Pre-operative Inclusion Criteria The Subject: 1. is an adult ≥ 18 years old of either gender 2. is able to provide their own informed consent Protocol: AHS.2012.Prevena.Cooper.01 v 4.0 Confidential/Property of KCI USA, Inc. Page 6 of 71 3. will undergo open renal transplant surgery within the next 30 days 4. will require a surgical incision able to be covered completely by the PIMS dressing 5. is pre-operatively assessed to undergo a procedure with a CDC Wound Classification of: 1. Class I (Clean): An uninfected operative wound in which no inflammation is encountered and the respiratory, alimentary, genital, or uninfected urinary tract is not entered \- OR - 2. Class II (Clean Contaminated): An operative wound in which the respiratory, alimentary, genital, or uninfected urinary tract are entered under controlled conditions and without unusual contamination 6. is willing and able to return for all scheduled and required study visits 7. if female, must test negative on serum pregnancy test 8. if a female of child-bearing potential, must be willing to utilize an acceptable method of birth control (e.g., birth control pills, condom with spermicide, diaphragm with spermicide, implants, IUD, injections, vaginal rings, hormonal skin patch, etc.) for the duration of study participation 9. is not concurrently enrolled in a clinical trial which may impact subject health or the surgical incision site Intra-operative Inclusion Criteria Subjects must meet the following intra-operative inclusion criteria to be eligible for randomization. The Subject: 1. continues to meet all pre-operative inclusion criteria 2. has undergone a Class I or II CDC Wound Classification procedure resulting in a closed surgical incision able to be covered completely by the PIMS dressing Pre-operative Exclusion Criteria The Subject: 1. has a BMI \< 18.5 kg/m2 and \> 40 kg/m2 2. has a systemic infection at the time of open renal transplant surgery 3. has a remote-site skin infection at the time of open renal transplant surgery 4. is preoperatively assessed to undergo a procedure with a CDC Wound Classification of: 1. Class III (Contaminated): Open, fresh, accidental wounds, and/or major breaks in sterile technique or gross spillage from the gastrointestinal tract \- OR - 2. Class IV (Dirty-Infected): Old traumatic wounds with retained devitalized tissue and those that involve existing clinical infection or perforated viscera 5. has a known allergy or hypersensitivity to silver, or drape materials that contain acrylic adhesives Intra-Operative Exclusion Criteria Subjects who meet any of the following intra-operative exclusion criteria are considered screen failures and are not eligible for randomization. The Subject: 1. is found to meet any of the pre-operative exclusion criteria 2. has obvious contamination of the surgical incision 3. requires external surgical drains that will be covered by the PIMS dressing 4. is determined to have a CDC Wound Classification of: 1. Class III (Contaminated): Open, fresh, accidental wounds, and/or major breaks in sterile technique or gross spillage from the gastrointestinal tract \- OR - 2. Class IV (Dirty-Infected): Old traumatic wounds with retained devitalized tissue and those that involve existing clinical infection or perforated viscera Protocol: AHS.2012.Prevena.Cooper.01 v 4.0 Confidential/Property of KCI USA, Inc. Page 8 of 71 5. requires a transfusion, has disseminated-intravascular coagulopathy (DIC) or other medical or surgical conditions during open renal transplant surgery deemed by the Investigator to pose a prohibitively high risk for surgical re-exploration 6. is deemed unable to continue in the study by the Investigator as the Subject's safety or well-being may be jeopardized.
