Abstract: An introducer for a blood vessel cannula has a main elongate portion adapted for insertion into a blood vessel cannula. A first end of a transition portion is adjacent to and extends from the main elongate portion. The first end of the transition portion has an outside diameter larger than an outside diameter of a second end of the transition portion. A first end of an extended portion is adjacent to and extends from the second end of the transition portion and the first end of the extended portion has an outside diameter that is larger than an outside diameter of a second end of the extended portion. A distal end portion is adjacent the second end of the extended portion and has an aperture. A lumen extends through the aperture, main elongate portion, the transition portion, the extended portion, and the distal end portion.

Abstract: An intravascular balloon occlusion device according to the invention is shown. The device is ideally suited for use in a coronary artery bypass graft procedure. The device includes a body having at least one selectively inflated balloon provided on the distal end thereof. Preferably, the body is a closed end body so that fluid can only flow from the proximal end of the body into the balloon. In use, the distal end of the body and the balloon are inserted into an aperture provided in the aorta. The balloon is inflated and then the device is retracted until the balloon seats against the incision or aperture in the aorta, thereby effectively sealing the aperture from the blood flow through the aorta, but not occluding blood flow through the body of the aorta itself. Next, the graft vessel is telescopically positioned on the occlusion device and mounted to the aorta. Once the vessel is secured thereto, the balloon is deflated and then the occlusion device is retracted from both the aorta and the graft vessel. Finally, the second end of the graft vessel is mounted to the appropriate coronary artery.

Abstract: An electro-stimulation device includes a pair of electrodes for connection to at least one location in the body that affects or regulates the heartbeat. The electro-stimulation device both electrically arrests the heartbeat and stimulates the heartbeat. A pair of electrodes are provided for connection to at least one location in the body that affects or regulates the heartbeat. The pair of electrodes may be connected to an intravenous catheter for transvenous stimulation of the appropriate nerve. A first switch is connected between a power supply and the electrodes for selectively supplying current from the power supply to the electrodes to augment any natural stimuli to the heart and thereby stop the heart from beating. A second switch is connected between the power supply and the electrodes for selectively supplying current from the power supply to the electrodes to provide an artificial stimulus to initiate heartbeating. In another aspect, the invention is directed to a method for arresting the beat of a heart in a living body comprising the steps of connecting the pair of electrodes to at least one location in the body that affects or regulates the heartbeat and supplying an electrical current to the electrodes of sufficient amplitude and duration to arrest the heartbeat. The device may also serve to still the lungs by input to a respirator or by stimulation of the phrenic nerve during surgical procedures.

Abstract: A method of pressurizing the right ventricle of the heart. The method includes providing a multi-lumen cannula. The multi-lumen cannula includes a first sub-cannula and a second sub-cannula. The first sub-cannula includes a proximal end, a distal end, a lumen extending between the proximal and distal ends, and proximal and distal fluid apertures formed in the lumen. The second sub-cannula includes a proximal end, a distal end, a lumen extending between the proximal and distal ends, and proximal and distal fluid apertures formed in the lumen. The distal fluid apertures of the two lumens are spaced from one another along the axial length of the multi-lumen cannula. The method further includes inserting the cannula into the vasculature system of a patient so that the distal fluid aperture of the lumen of the second sub-cannula is received in one of the right atrium, the superior vena cava, and the inferior vena cava. The distal fluid aperture of the lumen of the first sub-cannula is received in the right ventricle. The method of pressurizing the right ventricle still further includes fluidly connecting the proximal fluid apertures of the first and second sub-cannulas to a fluid conducting pump for moving fluid through the two sub-cannulas.

Abstract: A cannula for conducting fluid to a body includes a cannula body having proximal and distal ends and a lumen extending therebetween. The lumen is adapted to receive the fluid flowing therethrough. The cannula also includes a cannula tip, which is coupled to the distal end of the cannula body. The canula tip includes a side wall having a plurality of fluid outlets formed therein. Each fluid outlet is directed toward the proximal end of the cannula body to reverse the flow of fluid exiting the cannula by an obtuse angle from the original direction of flow.

Abstract: The multi-lumen cannula according to the invention is preferably formed from two separate sub-cannulas, a portion of which are adhered to one another. Preferably, the adhered portions of the sub-cannulas are deformed such that the assembled multi-lumen cannula is substantially circular in cross section throughout the adhered portions of the sub-cannulas. In addition, the septum separating the multiple lumens of the cannula is preferably reinforced so that the multi-lumen cannula can accommodate dramatically different fluid pressure within the cannula without deformation of the septum. This cannula is ideally suited for use in a variety of left-heart and right-heart assist cardiac surgical procedures, especially minimally invasive procedures.

Abstract: A cardioplegia management system comprises an inlet tube adapted for connection to a source of cardioplegic fluid, and at least two supply tubes extending from the inlet tube and in communication therewith, whereby fluid passing through the inlet will be directed to the supply tubes. The system also includes a base, and clamps associated with the supply tubes. Each of the clamps is mounted on the base in a position to selectively clamp and unclamp its respective supply tube, thereby selectively blocking or allowing flow of fluid through the supply tubes.

Abstract: An arterial cannula which includes a diverting side hole which simultaneously perfuses blood to the body and the lower extremity. Two barbs on the cannula exterior position the diverting hole just inside the blood vessel and prevent the back wall of the blood vessel from blocking the diverting hole. A transparent flash chamber on the proximal end of the cannula provides a visual indication of the entrance of the diverting side hole into the blood vessel. When the diverting hole enters the blood vessel, blood immediately fills the flash chamber.
