Abstract

A system for manipulating and supporting a beating heart during cardiac surgery, including a gross support element for engaging and supporting the heart (the gross support element preferably including a head which is sized and shaped to cradle the myocardium of the left ventricle”), a suspension head configured to exert lifting force on the heart when positioned near the apical region of the heart at a position at least partially overlying the right ventricle, and a releasable attachment element for releasably attaching at least one of the gross support element and the suspension head to the heart. The releasable attachment element can be a mechanical element (such as one or more staples or sutures'"'"') or an adhesive such as glue. Alternatively, the system includes a suspension head and a releasable attachment element for releasably attaching it to the heart, but does not include a gross support element.

Claims

1. A manipulation system for cardiac surgery comprising:

a suspension head having a periphery;

extensions extending outward from said periphery of said suspension head; and

releasable attachment means for releasably attaching said extensions to the heart.

2. The manipulation system of claim 1, wherein said suspension head comprises a cup.

3. The manipulation system of claim 2, wherein said cup comprises a flexible wall.

4. The manipulation system of claim 3, wherein said cup further comprises a flexible rim.

5. The manipulation system of claim 2, wherein said cup comprises a flexible rim.

6. The manipulation system of claim 2, wherein said cup comprises an apex, said apex being attached to an arm.

7. A manipulation system for cardiac surgery comprising:

a suspension head comprising a cup having a flexible wall and a flexible rim; and

releasable attachment means, extending outside a periphery of said suspension head, for releasably attaching said cup to the heart.

8. The manipulation system of claim 7, wherein said cup further comprises an apex, said apex being attached to an arm.

9. A manipulation system for cardiac surgery comprising:

a suspension head adapted to attach to a surface of the heart by suction; and

releasable attachment means comprising at least one mechanical or chemical means for releasably attaching said suspension head to the heart, wherein said suspension head is configured to exert lifting force on the heart, and wherein said releasable attachment means further assure that said suspension head does not become unexpectedly detached from the heart when attached to the heart by the releasable attachment means.
