Abstract
Disclosed is a device for isolating a cardiac surgical site. The device includes a first finger having a clinging accessory for attaching the first finger to a heart, a second finger having a clinging accessory for attaching the second finger to the heart, a first joint disposed on the first finger so that the first finger may rotate on a surface of the heart such that the rotation stretches a surgical site, a first stopper disposed on the first finger for preventing undesired rotation of the first finger to isolate the surgical site, and a link for coupling the first finger to the second finger. Also disclosed is a method of isolating a cardiac surgical site. The method includes the steps of disposing a first finger on a heart, clinging the first finger to the heart surface, disposing a second finger on a heart, clinging the second finger to the heart surface, and then rotating the first finger for achieving selective isolation of the heart surface.
