The present technology generally relates to an absorbent biophotonic fiber system and to articles comprising the absorbent biophotonic fiber system as well as to the potential uses thereof, such as, for example, in wound treatment.

A surgical sponge including a sponge material configured an elongate sponge having multiple compressed layers and a flattened shape characterized by a generally flat upper surface, a generally flat lower surface, with the sponge having a thickness that is substantially less than a width of the sponge, one reduced dimension end of the elongate sponge having an end length and reducing in dimension distally along the end length; stitches along the length of the sponge to compress the sponge material and maintain the layers in compression to maintain the flattened shape of the sponge; and a length of stitch material extending from the reduced dimension end to provide a structure that is engageable for use in positioning or removal of the sponge during a surgical procedure.

Negative pressure wound therapy sponges that are custom-fabricated to fit a given wound to be treated, corresponding methods of creating said sponges in situ or external to a wound, and related systems for performing negative pressure wound therapy using said sponges. Exemplary sponge embodiments may have pressure-sensing capabilities.

A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.

Described herein are tissue grafts derived from the placental tissue that are reinforced with at least one biocompatible mesh. The tissue grafts possess good adhesion to biological tissues and are useful in wound healing applications. Also described herein are methods for making and using the tissue grafts.

The present invention relates to a composition that can be used as or as part of a wound dressing and to wound dressings comprising the same. More specifically, the present invention relates to a composition that disrupts and kills bacteria within a biofilm and also prevents biofilm formation. The composition comprises a first component selected from the group consisting of chitosan, chitin, derivatives of chitosan, derivatives of chitin, and combinations thereof; at least one triprotic acid and at least one solubilising acid.

A foam laminate dressing includes a first distinct hydrophobic reticulated foam layer and an underlying second distinct hydrophilic layer bonded to the first layer and of substantially same length and width as the first distinct hydrophobic reticulated foam layer.

A composite material (and its manufacture) is described that has (i) a first layer comprising an absorbent fiber material that is in contact with the area of use on its first side, (ii) a second layer comprising an absorbent material, said second layer being arranged on the second side of said first layer, wherein a plurality of channels extends through the entire first layer, from said first side to said second side thereof, and further extends into at least a portion of said second layer. This composite is of particular use in wound treatment.

Snap band dressing devices and methods are disclosed. The snap band dressing device serves to protect a point of entry from bacteria and other elements found outside the body. For example, the snap band in dressing devices may include a snap band having an elongated open shape and a coiled closed shape, and a layer integral with or coupled to the snap band and configured to elute a fluid to a wound site when the snap band is positioned around the circumferential wound site in the coiled closed shape. Methods are also provided including snapping a snap band in a coiled closed shape about a circumferential wound site and eluting an antimicrobial substance to a wound site when the snap band is positioned around the circumferential wound site in the coiled closed shape.

Suture delivered patches adapted for interposition, augmentation or repair devices for use in tendon and ligament repair, including rotator cuff repair, have been developed as well as methods for their delivery using suture guided arthroscopic methods. The repair patches may be provided from suitable biocompatible materials. The patches may be delivered using anchored sutures already in use during a surgical repair including, open, minimally invasive, endoscopic, and arthroscopic repair procedures. Additionally, fixation of the suture delivered repair patch is secured along with the normal suture securing workflow of the one or more sutures used to deliver the patch.
