apparatus of claim 1, wherein the first portion and second portion of the porous pad are a single unit forming the porous pad. 22. The apparatus of claim 1, wherein the porous pad comprises an open-cell foam. 23. The apparatus of claim 22, wherein the porous pad is polyurethane. 24. The apparatus of claim 22, wherein the porous pad has open cells interconnected as flow channels to facilitate the distribution of reduced pressure from the tissue site.
