The present invention provides a device for wound treatment, comprising a chamber that includes an inner surface and defines a treatment space, the chamber being made of a flexible, impermeable material. The device further includes a plurality of structures configured to exert mechanical stress on a wound, the plurality of structures intruding from the inner surface of the chamber into the treatment space. The device further includes a tube having a first end connected to the chamber, the tube being in fluid communication with the treatment space so as to enable at least one selected from the group of applying negative pressure to the treatment space and applying a therapeutic agent.

A technique and associated instrumentation for correcting large intermetatarsal angles that result from hallux valgus. The system includes a button and a suture loop attached to the button. A suture strand is threaded through holes in the button to attach the button to the suture. The suture ends are then brought together (by being swaged, spliced or cinched together, for example) to form the suture loop comprising a continuous, uninterrupted suture loop with a single strand of swaged-together ends. The swaged-together ends may be attached to a suture passing instrument such as a K-wire (Kirschner wire) that may be further used to drill a hole through the first and second metatarsals. The swaged-together ends of the suture are then passed through the drill holes in the first and second metatarsals; and the ends of the suture are pulled until the button abuts the second metatarsal. The swaged together portion of the suture loop is then cut, and the free suture ends are passed through holes in another (second) button. The suture ends are pulled to adjust the first metatarsal to a correct intermetatarsal angle, and the first metatarsal is secured in place by tying the ends of the suture together against the second button.

Hallux valgus repairs using suture-button construct

A wound dressing includes a chamber () defining a treatment space () and at least one opening () communicating with the treatment space. In one embodiment, a plurality of channels are defined on an inner wall of the chamber. In another embodiment, a tube () extends through the chamber and into the treatment space and defines a plurality of openings () in a portion of the tube extending into the treatment space. In yet another embodiment, a tube extends through the chamber and into the treatment space and comprises a plurality of branches () extending to different regions of the treatment space.

Wound chamber for limb

A portable and disposable device is provided for processing harvested dermal tissue. The device includes a housing presenting a handle having a gripping surface and a cutting head attached to the handle. A cutting assembly is supported by the cutting head and includes a plurality of spaced cutting blades that are rotatable with respect to the housing. A receptacle is disposed downstream of the cutting assembly and receives the sliced tissue from the cutting blades. The device is thus operable to slice harvested tissue into strips, and further into fine particles, that can be used for transplantation onto a wound site.

Method and apparatus for processing dermal tissue

An apparatus is provided to enable the direct gene transfer of genetic material into a target cell site ('microseeding'), as a means of obtaining long term expression of native or non-native polypeptides in a host. The apparatus includes a matrix of microneedles that oscillate at a predetermined frequency and receive the genetic material from a delivery system that is integrated with the apparatus.
