November 21, 2019 updated by: Alesi Surgical Ltd.

Open Label, Single Center, Randomized Study Evaluating the Feasibility of the Ultravision™ Visual Field Clearing System in Low Pressure Laparoscopic Cholecystectomy Compared To AirsealL® IFS

This post-market clinical study is designed to evaluate the effectiveness of the Ultravision™ System when compared to the Airseal® iFS within an approved indication for use, namely laparoscopic cholosystectomy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The primary hypothesis being tested in this study is that Ultravision facilitates the utilization of lower pneumoperitoneal pressures whilst maintaining an adequate visual field throughout the procedure with low demand for CO2 replenishment to maintain pneumoperitoneal pressure. Comparisons in terms of surgical field visualization, procedure times, and CO2 consumption will be conducted in order to determine whether or not any clinical benefits are derived from the use of the Ultravision™ System compared to the Airseal® iFS. Low pressure laparoscopy for this study is set at 10mmHg. This is a prospective, open-label, randomized controlled study. The study will include two study arms. Patients undergoing laparoscopic cholecystectomy will be randomized to either "Ultravision" (study arm 1) or Airseal® iFS (study arm 2). Both groups will conduct the procedure at 10mmHg, considered to be low pressure/low impact laparoscopic surgery. The study will enroll 30 patients, 15 per group. Both devices are being used according to their cleared label claims.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
