AI Technical Summary
⚠Technical Problem
Current thermal ablation procedures for liver or renal tumors abutting the gastrointestinal tract are risky due to the potential for bowel perforation, and existing catheters are not practical for planar separation of organs, leading to complications like fluid overload and electrolyte imbalance.
⚗Method used
A balloon catheter with a planar, sheet-like configuration and temperature-resistant balloons, designed for easy maneuverability, to safely separate organs during thermal ablation procedures.
🎯Benefits of technology
The balloon catheter effectively separates organs, reducing the risk of perforation and minimizing side effects by maintaining organ separation during high-temperature procedures.

Abstract
A balloon catheter, comprising an elongate body having a proximal end and a proximal opening, a distal end and a distal opening, the proximal and distal openings defining an inner lumen therebetween, wherein the body defines an inner surface and an outer surface, a first internal channel positioned within the inner lumen and fluidly connected to at least one balloon positioned on the outer surface of the body at the distal end, wherein the balloon is configurable between an inflated state and a deflated state, and a second internal channel positioned within the inner lumen.
