Abstract: A transseptal left atrial cannulation system which provides drainage of left atrial blood without the need for thoracotomy. A guide wire and a long needle assembly are inserted into a catheter. A cannula rides over the exterior of this catheter. The guide wire may be advanced past the needle assembly and through a catheter through the distal end of the catheter to assist in directing the system to the right atrium. The cannulation system is inserted in a femoral vein located in the groin. Both the guide wire and needle assembly are long enough to allow a substantial length to extend out of the body at the groin for manipulation even when the distal ends of the guide wire and needle assembly are positioned in the heart. When the catheter distal end is positioned adjacent the septum in the right atrium, the guide wire is withdrawn from the catheter orifice and the needle assembly moves past the guide wire and through the catheter orifice to a position adjacent to the septum. The needle pierces the septum and the catheter moves over the needle assembly to further dilate the septal hole. The cannula attached to the catheter also moves through the septal hole, further dilating it, and resting with the holes in the left atrium. The guide wire, the needle assembly, and the catheter are withdrawn from the cannula. Oxygenated blood from the left atrium drains through the cannula to the extracorporeal pump and back to the body through an arterial cannula.

Abstract translation: 经心脏左心房插管系统，无需胸廓切开术即可提供左心房血液的引流。 导丝和长针组件插入导管中。 套管穿过该导管的外部。 引导线可以经过针组件并穿过导管穿过导管的远端，以帮助将系统引导到右心房。 插管系统插入位于腹股沟的股静脉。 引导线和针组件都足够长，以使即使当导丝和针组件的远端定位在心脏中时，相当长度也能在腹股沟处延伸出体外，以进行操作。 当导管远端邻近右心房的隔膜定位时，导丝从导管孔中取出，针组件移动通过导丝并穿过导管孔移动到与隔膜相邻的位置。 针刺穿隔膜，导管移动到针组件上，以进一步扩大隔膜孔。 连接到导管的插管也可以穿过隔膜孔，进一步扩张，并与左心房中的孔一起休息。 引导线，针组件和导管从插管中取出。 来自左心房的氧合血液通过套管排出到体外泵并通过动脉插管返回到身体。

Abstract: A cannula assembly including a tube cannula and a hollow introducer needle. At the proximal end of the cannula are three fittings: first, a first luer fitting affixed to the proximal end of the tube cannula; second, a luer fitting removably attached to the first luer fitting, this second luer fitting having a first air porous water locking plug at a proximal end penetrated by the needle; and, third, a needle handle removably attachable to the second luer fitting. The proximal end of the needle handle is blocked also by a second air porous water blocking plug. The second plug prevents escape of blood from the hollow needle upon penetration of the arterial wall. The first plug controls the rate of flow of blood to the cannula tube and allows clamping of the tube after withdrawal of the introducer needle and prior to connection to a cardioplegia supply line.

Abstract: A single stage catheter which is used in open heart surgery to by-pass blood from the heart to a life support machine. The single stage catheter has a spiral lead flute for insertion into the inferior vena cava of the heart and a root section with multiple openings to be positioned in the right atrium of the heart. The flutes of the spiral lead to small quadrant openings in the end of the root section which also has long and short axial slot openings leading to the interior of the catheter. An obturator is designed to block the long and short axial slots during insertion to allow flow only through the quadrant openings to the interior of the obturator.

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 translation: 示出了根据本发明的血管内球囊闭塞装置。 该装置非常适用于冠状动脉旁路移植手术。 该装置包括具有设置在其远端上的至少一个选择性膨胀的气囊的主体。 优选地，主体是封闭的端体，使得流体仅能够从主体的近端流入气囊。 在使用中，身体的远端和气囊被插入设置在主动脉中的孔中。 气囊膨胀，然后将装置缩回直到气囊抵靠主动脉中的切口或孔，从而有效地将孔径从通过主动脉的血流密封，而不阻塞通过主动脉本身的血液的血流。 接下来，移植物容器可伸缩地定位在闭塞装置上并安装到主动脉。 一旦容器固定到其上，气囊就放气，然后闭塞装置从主动脉和移植血管两端缩回。 最后，移植血管的第二端安装在合适的冠状动脉上。

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.
