Examples of a negative pressure wound closure system and methods for using such a system are presented. Certain embodiments facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Certain embodiments can utilize tissue securing portions that aid in securing the system within a wound.

Negative pressure wound closure device

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 securing portions that aid in securing the invention within a wound.

Systems, devices, and methods of the present application relate to the diagnostic measurement of condition for pressure ulcers. Preferred embodiments utilize pressure measurements at body locations to determine a diagnostic pressure ulcer value. A pressure sensor device generates patient pressure data that is processed by a data processor which utilizes a diagnostic function to determine the diagnostic value that indicates whether corrective action is needed to prevent pressure ulcer formation. One or more sensor devices can be attached to a patient to measure to transmit data for further processing.

Systems and methods for prevention of pressure ulcers

A negative pressure wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize a stabilizing structure with a plurality of cells configured to collapses more in the x-direction than in the y-direction.

Wound closure devices

A surgical elevator device that can be used in the reduction of bone fractures, particularly facial bone fractures, and even more particularly zygomatic arch fractures. The elevator device enables accurate measurement of the depth of insertion of the device into tissue space and provides tactile control of fracture location and reduction. In one embodiment, the elevator device comprises a groove on an elevator element for receiving a bone structure. The groove can be formed by a pair of parallel ridges. A projection extending from the elevator provides a pivot point for applying a controlled force to the bone to reduce the fracture. A preferred embodiment further comprises a method of reducing a bone fracture, such as a zygomatic arch fracture.

Zygomatic elevator device and methods

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, devices, and methods of the present application can accelerate and reduce medical complications associated with healing of non-planar wounds such as amputation wounds. The devices and methods utilize a collapsing structure and negative pressure to cause the shaped wound to preferentially close. The structure can accommodate movement over curved tissue surfaces, which can utilize scales or interleaved elements to provide efficient wound closure along arcuate paths. This structure can enable gradual closure from the deepest portion of the wound to the shallowest portion.

The present invention relates to wound closure devices, systems and methods. Embodiments of the invention facilitate closure of the wound by preferentially contracting under negative pressure to provide for movement of the surrounding tissues. Some embodiments may utilize tissue securing portions that aid in securing the invention within a wound.

Certain embodiments described herein are directed to an elongated layer of material and a lip to be placed in contact with a wound and the elongated layer of material to be wrapped around a wound filler, their methods of use and systems incorporating the same, wherein the wound filler lip is configured to be positioned beneath the fascia. Additionally, some embodiments described herein are directed to the closure of the wound and the use of attachment mechanisms on the elongate layer and lip to attach to the wound surface.

Negative pressure wound closure device and systems and methods of use in treating wounds with negative pressure

The present invention relates to devices and methods for measuring vascular deficiency using Doppler ultrasound detection. Embodiments can be used to monitor the condition of surgical tissue flaps or other conditions in which obstruction in the vascular system can impact patient health. The systems can include a Doppler ultrasound probe, a color probe, a temperature probe, and/or other suitable probes to measure blood volume and perfusion status of a tissue region. The systems and methods can be used to monitor flaps after flap transplant surgeries. The systems and methods can automatedly assess tissue condition and alert the patient or medical staff if the condition has fallen below a threshold indicating occlusion of a blood vessel. One or more additional sensors can be integrated into a probe to measure vascular conditions and a metric can be computed based on sensed data.

Devices and methods for treating and closing wounds with negative pressure

A surgical drain device includes an adhesion matrix of biodegradable polymer material and a plurality of drain tubes attached to the matrix. The device is implanted within a surgical wound to treat the presence of seromas, for example, and is used to promote drainage, tissue adhesion, and wound closure. The drain tubes converge into a common collection tube that leads wound fluid outside the body under gravity feed or negative pressure applied to the collection tube. The matrix contains an array of apertures that allow tissue contact across the device. The device also can include a coating of surgical adhesive and a tissue anchoring system of hooks or barbs. The device can be used with a negative pressure system to further improve the drainage band can also be used with a wound dressing. The device and systems containing the device are particularly useful to promote the healing of surgical wounds from abdominal surgery.
