Abstract
The illustrative embodiments described herein are directed to apparatuses, systems, and methods for applying reduced pressure to a subcutaneous tissue site. In one illustrative embodiment, the apparatus includes a membrane having a substantially uniform membrane wall thickness and a first, tissue-facing surface. The membrane may be shaped to form a plurality of protrusions on the tissue-facing surface. The plurality of protrusions at least partially defines at least one channel operable to transfer the reduced pressure along the tissue-facing surface.
Claims25
A system for applying reduced pressure to a tissue site, the system comprising:
- a reduced-pressure source operable to supply reduced pressure;
- a membrane having a plurality of projections on a first, tissue-facing surface and a plurality of substantially matched recesses on a second surface of the membrane, the plurality of projections at least partially defining at least one channel operable to transfer the reduced pressure along the tissue-facing surface;
- and
- a delivery tube coupled to the membrane, the delivery tube operable to deliver the reduced pressure to the tissue-facing surface of the membrane.
A system for applying reduced pressure to a tissue site, the system comprising:
- a reduced-pressure source operable to supply reduced pressure;
- a membrane having a plurality of non-planar, matched deviations on opposite sides of the membrane, the membrane having at least one channel operable to transfer the reduced pressure along a first, tissue-facing side of the membrane;
- and
- a delivery tube coupled to the membrane, the delivery tube operable to deliver the reduced pressure to the tissue-facing surface of the membrane.
A system for applying reduced pressure to a subcutaneous tissue site, the system comprising:
- a reduced-pressure source operable to supply reduced pressure;
- a membrane having a substantially uniform membrane wall thickness and a first, tissue-facing surface, the membrane being shaped to form a plurality of protrusions on the tissue-facing surface, the plurality of protrusions at least partially defining at least one channel operable to transfer the reduced pressure along the tissue-facing surface;
- and
- a delivery tube coupled to the membrane, the delivery tube operable to deliver the reduced pressure to the tissue-facing surface of the membrane.
