    摘要: The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing device, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing device such that the contraction of the beating heart causes only minimal excess motion at the surgery site. By fixing the position of the stabilizing device in a configuration where the motion of the beating heart is effectively eliminated, the surgeon is able to stabilize the beating heart for the duration of the procedure. The stabilizing device may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention. In certain preferred embodiments, the stabilizing device is affixed to a semi-rigid support which is caused to become rigid, by any of a variety of techniques, such that the position of the stabilizing device becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.

    摘要: A cannula for draining blood from a patient's heart during cardiac surgery including a main body and a pair of branches extending distally therefrom. The branches are biased to extend away from one another by pre-shaped stiffening elements, and have "D" shaped cross-sections defining flat surfaces oriented generally towards one another. The branches may be constrained in a retracted position, the flat surfaces abutting one another, and the resulting profile forming a substantially continuous extension of the main body. The branches have distal tips including drainage holes and occlusion balloons, and elbow portions including accordion-like ridges for preventing kinking. Grooves in the flat surfaces define a secondary lumen in the retracted position through which a cardioplegia delivery or an imaging device may be advanced. The cannula is directed into a trocar to constrain the branches in the retracted position, and the trocar is inserted into the right atrium. The trocar is withdrawn to deploy the branches, which automatically extend away from one another, assuming a tripartite configuration wherein the branches extend substantially transversely from the main body, and enter the superior and inferior vena cavae. The occlusion balloons are inflated to isolate the vena cavae and blood is drained therefrom for delivery to a pump-oxygenator. A cardioplegia delivery device is advanced through the secondary lumen into the coronary sinus, an occlusion balloon on a distal tip of the device is inflated to isolate the coronary sinus, and retrograde delivery of cardioplegia is achieved.

    摘要: Devices and methods for minimally invasive harvesting of a vessel, especially the saphenous vein for coronary artery bypass grafting, are disclosed which facilitate a minimally invasive vessel harvesting procedure. Generally, an instrument is provided which facilitates introduction of vessel harvesting tools through a minimally invasive incision, and provides the capability to separate the vessel from surrounding tissue while minimizing trauma to the patient and preserving the patency of the vessel. The instrument includes a mechanism for separating the vessel from surrounding tissue and may also include mechanisms for severing side branches from the vessel during the harvesting procedure. In one embodiment, an integrated vessel harvesting assembly is provided which may rotate around a vessel and provides a unitary mechanism for separating the vessel from surrounding tissue and for severing the side branches.

    摘要: A low profile unobtrusive occluder device is disclosed which is particularly applicable for occluding blood vessels in minimally invasive beating heart CABG surgical procedures, wherein relatively small surgical openings are provided. At least one flexible member is provided on the occluder, which is placed against the vessel. A suture thread is passed under the vessel to encompass the vessel between the occluder and suture thread. The suture thread is selectively attached to the occluder such that the flexible member, when deformed, applies continuous selected tension on the suture thread to apply a corresponding compression on the vessel which occludes the flow of blood. An applicator is attached to the occluder to enable installation thereof, but is detachable after installation such that only the low profile occluder remains on the heart surface during surgery. The applicator is re-attached to the occluder to facilitate removal of the latter. In an alternative embodiment, the occluder is formed as an adjustable part of a heart contacting member of a thoracotomy stabilizer apparatus.
