Abstract
A retractor is configured to manipulate for vascular structures during minimally invasive surgical procedures such as mitral valve repair. A long wire has a spring loop at one end surrounded by a helical spring coil forming a toroidal ring. The spring maintains a circular shape while expanding and shrinking under manual control to a desired size for initiating and maintaining the retraction. The looping end of the spring wire is enclosed by the helical coil spring. The other end of the long wire is mounted through a frame with two hollow support arms carrying separate sides of the long wire and guiding them through a long support tube to a proximal end of the tube where each separate portion of the long wire attaches to a coupler. The coupler includes a handle or other push/pull mechanism to adjust the size of toroidal ring.
