Abstract: 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.

Abstract: A surgical drain device includes a 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. A preferred embodiment comprises a tissue anchoring system including anchor elements such as 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.

Abstract: Contoured surgical instruments, including contoured forceps gripping surfaces, are presented. The instruments can have a first arm with a contoured surface and a second arm with a contoured surface to provide for rotation in the hand of a user. Instruments including the contoured gripping surfaces have an ergonomic shape, favorable weight distribution, improved tactile response, and a construction suitable for precise grasping and manipulation required in many surgical procedures. The contoured gripping surfaces are applicable to a variety of dental and surgical instruments.
