    摘要: A device for occlusion of a body passageway and subsequent perfusion of the body passageway with arterial return blood, cardioplegia and other fluid is disclosed. The device of the present invention is an expandable cannula comprising a flexible, expandable tubular elongate body having a first diameter and a second diameter, wherein the expandable cannula is inserted having a first diameter and then expanded to a second diameter to provide perfusion flow to the body passageway through at least one arterial return aperture provided on the distal end of the expandable tubular elongate body in fluid communication with a perfusion lumen provided within the cannula. The device may be further provided with one or more additional lumens for providing additional functions to the vessel lumen and may also include an expandable occluding member fixed at the distal end of the cannula for isolating the surgical area from the rest of the arterial system. A preferred method of use of the present invention is also disclosed wherein having a first diameter is inserted endovascularly into the vessel of a patient and advanced to a point of interest. At the point of interest, the device is expanded to a second diameter and perfusion flow to the vessel lumen is provided. Following the performance of a surgical procedure, perfusion flow is terminated and the device is removed from the vessel.

    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.

    摘要: Several embodiments of a clamping device are disclosed, for tightening and securing a purse string suture used to seal the tissue around a cannula or a catheter or the like placed in a heart, major vessel or other tissue structure. The clamping device includes a compressible sleeve means solidly secured at a proximal end to a compression-applying means such as a clamp mechanism. A suture-pulling needle is inserted through a common lumen, whereby the trailing ends of the suture thread which forms the purse string suture may be pulled through the compressible sleeve means and clamp mechanism. Application of a force to the clamp mechanism while it is not locked to the trailing ends compresses the compressible sleeve means. Release of the clamp mechanism locks the enclosed trailing ends of the suture thread. The compressed sleeve means applies constant and precalibrated tension on the purse string suture to continuously maintain the seal about the cannula. The clamping device is removed by unlocking the clamp mechanism and withdrawing the device from the suture thread.

    摘要: An automatic purse string suture device is disclosed that enables a surgeon to install a purse string suture in tissue structures, particularly for sealing the tissue about a cannula. The device is particularly suited for minimally invasive cardiothoracic procedures and is comprised of an applicator having an elongated structure with protrusions extending from the distal edge thereof. Also provided are means for advancing a needle through a passage to pass a suture through tissue that has been conformed to the distal edge of the device. Various means for conforming the tissue to the distal edge are disclosed as are methods for using the device to facilitate cardiothoracic surgery.

    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.
