### d. Device Description

The Freedom Inguinal Hernia Implant is used to plug or patch a hernia opening. The implant is wholly manufactured from polypropylene. It is comprised of two polypropylene meshes and two small polypropylene rings. A multi looped shaped core fills the hernia opening while an underlay patch reinforces the defect and holds the implant in place. This underlay patch helps to prevent expulsion and rotation. Once the tissue defect is prepared, the implant is deployed into the defect area using the delivery device provided in the Freedom Inguinal Hernia Repair kit. The delivery device serves to compact the implant and provide access to the defect opening to aid implantation. Once deployed, the tissue contracts around the implant, gripping it in place. There are two different sizes of implants and corresponding delivery devices to accommodate different size defects. The implant and delivery device are provided sterile for single patient use.

### e. Indications for Use:

The Freedom Inguinal Hernia Implant is intended to reinforce soft tissues where weakness for open repair of inquinal hernias exists.

### g. Pre-Clinical Test Results:

In vitro, in vivo and biocompatibility tests were performed on the Freedom Inguinal Hernia Implant. The in vitro tests showed that the device meets pre-determined acceptance criteria or specifications that were based on the clinical demands placed on the device. The in vivo testing validated the implantation procedure and a survival study was performed that demonstrated the tissue incorporation of the implant. Results of the in vivo study were published in the journal of Artificial Organ (3). The biocompatibility testing showed the Freedom Inquinal Hernia Implant complies with the requirements for this device classification.

Cadaver studies were performed during the development of both the Freedom Inguinal Hernia Implant as well as the delivery device. These studies showed that the implant could be successfully deployed in the proper location and further validated the implantation technique. These results were considered in the final design configurations.

### h. Results of Clinical Experience:

Two groups of data from relevant clinical experience were collected and reviewed. The first group of patients (n=61) received custom implants that were fabricated from surgical polypropylene mesh by the implanting surgeon. This was a single center, single surgeon clinical experience. In these patients, the surgeon used both stainless steel and rigid plastic tubes to provide the slight dilation of the defect and access required to deliver the implant. Patients were followed for a minimum of 3 years after the date of implantation. One patient was lost to follow up due to unrelated heart failure death after 14 months. The results demonstrated that defect dilation with tubes and treatment with flower shaped implants was safe and effective for the treatment of inguinal hernias. After 3 years, there have been no reports of unresolved post operative complications, recurrences, or chronic discomfort in these patients. The diameters of the dilation tubes were the diameters of the Insightra Medical Delivery Device, that is subject of this premarket notification.

The second group of patients reviewed (n=30) received the Insightra manufactured implant that is the subject of this submission. The implant was delivered using standard open surgical techniques using a previous version of the Freedom Inquinal Hernia Delivery System. This delivery system was identical dimensionally to the delivery system that is included in this premarket notification. Follow-up ranged from perioperative to one year post-implantation. Of these 30 patients, 27 were followed for a year or more with a mean followup of 25 months (ranging 11 to 36 months). There were no reports of unresolved perioperative complications, tissue injury or spermatic cord complications associated with this device.

In exceptional cases, an additional flat polypropylene mesh has been deployed to cover the inquinal floor, over the Freedom Inquinal implant that obliterates the hernia opening. This further reinforces the inguinal canal at the hernial protrusion when the groin structures appear obviously weak. The onlay flat mesh is not sutured or fixed to the inguinal structures, instead only connected to the central core of the Freedom Inguinal implant with a single polypropylene suture. Previous experiences of using this procedural variant produced, with the exception of some very seldom reported discomfort during the early postoperative stage, no unusual symptoms reported by patients who received the onlay patch in addition to the Freedom Inguinal implant.

{3}------------------------------------------------

For all patients in both groups reviewed with at least one year followup (n= 78) who received this dilation delivery technique, there were no reports of tissue tearing injury or spermatic cord injury. There have been no reports of dislodgements, unresolved post operative complications, chronic discomfort or recurrence of hernia. For the twenty seven patients in the second group who were followed for a year or more and received the Insightra Medical manufactured implant, there were no reports of spermatic cord injury or compression complications due to device rotation or inappropriate sizing.

The second study group by Amato (n=30) is summarized along with a third independent investigator sponsored study by Petrella, in the device labeling. Descriptive tables are included in the device "Technique Guide" as follows;

These clinical studies followed cohorts of patients (total n=54) that met the following inclusion/exclusion criteria:

#### 510(k) Summary Conclusion: i.

In summary, the Insightra Freedom Inquinal Hernia Implant path through the 510(k) requlatory analysis is as follows:

- The Insightra Freedom Inquinal Hernia Implant and the Bard Perfix Plug and Ethicon Prolene Hernia System predicate devices, are all intended for use in the repair of inguinal hernia defects.
- The Insightra Freedom Inguinal Hernia Implant has similar key technological . characteristics as the Bard Perfix Plug and Ethicon Prolene Hernia System devices. All three are manufactured from polypropylene mesh, all use mesh patch reinforcements, and all are inserted into the hernia defect without the need for suture;
- Although the Insightra Freedom Inguinal Hernia Implant and predicate devices have a . minor technological difference in terms of the method of delivery, this difference does not raise any new types of safety or effectiveness questions. In addition, valid scientific methods exist for assessing the effects of the differences in delivery methods. Preclinical and clinical data demonstrate that these devices are substantially equivalent.
