ABSTRACT:
A torsion spring with a coil portion having extensions extending from the ends of the coil for receiving forces for torquing the spring. The spring provides a more balanced stress distribution about the coil which in the preferred embodiment include a region of increased cross-sectional area on one side of the coil and a region of decreased cross-sectional area across the coil from the region of increased cross-sectional area and smooth contouring of the coil between these two regions. A particular use of the torsion spring of the present invention is in a torsion spring-type aneurysm clip for providing more uniform stress distributions about the coil portion of the aneurysm clip and for permitting the aneursym clip to open wider so that it may be used on larger aneurysms.
