Wound dressing and method of use
A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.
Re-epithelialization wound dressings and systems
Methods, apparatuses, and systems for promoting re-epithelialization as an aspect of wound healing are presented. A re-epithelialization dressing for use with reduced pressure has a moist tissue-interface layer, a manifold member, and a sealing member. The moist tissue-interface layer has a plurality of apertures. The moist tissue-interface layer is for disposing adjacent to the wound and provides a moisture balance (i.e., provides moisture when the wound is dry and receives moisture when the wound site is substantially wet). The reduced pressure, apertures, and moist tissue-interface layer help with liquid management and otherwise promote re-epithelialization. Other systems, apparatuses, and methods are presented.
Reduced-pressure, tunnel-wound dressings, systems, and methods
Systems, methods, and dressing are presented for treating a tunnel wound on a patient. In one instance, a reduced-pressure, tunnel-wound dressing includes a longitudinal core member formed from a closed-cell foam that is surrounded by a first longitudinal concentric member formed from a manifolding material. When subjected to reduced pressure, the longitudinal core member expands and the first longitudinal concentric member compresses. These actions create intimate contact between the tunnel wound and the dressing, oppose collapse of the tunnel, and when reduced pressure is removed provide clearance to remove the dressing. Other embodiments are presented.
Wound dressing and method of use
A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.
Reduced-pressure, compression systems and apparatuses for use on a curved body part
A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.
DEVICES, SYSTEMS, AND METHODS FOR INSTILLATION OF FOAMED FLUID WITH NEGATIVE PRESSURE WOUND THERAPY
Systems and methods for delivering a foamed fluid to a wound of a patient (e.g., through a wound dressing covering the wound and coupled to the skin around the wound).
Surgical cavity drainage and closure system
A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device can be used with a negative pressure system to further improve the drainage band can also be used with a wound dressing. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.
Wound treatment apparatus and method
An apparatus and method for aspirating, irrigating and/or cleansing wounds is provided. The apparatus and method include one or more of the following: simultaneous aspiration and irrigation of the wound, supplying of thermal energy to fluid circulated through the wound; supplying physiologically active agents to the wound; a biodegradable scaffold in contact with the wound bed; and application of stress or flow stress to the wound bed.
Granulating Chronic Wound Dressing
In some non-limiting examples, a system for stimulating tissue growth at a tissue site may include an interactive body including a body mass and a tissue contact surface configured to contact the tissue site. A plurality of struts and a plurality of voids may be exposed at the tissue contact surface, and may define a tissue interface pattern at the tissue contact surface. The tissue interface pattern may be configured to engage the tissue site and to create tissue deformation in combination with the body mass. Also provided are other systems, apparatus, and methods suitable for stimulating tissue growth.
PRESSURE APPARATUS TO REDUCE SWELLING AFTER MEDICAL DEVICE IMPLANTATION AND RELATED METHOD
A pressure system and method for managing post-operative swelling. The pressure system has a balloon with a quadrilateral basal skirt that surrounds a surgical site on a patient. A plurality of strap-receiving slots is located in the skirt. Adhesive pads are affixed to the patient outside the skirt. One or more tensioning straps are deployed between the strap-receiving slots and the adhesive pads so that tension can be applied to the straps and to the skirt in order to press the balloon upon the surgical site. Optionally, means for generating visual feedback cues are provided to enable the operator to determine appropriate compression and assess skin recoil feedback. Such means may signify swelling reduction and skin turgor.
