Abstract

Organ manipulation devices for atraumatically grasping the surface of an organ and repositioning the organ to allow access to a location on the organ that would otherwise be substantially inaccessible. Methods of accessing a beating heart, retracting the heart using an organ manipulation apparatus, and stabilizing a surgical target area with a stabilizer. Both the organ manipulator and stabilizer are fixed to a stationary object which may be a sternal retractor. A system for performing beating heart coronary artery bypass grafting includes a sternal retractor, organ manipulator and stabilizer.

Claims

1. An organ manipulation apparatus comprising:

a suction assembly, wherein the suction assembly includes

a hollow shaft connectable to a first vacuum source;

a suction cup connected to the hollow shaft and configured to establish a relative negative pressure, via the vacuum source, in a space between the suction cup and an organ and to exert sufficient force on the organ to move the organ when the suction cup is moved after first being placed against the organ;

a clevis arranged to translate along a length of the hollow shaft; and

a roller comprising an elongated body with an axis of rotation substantially perpendicular to the length of the hollow shaft to permit rotational movement between the clevis and the hollow shaft; and

a tissue stabilizer configured to stabilize a coronary artery, wherein the tissue stabilizer includes

a heart contact member that includes one or more stabilizer feet, wherein each one of the stabilizer feet is configured to engage a surface of a heart, and each one of the stabilizer feet can be rotated; and

a device disposed to draw a vacuum through each one of the stabilizer feet.

2. The organ manipulation apparatus of claim 1, wherein the tissue stabilizer further comprises a maneuverable arm that connects the heart contact member via a base member to a tightening mechanism, wherein the maneuverable arm includes multiple articulating joints and tensioning the tightening mechanism freezes orientation of the maneuverable arm.

3. The organ manipulation apparatus of claim 2, wherein the device disposed to draw a vacuum comprises a manifold base, wherein each one of the stabilizer feet can be rotated with respect to the manifold base.

4. The organ manipulation apparatus of claim 2, wherein the suction assembly is secured to an articulating arm via a shaft protruding from the clevis.

5. The organ manipulation apparatus of claim 4, further comprising a support structure connected to one or both of the articulating arm opposite to the suction assembly and the maneuverable arm.

6. The organ manipulation apparatus of claim 1, wherein the suction assembly further comprises a bias member configured to exert a biasing force on the clevis in a direction along the length of the hollow shaft.

7. The tissue stabilizer of claim 1, wherein the one or more stabilizer feet are malleable so that a shape of each one of the stabilizer feet is variable by manual manipulation.
