The subject was on or suspected to be placed on chemotherapy medications during any part of the study 4. The subject's Body Mass Index (BMI) was greater than 40 kg/m2 5. The subject had cirrhosis of the liver and/or ascites 6. Subject was American Society of Anesthesiology Class 4 or 5 7. Subject was known to be infected with human immunodeficiency virus (HIV) 8. Subject had a life expectancy of less than 2 years at the time of enrollment 9. Subject had any condition that, in the opinion of the Investigator, precluded the use of the study device, precluded the subject from completing the follow-up requirements 10. Subject's hernia repair utilized intraabdominal mesh placement 11. Subject had a surgical wound classified as Class II (Clean-Contaminated), Class III (Contaminated) or Class IV (Dirty-Contaminated) as defined by the CDC (Appendix 4 of the protocol) 12. Subject had an active or latent systemic infection 13. Subject required surgical bridge repair as the sole repair 14. Subject was pregnant or had plans to become pregnant during the study period or was breastfeeding 15. Subject had enrolled in another clinical study within the last 30 days 16. Subject was part of the site personnel directly involved with this study 17. Subject had a known allergy to the test device or component materials (patients with known allergies to tetracycline hydrochloride or kanamycin sulfate were avoided). |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Hernia Recurrence Rate | Hernia recurrence rates will be assessed by physical examination at each study visit through 60 months. A recurrent hernia will be defined as any hernia identified or confirmed by the investigator, during any study follow-up visit, in approximately the same position as the hernia repaired in the study procedure. Potential hernias identified via incidental magnetic resonance imaging (MRI) or computed tomography (CT) scan will be evaluated by the operating surgeon for clinical significance and confirmation of hernia recurrence. | 60 Months | |
Primary | Surgical Site Infections | Infections at the surgical site will be assessed by physical examination at each study visit through 60 months. If an infection is suspected, a routine culture, obtained via each site's standard protocol, should be obtained to determine cell count and type (i.e. yeast, gram positive or gram negative bacteria, or other). If genus and species of the culture are identified as part of the routine practice at the site, that information should be recorded. Classification will follow the CDC guidelines for superficial and deep surgical site infections | 60 Months | |
Secondary | Pain Visual Analog Scale | Mean change in self-reported pain measured on a Visual Analog Scale between Baseline and 60-month follow up. Scores are measured on a scale from 0.0 to 10.0 centimeters and marked on a line by the subject; lower values correspond with low pain perception. The outcome measure is presented as the mean of the absolute difference between the pain perception at Baseline and the pain perception at 60-month follow up. A negative score means a decrease in pain perception. | 60 Months | |
Secondary | Device Related Adverse Events | Incidence of device related adverse events: number of subjects with one or more possibly or definitely device related adverse events. The term "incidence" is an error and is reported here as the rate of device related adverse events. | 60 Months | |
Secondary | Rate of Re-operation Due to the Index Hernia Repair | Rate of re-operation due to the index hernia repair; the proportion of subjects with post-procedure re-operation due do the index hernia repair. | 60 Months | |
Secondary | Carolinas Comfort Scale® (CCS) | Each scale score (sensation of mesh, pain or movement limitations) ranges from 0-5 and is a summation of scores across the domains. Therefore, the Total CCS Score ranges from 0-115 and is the average of the 3 scale scores. Low scores represent fewer symptoms or difficulties.
Absolute values of the Total CCS Score at 1-Month follow-up, at 3-Month follow-up, at 6-Month follow-up, 12-Month follow-up, 18-Month follow up, at 24-Month follow-up, 36-Month follow-up, 48-Month follow-up, and 60-Month follow-up are reported. The absolute value at Baseline, or a change in self-reported quality of life measured by Carolinas Comfort Scale® cannot be reported, as subjects had incorrectly answered the questions on Sensation of Mesh at Baseline where no Phasix Mesh was yet implanted, thereby creating a bias in the results. |
60 Months | |
Secondary | SF-12 Questionnaire | The Short Form (SF)-12 version 2 (v2) is a multi-purpose, twelve item health survey that measures seven domains of health: general health, physical functioning, role limitations due to physical health (role-physical), role limitations due to emotional problems (role-emotional), bodily pain, vitality and mental health and social functioning. The SF-12v2 yields scale scores for each of these seven health domains, and two summary measures of physical and mental health: the physical component summary (PCS) and mental component summary (MCS). The scores range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health. | 60 Months | |
Secondary | Surgical Procedure Time as Measured From Incision to Closure | Surgical procedure time as measured from incision to closure (skin to skin) | 1 day | |
Secondary | Length of Hospital Stay | Time in days from hospital admission to discharge | 35 days |
