Summary
Kinking of guidewires during procedures using the "Doc" device is common. Two guidewire torque devices can easily straighten the kinked proximal end of the guidewire.
Area of Science:
- Interventional Cardiology
- Medical Device Engineering
Background:
- The use of extension devices like the "Doc" with guidewires is common in interventional procedures.
- The tapered proximal tip of guidewires is prone to kinking when using certain extension devices.
Purpose of the Study:
- To describe a common complication during guidewire extension procedures.
- To present a simple method for correcting guidewire kinking.
Main Methods:
- Observation of guidewire behavior during procedures involving the "Doc" device.
- Application of two guidewire torque devices to a kinked guidewire.
Main Results:
- Kinking of the proximal guidewire end frequently occurs when extending with the "Doc" device.
- Straightening the kinked guidewire is effectively achieved using two torque devices.
Conclusions:
- Guidewire kinking is a recognized issue with the "Doc" device.
- A practical technique using dual torque devices resolves guidewire kinking efficiently.
