    摘要: The invention is devices and techniques which use a negative (suction) pressure or vacuum, applied through a surgical instrument, to fix the position of a portion of the surface of a beating heart so that a surgical procedure can be more easily performed. The devices apply a negative pressure at several points on the outer surface of the heart such that a portion of the heart is fixed in place by the suction imposed through the surgical instrument. Because the instrument fixes the position of the tissue, and because the instruments remain at a constant distance from the particular portion of the heart where the surgery is being performed, the device may also serve as a support or platform so that other surgical instruments or devices can be advantageously used at the site. In certain preferred embodiments, the devices described herein have structures to facilitate the use of additional surgical instruments such that the placement of negative pressure device permit the surgeon to advantageously manipulate the other instruments during surgery. The negative pressure is preferably imposed through a plurality of ports which may be disposed in a substantially planar surface of the instrument which contacts the cardiac tissue.

    摘要: Methods and devices for revascularization of a patient's coronary artery system which obviate the need to place the patient on cardiopulmonary bypass. A method is provided for revascularizing a patient while the-heart is beating, and includes performing at least one minimally invasive coronary artery bypass graft procedure, or other cardiac surgical procedure, and contemporaneously performing at least one catheter-based procedure in at least one coronary artery. The catheter-based procedure(s) may be either therapeutic or diagnostic or both, and may involve delivering at least one catheter to a coronary artery via a surgical or percutaneous opening in the thoracic cavity or via a percutaneous opening at a location peripheral to the thoracic cavity. The catheter-based procedure or procedures is performed contemporaneously with the bypass graft procedure, and specifically prior to, during, or after anesthetizing the patient for purposes of the bypass graft procedure. An arterial access device is also provided for central cannulation and direct intraoperative catheterization of a patient's coronary artery system on a beating heart. The device includes a tubular member, such as a cannula, having a proximal end and a distal end, and an elongated puncturing member, such as a trocar, which is slideably disposed within the tubular member. The puncturing member has a sharp distal end for puncturing through the wall of a coronary lumen. The arterial access device further includes a sealing member for engaging the coronary lumen wall at the puncture site in order to minimize the leakage of blood from the puncture site.

    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 means, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing means such that the contraction of the beating heart causes only minimal excess motion at the surgery site. By fixing the position of the stabilizing means 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 means 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 means 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 means becomes fixed by the support, and the heart remains substantially motionless for the duration of the procedure.

    摘要: Surgical procedures on the beating heart are enabled by an incision made in the xyphoid area and specially designed retractors and related devices to facilitate cardiac surgical procedures. Specifically, coronary artery bypass graft procedures (CABG) are achieved using a vertically offsetting retractor or access platform in combination with a beating heart stabilizer. The surgical methodology permits procedures such as the CABG procedure without penetrating the rib cage or performing a sternotomy or thorocotomy.
