The WASTON General Spinal System is intended for posterior pedicle screw fixation of the non-cervical posterior spine in skeletally mature patients. It provides stabilization of spinal segments as an adjunct to fusion in the treatment of the following acute and chronic instabilities deformities: (1) trauma (i.e. fracture or dislocation), (2) curvatures (scoliosis, kyphosis, and/or lordosis), (3) spinal tumor, (4) failed previous fusion, (5) spinal stenosis. It is not intended for pedicle screw fixation above T8.

The WASTON General Spinal System consists of Fixed-Angle Screws, Fixed-Angle Reduction Screws, Rods, Crosslink and Set Screws. The proposed general spinal system is made of Titanium Alloy (Ti6Al4VELI), which meets ASTM F136-02a, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications, which are widely used for surgical implants with well-known biocompatibility. The proposed devices are provided non-sterile. It is required to be sterilized via autoclave method to reach a SAL of 10th by the hospital prior to surgery. The recommended sterilization method was validated per ISO 17665-1: 2006 Sterilization of health care products -- Moist heat -- Part 1: Requirements for the development, validation, and routine control of a sterilization process for medical devices.

WASTON Metallic Bone Plate and Screw Systems are intended for buttressing multifragmentary distal femur fractures including: supracondylar, intra-articular condylar, periprosthetic fractures and fractures in normal or osteopenic bone, nonunions and malunions, and osteotomies of the femuri

The proposed products, WASTON Metallic Bone Plate and Screw Systems, contain (1) Distal lateral femoral (condylar) LOC plate, (2) Bone screws and (3) various specific instruments. The raw material of the plate, titanium, conforms to ASTM F67-13, Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNS R50400, UNSR50550, UNS R50700). The bone screws are made of titanium alloy (TI-6AL-4V ELI), which complies with ASTM F136-13, Standard Specification for Wrought Titanium-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401). The devices are provided un-sterilized, but shall be sterilized via autoclave method to achieve Sterility Assurance Level of 10-6 by hospital prior to use.

The Disposable Circular Stapler is intended to be used throughout the alimentary tract for the creation of end-to-end and end-to-side anastomosis.

The Disposable Circular Stapler places a circular, double staggered row of titanium staples and resects the excess tissue, creating a circular anastomosis. The instrument is activated by squeezing the handle firmly as far as it will go. It is applicable to end-to-end and end-to-side anastomosis. The proposed device is provided EO sterilized.
