## INDICATIONS FOR USE

The Pre-Formed Penile Silicone Block is intended for use in augmentation, reconstructive and cosmetic surgery, and is contoured at the surgeon's discretion to create a custom implant. When used in augmentation procedures, the device provides cosmetic augmentation of the penis and is intended for aesthetic purposes.

## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

The subject device has identical dimensions, design, materials, and technological characteristics as the predicate device (K181387). The subject and predicate devices have the same intended use, as both are intended to be implanted in the penis as a space-occupying substance in cosmetic surgeries.

## SUMMARY OF NON-CLINICAL TESTING

Because no changes in technological characteristics are made for the subject device compared to the predicate device, non-clinical testing, such as biocompatibility, sterilization, and non-clinical performance testing is not needed to support a substantial equivalence of the subject device to the predicate.

## SUMMARY OF CLINICAL TESTING

The Pre-Formed Penile Silicone Block is intended for use in visual augmentation, reconstructive and cosmetic surgery, and is contoured at the surgeon's discretion to create a custom implant. In a retrospective study, 526 patients underwent elective cosmetic penile surgery using the Pre-Formed Penile Silicone Block over a period of five years. Approval from the Institutional Review Board was obtained to perform a retrospective analysis of the cosmetic surgery outcomes. Of the 526 patients who underwent elective cosmetic penile surgery using the subject device, 400 patients responded to the study author's request for consent and were included in the study. The outcomes of their surgeries are summarized here. Clinical effectiveness of the subject device was evaluated via changes in penile measurements, changes in the Augmentation Phalloplasty Patient Selection and Satisfaction Inventory (APPSSI), changes in patient self-confidence and selfesteem, and a change in the incidences of adverse events.

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

Penile circumference was measured before, immediately after, and 30-90 days after the implant surgery. In the 400 patients, the implantation of the Pre-Formed Penile Silicone Block increased midshaft circumference from an average of 8.5 ± 1.2 cm to 13.4 ± 1.9 cm, a 56.7% increase (P<.001). Six to eight weeks postoperatively, 83% of the surveyed patients noted a 2-category improvement in their self-confidence and self-esteem, and upon long-term follow-up (2-6 years, mean 4 years), 72% patients maintained a 2-category improvement in their APPSSI score, and 81% of subjects reported "high" or "very high" levels of satisfaction with their surgical outcome.

The most frequently reported postoperative complications were seroma (4.8%), scar formation (4.5%), and infection (3.3%). 3% of patients experienced adverse events that necessitated device removal. There were no reports of any changes to sexual function, erections, or ejaculations.

## CONCLUSION

The subject device is identical in dimensions, design, materials, and technological characteristics and has the same intended use as the predicate device (K181387). It was determined that the subject device is as safe and effective as the predicate device because they have the same intended use and identical technological characteristics. Therefore, the subject device is substantially equivalent to the predicate device.
