The goal of this clinical trial is to evaluate the safety of the investigational device, Regenn® Negative Pressure Therapy System (Regenn® Therapy), a form of Negative Pressure Wound Therapy (NPWT), in the post-operative surgical wounds of patients undergoing lumbar spinal fusion surgeries. The main questions the study aims to answer are:
- The device-related serious adverse event rate.
- Patient post-operative pain as assessed using a validated pain measurement scoring system.
- The number and type of adverse events.
- The rate of delayed seroma formation.
Participants will
- Be screened for their suitability to participate in the investigational study using questions about their health, medical history, and current medications.
- Undergo a physical exam, an assessment of patient vital signs and routine blood analyses.
- Complete an Informed Consent Form if selected to participate in the investigational study.
- Be randomly assigned to the different study arms.
- Not change the operation of their respective device or to disturb components of their device.
- Notify their surgeon or designated healthcare provider should they have any questions or encounter any issues with their device.
- Attend two post-operative visits at approximately one month and three months.

Experimental: Treatment Arm
This group will receive the study device, Regenn® Negative Pressure Therapy System, a form of Negative Pressure Wound Therapy (NPWT). Regenn® Therapy manages the surgical wound by the application of reduced pressure therapy (i.e., mild vacuum). Reduced pressure therapy is controlled by a hand-sized, battery-operated pump and is delivered by an attached small, dressing that the surgeon places in the surgical wound at the end of the surgery. Reduced pressure therapy is applied while the patient recovers from surgery.

Active Comparator: Control Arm
This group will receive the control device, also a form of Negative Pressure Wound Therapy (NPWT), which manages the surgical wound by the application of reduced pressure therapy (i.e., mild vacuum). Reduced pressure therapy is controlled by a hand-sized, battery-operated pump and is delivered by a small tube connected to a wound dressing placed over the closed surgical wound at the end of the surgery. Reduced pressure therapy is applied while the patient recovers from surgery.

- Device-related Serious Adverse Event Rate [ Time Frame: Post-operative follow ups at 2-8 weeks and 3-6 months. ]The device-related serious adverse event rate associated with the use of the investigational device and the comparator device. Wound complications requiring surgical intervention, such as wound dehiscence, will be the primary indicator of blood supply at the wound site, damage to the surrounding tissue, and progression of wound healing.
- Post-operative Pain Profile [ Time Frame: Post-operative up to the 3-6 month follow up visit. ]Post-operative pain will be assessed using the Numerical Rating Scale (NRS), a validated pain measurement scoring system with a pain rating scale of 0 - 10, where zero means "No pain" and 10 means "The worst pain imaginable"
- Adverse Events Related to the Investigational Device [ Time Frame: Post-operative follow ups at approximately one month and three months. ]The number and type of adverse events associated with the use of the investigational device. Assessment will include wound complications not requiring surgical intervention, device complications, medical complications and infections complications.
- Delayed Seroma Formation Rate [ Time Frame: Post-operative follow up at 2-8 weeks (at the surgeon's discretion) and at 3-6 months (required). ]Delayed seroma formation will be assessed by ultrasound imaging during post-operative follow up visits.

Ages Eligible for Study: | 18 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria (must meet ALL):
- Subject has provided written informed consent on a form reviewed and approved by the Institutional Review Board for the clinical site.
- The subject is 18 - 80 years old.
-
The subject has Spondylolisthesis of Meyerding Grade II or less, or has Degenerative Disc Disease (DDD) accompanied by back pain with or without leg pain at a level between L1 and S1 confirmed by history and radiographic assessment. DDD is determined to be present if one or more of the following are noted:
- Instability (defined as angulation ≥ 5 degrees and/or translation ≥ 3mm on flexion/extension radiographs;
- Osteophyte formation of facet joints or vertebral endplates;
- Decreased disc height, on average by >2mm, but dependent upon the spinal level;
- Scarring / thickening of ligamentum flavum, annulus fibrosis, or facet joint capsule;
- Herniated nucleus pulposus;
- Facet joint degeneration / changes; and/or
- Vacuum phenomenon.
- Female subjects of childbearing potential must not be pregnant or nursing and must agree to use of contraception for the study duration. Female subjects who are surgically sterile or post-menopausal are exempt from having a pregnancy test and birth control.
- The subject is willing and able to comply with the protocol mandated follow-up visits and testing regimen.
Exclusion Criteria (candidates meeting ANY of the following at the time of the study procedure are NOT eligible):
- Subject is unable or unwilling to provide informed consent or is unable to conform to the study protocol follow-up procedures and visits.
