Summary
The helical coiled-spring aneurysm clip
Area of Science:
- Neurosurgery
- Biomaterials Science
- Medical Device Development
Background:
- The helical coiled-spring aneurysm clip evolved from earlier designs by Mayfield and Scoville.
- Developmental challenges prompted a review of metals utilized in neurosurgical applications.
Purpose of the Study:
- To evaluate metals for neurosurgery implants.
- To establish standards for medical implants.
- To identify materials with enhanced strength and biocompatibility.
Main Methods:
- Historical review of aneurysm clip development.
- Evaluation of metal properties for neurosurgical implants.
- Assessment of tissue compatibility and MRI safety.
Main Results:
- The development process led to the selection of stronger, more biocompatible metals.
- These advanced metals were found to be safe for use during magnetic resonance imaging (MRI).
Conclusions:
- The evolution of the helical coiled-spring aneurysm clip drove advancements in neurosurgical implant materials.
- Improved metal selection enhanced both implant performance and patient safety, including MRI compatibility.
