#### Device Description 3.

Panther StereoSeed is an optional software module that has been added to the existing Prowess Panther Brachy system to produce a seed implant plan that is optimized for seed locations and needle directions. The key distinction between Panther StereoSeed and traditional brachytherapy systems is that StereoSeed allows plans to be created such that bones and critical structures can be avoided.

#### 4. Intended Use

Panther StereoSeed is intended to create a plan that is optimized for seed locations and needle directions, allowing needles to be inserted in any angle in order to avoid bones and critical structures.

{4}------------------------------------------------

#### 5. Summary of Comparisons to Predicate Devices

Panther StereoSeed is substantially equivalent to predicate devices, MIM 5.2 (Brachy) by MIM Software Inc. and VariSeed 7.0 by Varian Medical Systems, Inc. for the purposes of premarket clearance, as demonstrated and documented in this premarket notification submission. In addition, the rationalization for substantial equivalence is further evidenced through discussion of similar technological characteristics between StereoSeed and the predicates, as well as test results, which prove that Panther StereoSeed is as safe and effective as the predicate devices.

#### 6. Summary of Technological Considerations

Panther StereoSeed has many of the same technological characteristics as the predicate devices. There is a limited amount of distinguishing factors when comparing StereoSeed to the predicates, and those features that are different do not affect safety or effectiveness. This is described in detail in Section VIII: Substantial Equivalence Comparison.

#### Summary of Non-clinical Tests 7.

A hazard analysis was conducted, and associated documentation is included in Section XI. Methods for preventing and/or mitigating defined hazards are detailed in Section X: Software Verification & Validation. Verification and validation of the software was performed in-house according to established test plans and protocol, which have been included in Section IX as well. Functional testing was conducted both in-house and at the Department of Minimal Invasive Cancer Center of Inner Magnolia Cancer Hospital (IMCH) in Hohhot City, China. In addition, relevant regression testing was conducted by Prowess Quality Assurance to ensure that changes to the software did not result in any unanticipated, negative impact on other areas of the software. Verification and validation testing has demonstrated that Panther StereoSeed has met its predetermined specifications, demonstrated substantially equivalent performance to the predicate device, functions as intended, and is safe and effective for its specified use.

#### Summary of User Site Testing 8.

Although clinical testing is not required to demonstrate substantial equivalence in safety and effectiveness, we elected to conduct beta testing at the Department of Minimal Invasive Cancer Center of Inner Magnolia Cancer Hospital (IMCH) in Hohhot City, China using real patient cases, in order to obtain feedback and to verify the results of in-house testing in a user environment. We feel that no matter how carefully a product is tested at the manufacturer's facility, such testing cannot replace actual use of the device in a clinical setting. As such, we consider both in-house testing at a user site during device development to verify safety and effectiveness, as well as to ensure that benefits to the patient from treatment with the device outweigh any inherent risks.

#### 9. Labeling

The CD media labeling, Instructions for Use, Panther Brachy User Manual, and marketing material are provided in Section IX of this submission. The User Manual, in digital format, is also included in the software media and can be viewed as part of the on-line help.

{5}------------------------------------------------

Product labels comply with 21 CFR 1040.10 and 1040.11 as applicable. In addition, labeling complies with applicable requirements of 21 CFR 801, including the requirement that the device be provided with adequate directions for use.

#### Summary of Safety and Effectiveness Information 10.

- Prowess, Inc. is a registered medical device establishment, whose quality system meets the a. requirements of ISO 13485, Annex II of Medical Device Directive 93/42/EEC, and FDA's QSR, 21 CFR 820.
- b. Panther StereoSeed was designed and implemented according to established Prowess Inc. established design and development, as well as quality management, procedures of Prowess Inc. In addition, design and development of the medical device software complies with internationally recognized standards including ISO 14971:2007 Medical devices – Application of risk management to medical devices, IEC 62304 Medical device software – Software life cycle processes, and IEC 62083 Medical electrical equipment – Requirements for the safety of radiotherapy treatment planning systems.
- The management of the company is committed to the highest standards of quality ﻥ management. The Quality Management System is subject to regular, planned and documented audits by external consultants and by the FDA.
- d. A comprehensive risk analysis has been conducted. Detailed methods of mitigating these potential risks have been identified by the development team, and verified by clinical physicists contracted by Prowess and determined to be adequate.
- e. The software has been verified and validated based on established testing plans. The functionalities have been tested by in-house test engineers. In addition to in-house testing, the system was also tested by our beta-site using clinical cases. Documentation of these tests is included in Section X of the submission.
- f. Directions and precautions for safe and effective use are included in the Instructions for Use and User Manual. Training by a Prowess specialist is also provided as part of product distribution/installation.

#### Level of Concern 11.

As medical device software, the submission for Panther StereoSeed follows FDA's Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices. Since prior to mitigation of hazards, a failure of the software device could results in death or serious injury to a patient, it has been determined that the software correlates to a Major Level of Concern, and as such, the associated documentation is included in this submission.

#### 12. Conclusions

Panther StereoSeed is substantially equivalent to the predicate devices for the purposes of FDA clearance for commercial distribution. It has the same intended use and similar technical characteristics. The software has been found to perform as intended and the benefits to patient and user outweigh any inherent risks, which has been demonstrated via in-house testing as well as in field tests. Its use does not raise any new safety or effectiveness concerns when compared to the predicates.
