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. |

DETAILED DESCRIPTION The present invention provides a device and method for isolating a heart surface, particularly, the surface of a beating heart during cardiovascular surgery.
The device utilizes rotation to attach to the heart surface and then spread the heart which isolates the spread portion of the heart for surgery.
Disclosed is a device for isolating a cardiac surgical site.
The device generally comprises a first finger (which may be cylindrical) having a clinging accessory for attaching the first finger to a heart.
Furthermore the device could comprise 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 said rotation stretches a surgical site, and a link for attaching the first finger to the second finger.
In addition, a first stopper may be disposed on the first finger for preventing undesired rotation of the first finger to isolate the surgical site.
The accessory for attaching could comprise a plurality of tines, a plurality of suction points, or a rough textured surface such as a surface similar to sandpaper, for example.
In addition, the first joint or a second joint (disposed on the second finger) could comprise a rotatable handle coupled in a sleeve.
Furthermore, the first stopper or a second stopper (disposed on the second finger) could be configured such that the rotatable handle comprises at least one notch and the sleeve has at least one rib.
Likewise, the first stopper or the second stopper (disposed on the second finger) could be configured such that the rotatable handle comprises at least one rib and the sleeve has at least one notch.
The handle could comprise an O-ring groove for securing an O-ring about an end of the handle.
The link could comprise a ball and socket joint disposed between the first finger and the second finger for providing multi-axis articulation of the first finger and the second finger, as well as a first attachment bar coupled between the first handle and the ball and socket joint, and a second attachment bar coupled between the second handle and the ball and socket joint
