A MULTI-CENTER, PROSPECTIVE, RANDOMIZED, CONTROLLED STUDY TO EVALUATE PHYSICIAN PREFERENCE RELATED TO THE USE OF THE SURGIQUEST AIRSEAL INSUFFLATION SYSTEM (AIS) VS. CONVENTIONAL INSUFFLATION SYSTEMS (CIS) FOR THE MANAGEMENT OF PNEUMOPERITONEUM DURING ROBOTIC PARTIAL NEPHRECTOMY

A prospective, randomized, controlled multi-center clinical Study designed to evaluate Physician Preference related to the use of the SurgiQuest AirSealTM Insufflation System (AIS) vs. Conventional Insufflation Systems (CIS) for the Management of pneumoperitoneum during Robotic Partial Nephrectomy. Subjects will be randomized in a 1:1:1 treatment device to control ratio into one of three (3) different study arms: 1) AIS @ 12mmHg pressure, 2) AIS @ 15mmHg pressure, and 3) CIS @ 15mmHg pressure. 189 randomized subjects distributed in three arms of 63 patients. The three study sites are targeted to enroll 63 patients each, 21 patients in each of the three (3) study arms. It is expected that this will take up to 6 months.

Inclusion Criteria:

1. 18 to 80 years of age;
2. Capable and willing to give informed consent;
3. Acceptable candidate for an elective, non-emergent robotic partial nephrectomy;

Exclusion Criteria:

Subjects will be excluded from participating in this Study if they meet any of the following criteria prior to initiation of the endoscopic procedure 1.Advanced refusal of blood transfusion, if necessary; 2.Active systemic or cutaneous infection or inflammation; 3 Pre-existing immunodeficiency disorder and/or chronic use of systemic steroids; 4.Uncontrolled diabetes mellitus 5.Known, significant history of bleeding diathesis, coagulopathy, von Willebrand's disease or current platelet count < 100,000 cells/mm3, baseline INR ≥1.8, or fibrinogen level less than 150 mg/dl (if received a fibrinolytic agent within prior 24 hours); 6.Severe co-existing morbidities having a life expectancy of less than 30 days; 7.Currently involved in any other investigational clinical Studies; 8.Significant anemia with a hemoglobin level less than 10 g/dL or a hematocrit less than 30%; 9.Females who are pregnant, planning to become pregnant within 3 months of the procedure, or lactating; 10.Extreme morbid obesity (BMI greater than 45 kg/m2) or underweight (BMI less than 20 kg/m2); 11. Patients presenting with Ascites
