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 comprising: a conduit holder having a first bulkhead surface, a second bulkhead surface, a top surface being convex in shape, and a bottom surface conformable in shape to a tissue contact region proximate to a tissue site;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 a source of reduced pressure;a flexible membrane connected to the bottom surface of the conduit holder and extending beyond the first bulkhead surface to form a bridge overlay zone adjacent the first bulkhead surface; anda porous pad having a primary delivery region configurable to contact the tissue site and a porous bridge configurable to contact the first bulkhead surface in fluid communication with the first conduit and the bridge overlay zone. 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 access 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 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 conduit holder further comprises: a first flexible membrane forming the bottom surface;a second flexible membrane forming the top surface; anda moldable material disposed between the first and second flexible membranes to encase the first conduit between the first and second flexible membranes. 16. The apparatus of claim 15, wherein the first and second membranes are nitrile film. 17. The apparatus of claim 1, further comprising a porous extension region configurable to extend perpendicularly from the primary delivery region into the tissue site. 18. The apparatus of claim 17, wherein the porous tension region and the primary delivery region include a plurality of flow channels to facilitate distribution of reduced pressure and fluids from the tissue site. 19. The apparatus of claim 17, wherein the porous extension region and the primary delivery region are a single component. 20. The apparatus of claim 1, wherein the porous bridge region has a side surface contacting the first bulkhead surface and having a cross-sectional shape similar to the first bulkhead surface. 21. 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. 22. The apparatus of claim 1, wherein the porous bridge region has a side surface contacting the first bulkhead surface and being substantially perpendicular to the tissue site. 23. The apparatus of claim 1, wherein the primary delivery region and the porous bridge region are separate components, each having a contact surface in fluid communication with the contact surface of the other. 24. The apparatus of claim 1, wherein the primary delivery region and the porous bridge region are discrete components. 25. The apparatus of claim 1, wherein the porous pad comprises open-cell foam. 26. The apparatus of claim 25, wherein the porous pad is polyurethane. 27. The apparatus of claim 25, wherein the open cells of the porous pad are interconnected to act as flow channels to facilitate the distribution of reduced pressure from the tissue site.
