Membranes, systems, and methods for applying reduced pressure to a subcutaneous tissue site

摘要

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.

主权项

1. A system for applying reduced pressure to a subcutaneous tissue site, the system comprising:
a reduced-pressure source operable to supply reduced pressure; a bioabsorbable membrane consisting essentially of
a single membrane wall having a substantially uniform membrane wall thickness and formed with substantially no perforations;a plurality of projections and a plurality of substantially matched recesses formed by the membrane wall; and a delivery tube coupled to the membrane, the delivery tube operable to deliver the reduced pressure to a tissue-facing surface of the membrane.
