A closing dressing bolster and assembly for use with a system for treating a linear wound on a patient includes a bolster body formed from a flexible closing bolster material having closing members that are operable to develop an inward closing force when the closing dressing bolster is placed under reduced pressure. In one aspect, when the closing dressing bolster is under reduced pressure, the system, dressing, or assembly develops an inward force realized at the linear wound and a compression force. A wicking-material holder and wicking material may be used as well. The member components may all be see-through to allow visual inspection of the wound without requiring removal of the dressing.

According to certain embodiments, an apparatus for applying negative pressure to a wound can include a negative pressure source, a sensor, and a controller. The negative pressure source can be configured to couple via a fluid flow path to a wound dressing and provide negative pressure to the wound dressing. The sensor can be configured to monitor a magnitude or frequency of pressure in the fluid flow path generated by the negative pressure source. The controller can be configured to determine an activity classification, such as breathing, changing positions while lying, sitting, walking, standing, jumping, traversing stairs, leg extending, leg bending, and performing chair squats, based on a change in the magnitude of pressure over time while the negative pressure source maintains the magnitude of pressure in the fluid flow path below a negative pressure threshold. The controller can output an indication of the activity classification.

The present invention relates to a system and method for pulse cycle pressure modulation and negative pressure therapy in a cardio synchronous manner to improve distal limb blood flow applying negative or variable pressure to a portion of the body. The invention relates to methods and apparatus for the application of a sequential and gradient pulse wave for treating wounds that are difficult to heal or livelihood limiting claudication and/or ischemic rest pain. An integral part of the present invention includes methods to determine blood flow and effects of treatments on tissue.

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.

In some embodiments, a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of the wound by preferentially contracting to exert force on the tissue. Some embodiments may utilize a collapsible structure with a plurality of cells.

Disclosed embodiments may relate to dressings configured to provide negative-pressure wound therapy to a tissue site, while simultaneously shielding a portion of the tissue site from the negative pressure. For example, dressing assembly embodiments may comprise an outer dressing configured for applying negative-pressure wound therapy to a tissue site, and an underlying isolation patch configured for use under the outer dressing. The isolation patch may be configured to seal the portion of the tissue site so that it does not experience the negative pressure. Additionally disclosed are other apparatus, dressings, systems, and methods.

Devices and methods for edema management, e.g., reducing edema, are disclosed. A treatment device may include a chamber defining a treatment space, the chamber being fabricated from a substantially impermeable material and configured to conform to the shape of the periphery, an inner surface of the chamber including a plurality of surface patterns, the chamber having a sealing portion at a base; and at least one conduit connected to the chamber and in fluid communication with the treatment space so as to enable the application of a negative pressure to the treatment space. The treatment device may be configured for reducing edema at a target site on a subject. The treatment device may be further configured for edema management, e.g., reducing edema, of at least one breast, e.g., both breasts, of a subject.

Disclosed is a two-way vacuum assisted closure system in the medical field which eliminates leakages based on the upper gastrointestinal system organs such as the stomach and intestine after stab wounds and/or wounds after surgical operations.

In some embodiments, a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of the wound by preferentially contracting to exert force on the tissue. Some embodiments may utilize a collapsible structure with a plurality of cells.

A manifold for use with a dressing for treating an area around an extremity of a patient may include a concave recess positioned at a first end of the manifold. A fold axis may bisect the concave recess and extend from the first end of the manifold to a second end of the manifold. A first portion of the manifold may extend orthogonal to the fold axis toward a first side of the manifold, and a second portion of the manifold may extend orthogonal to the fold axis toward a second side of the manifold opposite to the first side. The fold axis may be configured to extend lengthwise along the extremity. Additionally disclosed are other apparatus, dressings, systems, and methods.
