Intended Use

Synthecure Synthetic Calcium Sulfate is an implant intended to fill bony voids or gaps of the skeletal system (i.e. extremities and pelvis). These osseous defects are surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. Synthecure Synthetic Calcium Sulfate resorbs and is replaced with bone during the healing process. Synthecure is provided sterile for single use only. Synthecure is biodegradable and biocompatible and may be used at an infected site.

Device Story

Synthecure Synthetic Calcium Sulfate is a resorbable bone void filler. It consists of calcium sulfate powder and a mixing solution. The clinician mixes these components in a sterile bowl to create a paste. This paste is either packed directly into bone voids or placed into a provided mold to form beads. The device is intended for use in the skeletal system (extremities and pelvis) for defects not requiring structural support. It is biodegradable, radiopaque, and biocompatible, allowing for use at infected sites. The material resorbs in approximately 30-60 days and is replaced by bone during the healing process. It is provided sterile for single-patient use.

Clinical Evidence

No human clinical data provided. Evidence includes bench testing (chemical composition, physical properties, work/setting time, real-time aging) and an animal implantation study in New Zealand White Rabbits with endpoints at 3, 6, and 12 weeks. Biocompatibility evaluated per ISO 10993-1.

Technological Characteristics

Synthetic implant-grade calcium sulfate powder and mixing solution. Forms a paste or beads. Radiopaque, biodegradable, and biocompatible. Sterilization validation to SAL 1x10^-6. Packaging validated per ISO 11607-1:2019 and ISO 11607-2:2019. Bacterial endotoxin testing per ANSI/AAMI ST72:2011.

Indications for Use

Indicated for filling bony voids or gaps in the skeletal system (extremities and pelvis) that are not intrinsic to structural stability, including surgically created defects or traumatic injuries. Suitable for use at infected sites.

Synthecure Synthetic Calcium Sulfate contains calcium sulfate powder and mixing solution in premeasured quantities so that when mixed together in a sterile mixing bowl, the resultant paste is to be digitally packed into open bone void/gap to set in situ or placed into the mold provided where the mixture sets to form beads. The biodegradable, radiopaque beads are resorbed in approximately 30-60 days when used in accordance with the device labeling. Synthecure Synthetic Calcium Sulfate is manufactured from synthetic implant grade calcium sulfate that resorbs and is replaced {6} Synthecure Synthetic Calcium Sulfate with bone during the healing process. Also, as the bone void filler beads are biodegradable and biocompatible, they may be used at an infected site. # INDICATIONS FOR USE Synthecure Synthetic Calcium Sulfate is an implant intended to fill bony voids or gaps of the skeletal system (i.e. extremities and pelvis). These osseous defects are surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. Synthecure Synthetic Calcium Sulfate resorbs and is replaced with bone during the healing process. Synthecure is provided sterile for single use only. Synthecure is biodegradable and biocompatible and may be used at an infected site. # COMPARISON OF TECHNOLOGICAL CHARACTERISTICS Austin Medical Ventures, Inc. believes that the Synthecure Synthetic Calcium Sulfate is substantially equivalent to the predicate devices based on the information summarized here: Synthecure Synthetic Calcium Sulfate is identical in function and intended use to the predicate device. The subject and predicate devices are intended to be implanted into defects not intrinsic to the structural stability of the skeletal system. Additionally, the subject device has a similar design and uses similar materials to the predicate. The subject device and the predicate device are presented as a powder, manufactured from medical grade calcium sulfate, and a mixing solution which, when mixed, form a paste which may be digitally implanted or applied to a mold provided to produce beads. Both are biocompatible and may be implanted at an infected site which resorbs and is replaced by bone during the healing process. These technological characteristics have undergone testing to ensure the device is as safe and effective as the predicates. # SUMMARY OF NON-CLINICAL TESTING Austin Medical Ventures, Inc. has conducted testing per FDA Guidance Class II Special Controls Guidance Document: Resorbable Calcium Salt Bone Void Filler Device (issued on June 2, 2003). The following tests were performed to demonstrate safety based on current industry standards: | Performance Category | Testing | | --- | --- | | Sterilization Validation | Sterilization validation has been completed on the worst-case construct to an SAL of 1x10-6. | | Bacterial Endotoxin Testing | Testing is performed according to ANSI/AAMI ST72:2011, Bacterial endotoxins – Test methods, routine monitoring and alternatives to batch testing. | | Packaging Validation | Packaging performance validation, in accordance with ISO 11607-1:2019 and ISO 11607-2:2019, was performed on the final packaging and sterilized device. | {7} Synthecure Synthetic Calcium Sulfate | Biocompatibility | A biological safety evaluation has been completed for Synthecure according to ISO 10993-1 requirements and FDA Guidance Document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" (issued on September 8, 2023). All materials contained in the proposed Synthecure have been evaluated in accordance with recognized standards and are characterized as being biocompatible. | | --- | --- | | Performance Testing - Bench | The chemical composition and physical properties of the subject and predicate devices were evaluated and demonstrated to be equivalent. Additionally, work and setting time tests were conducted on real-time aged samples to support that the device maintains its performance after aging. | | Performance Testing - Animal | An implantation study was conducted using New Zealand White Rabbits with study endpoints at 3, 6, and 12 weeks. | The results of these tests indicate that the Synthecure Synthetic Calcium Sulfate is substantially equivalent to the predicate devices. # CONCLUSION Based on the testing performed, including sterilization validation, packaging validation, biocompatibility, bench testing and an animal study, it can be concluded that the subject device does not raise new issues of safety or effectiveness compared to the predicate devices. The similar indications for use, technological characteristics, and performance characteristics for the proposed Synthecure Synthetic Calcium Sulfate are assessed to be substantially equivalent to the predicate devices.
