Introduction of two new laparoscopic nooses

Area of Science:

• Surgical Innovation
• Vascular Surgery
• Medical Device Development

Background:

• Temporary occlusion of tubular structures is crucial in various surgical procedures.
• Existing methods may require specialized, bulky laparoscopic instruments.
• Need for cost-effective and readily available occlusion devices exists.

Purpose of the Study:

• To introduce novel devices for temporary occlusion of tubular structures.
• To demonstrate a method for atraumatic engagement of vessels.
• To provide an alternative to traditional bulky instruments in surgical fields.

Main Methods:

• Devices constructed by combining a double-looped suture with a catheter segment.
• Creation of a terminal noose for engaging tubular structures.
• Utilizing readily available operating room materials like polyfilament suture and catheters.

Main Results:

• The devices enable temporary and atraumatic occlusion of vessels and other tubular structures.
• Proximal and distal control of short segments is achievable.
• Eliminates the need for bulky laparoscopic instruments in the operative field.

Conclusions:

• The described devices offer a simple, cost-effective solution for temporary tubular structure occlusion.
• These devices can be easily fabricated from existing surgical supplies.
• Potential to enhance surgical efficiency and reduce procedural costs.
