Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

Abstract: A customizable wound treatment system for treating multiple zones of a wound includes a dressing configured for use with a first zone and a second zone of a wound that includes a first foam layer placed over the first zone, a second foam layer placed over the second zone, a first drape layer disposed over the first foam layer and beneath the second foam layer, and a second drape layer disposed over the second foam layer. The customizable wound treatment system includes a negative pressure source pneumatically coupled to the first foam layer and the second foam layer and operable to create a negative pressure at the first zone and the second zone and a fluid instillation pump fluidly coupled to the first foam layer and configured to instill a treatment fluid to the first zone.
