The canister may be combined with the dressing.

Wound irrigation system
11504457 · 2022-11-22 · ·

A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

Collapsible structure for wound closure and method of use

In some embodiments, a negative pressure wound closure system and methods for using such a system are described.

Some embodiments may utilize a collapsible structure with a plurality of cells.

Medical treatment systems and related methods thereof

A medical system including a compressible device, and a covering over the compressible device, wherein the covering includes a delivery configuration and a deployed configuration, wherein, in the delivery configuration, the covering at least partially covers the compressible device to maintain the compressible device in a compressed state, and wherein, in the deployed configuration, the covering is releasable from the device to transition the compressible device from the compressed state to an expanded state.

Negative pressure wound treatment apparatuses and methods with integrated electronics

Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound contact layer, an absorbent layer over the wound contact layer, the absorbent layer comprising one or more apertures, a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer, and an electronics assembly comprising a negative pressure source. The cover layer can be configured to be compressed within the aperture in the absorbent layer when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer. In some embodiments, the wound dressing apparatus can comprise an indicator material layer configured to protrude when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer.
