A simple method for limiting angioplasty catheter balloon pressures

Area of Science:

• Cardiovascular Interventions
• Medical Device Safety
• Interventional Radiology

Background:

• Percutaneous angioplasty is a common procedure.
• Catheter balloons used in angioplasty are susceptible to rupture from over-inflation.
• Accurate monitoring of balloon inflation pressure is not consistently performed.

Purpose of the Study:

• To present a simple, cost-effective method for controlling balloon inflation pressures during percutaneous angioplasty.
• To reduce the risk of catheter balloon rupture due to over-inflation.

Main Methods:

• A novel, low-cost technique for pressure limitation during balloon inflation is described.
• The method requires no additional specialized equipment beyond standard angioplasty supplies.

Main Results:

• The described method effectively limits balloon inflation pressures.
• Implementation of this technique can prevent over-inflation and potential balloon rupture.
• The method is easily integrated into existing angioplasty workflows.

Conclusions:

• A simple and inexpensive method for limiting angioplasty balloon inflation pressure is feasible.
• This technique enhances the safety of percutaneous angioplasty procedures by mitigating rupture risk.
• Widespread adoption could improve patient outcomes and reduce complications associated with balloon over-inflation.
