Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The LiVac Retractor and bevel device will be used during upper abdominal laparoscopic surgery on 10 patients to retract the liver and allow access to the target organs for surgery.

The retractor is placed between the liver and diaphragm and uses suction to retract the liver. The bevel allows passage of the suction tube through surgical ports

Summary
Brief summary
Current methods of retracting the liver during surgery (to allow sight of and access to target surgical organs) can be traumatic or painful, and can require additional surgical assistants. The LiVac Retractor System has been developed to retract and hold the liver by suction, therefore reducing trauma and the need for extra assistance.
This proof of concept study will assss how well the devices work during surgery and whether there are any safety issues.
