Safety: Number of Participants With Device Related Complications Primary · 21 +/- 7 Days

The primary endpoint of this study is the freedom from major device related complications. The safety endpoint will include an assessment of the safety of the EndoRotor when performing endoscopic necrosectomy. For the purpose of this study, the safety evaluation shall include complications associated with endoscopic necrosectomy through the 21 (+/-7) day follow-up period. Potential endoscopic complications include perforation and bleeding.

Effectiveness: Number of Participants With at Least 70% of Necrotic Debris Removed Secondary · 21 +/- 7 Days

Successful clearance of necrosis in the collection being treated during direct endoscopic necrosectomy where success is defined as at least 70% of the necrotic debris in the collection being treated is removed based on CT evaluation of the cavity at the 21 (+/-7) day follow up visit.

Mean Total Procedure Time to Achieve at Least 70% Reduction in Necrosis Secondary · Completion of all necrosectomy procedures per patient

Assessment of total procedure time to achieve clearance of necrosis for all procedures. Total procedure time is measured from scope-in to scope-out. EndoRotor time is measured from the start of EndoRotor use to the end of EndoRotor use.

Adequacy of Procedural Debridement: Mean Percent Necrotic Material Removed From the WOPN Cavity Per Procedure. Secondary · This outcome was assessed at the completion each necrosectomy procedure per participant. At the completion of all necrosectomy procedures for all participants, an overall mean percent necrotic material removed from the WOPN per procedure was calculated.

At the completion of each necrosectomy procedure the Investigator will visually inspect the WOPN cavity endoscopically and estimate the percent of necrosis that was removed from the cavity using EndoRotor. For each procedure, the initial amount of necrosis in the WOPN cavity is considered 100%.

Mean Number of Necrosectomy Procedures Required Per Participant to Achieve at Least 70% Reduction in Necrosis. Secondary · This outcome was assessed at completion of all necrosectomy procedures per participant. After completion of all necrosectomy procedures in all participants the overall mean number of procedures to achieve at least 70% reduction in necrosis was calculated.

The total number of necrosectomy procedures required per participant to achieve at least 70% reduction in necrosis from the WOPN will be assessed.

Quality of Life - Short Form 36-Item Health Survey Version 1 (SF-36v1), Physical & Emotional Composite Score Secondary · 21 +/- 7 Days

The SF-36v1 questionnaire measures functional health and well-being from a patient's point of view. The questionnaire assess eight health domains including: Physical Functioning, Role Limitations due to Physical Health, Role Limitations due to Emotional Problems, Energy/Fatigue, Emotional Well Being, Social Functioning, Pain, and General Health. Participants were asked to complete the questionnaire at the Baseline Visit and then again at the 21 Day Post Necrosectomy Follow-up Visit. The results of the questionnaire from the 21 Day Post Necrosectomy Follow-up Visit were then compared to those
