A housing of a pump unit is fixed to a drape of a wound dressing by a joint portion. A suction chamber that is brought into a negative pressure by driving of a piezoelectric pump directly communicates with a closed space through an opening and an inlet. Hence, a therapy device does not need to include a pipe that allows the closed space and the pump unit to communicate with each other. Therefore, since the therapy device does not need to include the pipe that allows the pump unit to communicate with the closed space, detachment of the pump unit from the wound dressing owing to coming-off of the pipe is avoided. Since the housing is fixed to the drape by the joint portion, the pump unit can be prevented from detaching from the wound dressing.

The disclosed technology relates to a wound dressing comprising a vertically lapped material. The disclosed technology further relates to methods and uses of the wound dressing.

Provided herein are methods for making foam materials and foam material products having a polyurethane foam matrix defining a plurality of pores, a hydrophilic agent retained within at least a portion of the pores for improving an absorption of the foam material, a salt retained within at least a portion of the pores in an amount sufficient to render the foam material isotonic, a surfactant retained within at least a portion of the pores in an amount sufficient to be released upon contact with a moist surface. Also provided herein are methods for making a multilayer foam by casting a second foam layer on a first foam layer substrate and compressing the second foam layer before the second layer is fully cured to form an interface layer in situ.

A wound dressing comprising a component wherein said component comprises a planar backing sheet and a yarn wherein the yarn extends through the planar backing sheet from the first side of the sheet to form a plurality of tufts on the second side of the planar backing sheet. Also disclosed is a component comprising an elastomeric planar backing sheet and an absorbent yarn and a component comprising a planar backing sheet and a monofilament yarn wherein in each case the yarn extends through the planar backing sheet from the first side of the sheet to form a plurality of tufts on the second side of the planar backing sheet. Also disclosed is a method of manufacturing the components, a wound dressing or a negative pressure apparatus comprising the components and a method of treating a wound using said wound dressing or negative pressure apparatus comprising the components.

A dressing includes a first felted foam layer, a superabsorbent material printed on the first felted foam layer, and a second felted foam layer coupled to the first felted foam layer. The superabsorbent material is confined between the first felted foam layer and the second felted foam layer.

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.

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.

The invention relates to a multi-layer wound dressing for applying negative pressure to a wound. The dressing comprises a bioresorbable layer, for placement in contact with the wound; a fluid impermeable occlusive outer layer; a fluid porous porting layer positioned between the outer layer and the bioresorbable layer; and a fluid conduit in fluid communication with the porting layer, for coupling to a source of negative pressure. The porting layer comprises a multiplicity of fluid pathways between the conduit and the bioresorbable layer to allow for fluid transfer through the layers of the dressing to and from the bioresorbable. The bioresorbable layer comprises a plurality of apertures to enable exudate to flow from the wound to the porting layer.

Disclosed herein are improved methods and apparatuses for providing hemostasis within a cavity defined by an internal surface of a bleeding tissue space. A catheter comprising a proximal end and a distal end may be advanced into the cavity through a proximal opening of the tissue space into the cavity. A distal balloon coupled to the catheter may be positioned adjacent a distal opening of the tissue space, and expanded to seal the distal opening. A hemostatic agent may be applied from the catheter to the internal surface of the tissue space to inhibit bleeding of the tissue space. The hemostatic agent may be applied without occluding the proximal opening, the distal opening, and a path extending therebetween with the hemostatic agent.

The invention relates to a wound cleansing device comprising a number of strand-shaped cleansing elements, characterized in that the cleansing quotient R=(E*F)/l of at least some cleansing elements is 0.05 N/mm or larger, particularly 0.1 N/mm or larger, preferably 1 N/mm or larger, particularly preferably 10 N/mm or larger and smaller than 1000 N/mm, preferably less than 500 N/mm, in particular 100 N/mm or smaller, wherein E denotes the modulus of elasticity of the material of which the cleansing elements are made, F denotes the average cross-sectional area of the cleansing elements in a direction perpendicular to the strand axis, and l denotes the effective length of the cleansing elements.
