A device to facilitate post-operative sternal closure by twisting the opposite end regions of the suture wire together comprises spaced guides in the form of limbs (1 and 2) with passageways (3 and 4) through which the proximal wire ends (12) and (13) may be fed and a cross-piece (7) transversely positioned with respect to said guides whereby, in use, the wire end regions may be bent across and supported by the cross-piece. The cross-piece includes a discontinuity (8) with a spacing adapted to be less than the thickness of wire. As the tension in the wire increases during the course of the twisting motion a point will be reached when the wire end regions forcefully deform the cross-piece (7) enabling the wires to pass through the discontinuity. Thus an indication is given when a maximum tension is reached.

An organ manipulator including at least one suction member or adhesive disc mounted to a compliant joint, a flexible locking arm for mounting such suction member or compliant joint, and a method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps. In preferred embodiments, a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery. As the retracted heart beats, the compliant joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not compromised. The suction member conforms or can be conformed to the organ anatomy, and its inner surface is preferably smooth and lined with absorbent material to improve traction without causing trauma to the organ. The compliant joint can connect the member to an arm which is adjustably mounted to a sternal retractor or operating table. The compliant joint can be a sliding ball joint, a hinged joint, a pin sliding in a slot, a universal joint, a spring assembly, or another compliant element. In preferred embodiments, the method includes the steps of affixing a suction member to a beating heart at a position concentric with the heart's apex, and applying suction to the heart while moving the member to retract the heart such that the heart has freedom to undergo normal beating motion at least in the vertical direction during retraction.

The present invention relates to a new non-invasive method for inducing angiogenesis and more particularly coronary angiogenesis wherein an operator applies localized percussion upon the upper torso proximate an ischemic myocardial region, whereby the percussive forces penetrate to cause sheer stresses to the endothelium of the coronaries which lie thereupon, and thereby cause new coronary growth by virtue of endogenous liberation of beneficial angiogenic mediators. A pair of vibratory contacts are advantageously applied to rib-spaces to either side of the sternum (or alternatively to the upper back), where-after percussion is applied at the resonance frequency of the heart / epimyocardium at a displacement amplitude of 0.1 mm-15 mm (preferably greater than 1 mm), such as to maximize an internal oscillatory effect. The system is also adaptable for cerebral and peripheral vasculature applications. Ultrasonic imaging may optionally be utilized to direct percussive therapy.
