Surgical pin compression wound dressing module, device and system
A surgical pin compression wound dressing stabilizing system includes a compressive wound dressing module having a central orifice and radial slit, and a stabilizing device having a longitudinal passageway and a vertical slit, the slits allowing insertion of the module and stabilizing device on a surgical pin at a wound site with the surgical pin dispose in the orifice and passageway. The stabilizing device has an upright post with the longitudinal passageway and a bottom base with a recessed central cavity open at a bottom that receives and mates with an upper portion of the module. The bottom base has a lower outer annular surface surrounding the central cavity for engaging a peripheral rib on the module to enable application of an equal distribution of a downward compressive pressure on the module.
Methods for manufacturing and assembling dual material tissue interface for negative-pressure therapy
A dressing for treating tissue with negative pressure may be a composite of dressing layers, including a release film, perforated gel layer, a perforated polymer film, a manifold, and an adhesive cover. A method of manufacturing the dressing may comprise providing a first layer, such as the gel layer, on a substrate, perforating the first layer on the substrate to create a plurality of apertures in the first layer, and creating an index of the plurality of apertures in the first layer. A laser can be calibrated based on the index. A second layer, such as the polymer film, may be coupled to the first layer, and a plurality of slots can be cut in the second layer with the laser. Each of the slots can be cut through one of the apertures in the first layer based on the index.
WOUND CLOSURE DEVICE AND METHOD OF USE
A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to exert force on the tissue. Some embodiments may utilize a clamping structure with removable sections.
COLLAPSIBLE STRUCTURE AND METHOD OF USE
A collapsible, clamping and/or steerable apparatus in conjunction with negative pressure system and methods for using such an apparatus are described. Preferred embodiments of the invention have lengths and bent and/or increase their curvatures along their lengths, by preferentially contracting and transforming upon negative pressure.
POST-OPERATIVE SURGICAL WOUND DRESSING
Described herein is a wound dressing comprising: a composite island configured to collectively exhibit substantially elastic recovery under wound treatment conditions and comprising a foam layer and an absorbent layer coupled to the foam layer, the foam layer exhibiting substantially elastic recovery under wound treatment conditions and the absorbent layer not exhibiting substantially elastic recovery under wound treatment conditions; a backing layer having a margin that extends beyond the composite island; and an adherent layer disposed on at least the margin of the backing layer. In addition, described herein is a method of eliminating, minimizing, or reducing edema for a wound surrounded by tissue, by positioning the wound dressing over the wound, optionally such that at least a portion of the adherent layer contacts the tissue.
IN-LINE WOUND FLUID SAMPLING SYSTEMS AND METHODS FOR USE WITH NEGATIVE PRESSURE WOUND THERAPY
Some embodiments provide in-line negative pressure wound therapy (NPWT) sampling assessment systems, comprising: a housing; a wound fluid input port configured to fluidly couple with a first wound fluid lumen extending from a wound treatment site; a wound fluid output port configured to fluidly couple with a NPWT control unit; an in-line sampling chamber positioned within the housing and comprising a theranostic sampling element, wherein the first in-line sampling chamber is configured to: removably and fluidly couple between the input port and the output port in-line with a wound fluid path between the wound treatment site and the NPWT control unit with the first theranostic sampling element positioned so that at least some of the wound fluid contacts at least a portion of the first theranostic sampling element; and decouple out of the wound fluid path without interrupting a negative pressure treatment process applied at the wound treatment site.
PNEUMATIC DEVICE FOR OPENING AND CLOSING A WOUND
A device includes a plurality of pneumatic modules and a pressure control device. The pneumatic modules are configured to attach to a patient's skin along edges of a wound and to translate a pneumatic pressure into a linear force. Each pneumatic module is configured to move between an extended position and a contracted position based on the pneumatic pressure within the pneumatic module. The pressure control device is configured to be pneumatically coupled to each of the pneumatic modules and configured to alternate the pneumatic modules between a first state and a second state. In the first state, the pneumatic pressure within a first set of the pneumatic modules is less than the pneumatic pressure within a second set of the pneumatic modules. In the second state, the pneumatic pressure within the first set of the pneumatic modules is greater than the pneumatic pressure within the second set of the pneumatic modules.
WOUND CARE DEVICES, APPARATUS, AND TREATMENT METHODS
A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply mea, an oxygen consuming mea, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.
Amine-functionalized polymeric compositions for medical devices
The present disclosure provides amine-modified polymer foams, which may be used for wound dressing materials. For example, the modified materials can include a covalently attached molecule comprising free amine groups. Such amine groups can be used, for instance, to conjugate biologically active polypeptides and/or linkers. Methods for using modified polymers are also provided.
Wound pad
Wound pads and systems and kits comprising wound pads whose total thickness can be modified by a user without the use of tools, comprising a plurality of separable layers having layer thicknesses less than the thickness of the wound pad. The wound pads may be used as wound fillers in the context of negative pressure wound therapy (also known as vacuum treatment, reduced pressure treatment).
