A negative pressure therapy unit is disclosed that is designed for healing internal wounds under the application of negative pressure. A plurality of tubes sequentially movable relative to one another are used to locate a filler material inside the organ. The tubes cover the filler material to avoid contact with the organ and filler material. A pressure tube passes internally to the plurality of tubes and communicates with the filler material. The filler material is in a compressed state between at least one of the plurality of tubes and the pressure tube. Translation of one of the plurality of tubes selectively exposes the filler material and permits the filler material to expand into the wound. The filler material is interchangeable on the wound and selectively on the pressure tube.

A device and method for treatment of post-operative surgical site wounds. Device includes an elongated hollow shaft that spans from the wound closure to the deep wound area, the internal end abutting a wound dressing and the external end connecting to a device that can provide negative-pressure suction and irrigation. Device providing one or more of irrigation, suction, and/or local antibiotic delivery to deep infections through a closed-wound. The method for removal includes narrowing a removal element relative to the long axis, collapsing the wound dressing; removing the wound dressing through the elongated shaft; and removing the device through a closed wound, avoiding a second removal surgery.

System for percutaneous drainage of a drainage site includes a catheter, a drain tube, a first pump, a flush tube, a second pump, and a controller. The catheter includes a drain lumen defined by a first portion of a catheter wall and a septum, and a flush lumen defined by a second portion of the catheter wall and the septum. The flush lumen is separated from the drain lumen by the septum. The septum has at least one septal hole disposed therein such that the drain lumen and the flush lumen are in communication via the at least one septal hole. The catheter wall has at least one wall hole disposed therein such that the drain lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site.

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.

Example apparatuses and systems are disclosed for providing controlled delivery of electrolysis products to a site which may be used for treatment of infection and ablation of undesirable cells and tissue. A system disclosed may include a power supply, two electrodes, an aqueous matrix that may close the electric circuit between the electrodes at the treated site, and a controller. The controller may control the electrical circuit to induce a direct current through the electrodes and an aqueous matrix to produce electrolysis products. The duration and magnitude of the charge applied may determine the dose of the products applied to the treatment site. The composition of the electrodes and the aqueous matrix may be chosen to produce desired products. An apparatus is disclosed that may be in the form of a pad for applying to a wound. An apparatus is disclosed that may be used for treating internal tissue.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

Systems, methods, and apparatuses for regulating the delivery of negative-pressure therapy are described. The system includes a negative-pressure source, an energy source, and a switch. The switch can include a first conductor electrically coupled to the negative-pressure source, a second conductor electrically coupled to the energy source, and a diaphragm having a first position electrically coupling the first conductor to the second conductor and a second position separated from the first conductor and the second conductor. The diaphragm is configured to move between the first position and the second position in response to a differential between a control pressure and a therapy pressure.

Disclosed herein are several embodiments of a wound treatment apparatus employing a fluidic connector for negative pressure wound therapy and methods of using the same. Some embodiments are directed to improved fluidic connectors for connecting to a wound site, for example a fluidic connector including a reinforcement, and methods of using the same.

A wound packing material, particularly suitable for use in negative pressure wound therapy, comprising a porous material admixed with a chemoattractant. This disclosure further provides methods of manufacturing the wound packing material, and therapeutic methods of using the wound packing material.
