    • A plurality of embodiments of a distal perfusion device are disclosed, which device facilitates anastomosis constructions by maintaining a dry anastomosis site while simultaneously maintaining blood flow distally in the blood vessel to prevent ischemia and reduce overall patient trauma. The perfusion device is configured for installation into a blood vessel such as a left anterior descending coronary artery through an incision therein, to which is to be grafted a distal end of a blood vessel such as an internal mammary artery. The device includes a central member of selected configuration and material, terminating at either end thereof in respective selectively tapered end members. A lumen extending through the central member and end members, and selected perforations in the end members, maintain blood flow through the perfusion device. A selected portion or portions of the device's outer circumference fit snugly within the artery in the regions beyond and/or at the anastomosis site, to maintain the latter free of blood. Several methods for deploying and removing respective embodiments of the device also are illustrated.
    • 公开了一种远端灌注装置的多个实施例,该装置通过维持干吻合部位来促进吻合结构,同时在血管中保持血液向远端流动以防止局部缺血并减少总的患者创伤。 灌注装置被构造成通过其中的切口安装到诸如左前降支冠状动脉的血管中,其将被移植到诸如内部乳腺动脉的血管的远端。 该装置包括选定构型和材料的中心构件,其终端位于相应的选择性锥形端构件的任一端。 延伸穿过中心构件和端构件的内腔以及端构件中选择的穿孔保持血流通过灌注装置。 装置的外周的选定部分或部分适合紧贴在吻合部位之外和/或处于吻合部位的区域内的动脉内,以保持后者无血液。 还示出了用于部署和移除设备的各个实施例的几种方法。

    • 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.
    • 公开了一种低调的不引人注意的闭塞器装置,其特别适用于在微创搏动心脏CABG外科手术中闭塞血管,其中提供了相对较小的手术开口。 至少一个柔性构件设置在封闭器上,其抵靠容器放置。 缝合线在血管下方通过封闭器和缝合线之间的容器。 缝合线选择性地附接到闭塞器,使得当变形时,柔性构件在缝合线上施加连续的选定张力,以在封闭血流的血管上施加相应的压缩。 敷贴器附接到封堵器以使其能够安装,但是在安装之后可拆卸,使得在外科手术期间只有低轮廓的封堵器保留在心脏表面上。 将施用器重新连接到封堵器以便于去除封堵器。 在替代实施例中,封堵器形成为开胸稳定器装置的心脏接触构件的可调部分。

    • 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.
    • 本发明是使用通过外科器械施加的负(吸力)压力或真空来固定跳动心脏表面的一部分的位置使得外科手术可以更容易地进行的装置和技术。 这些装置在心脏的外表面上的几个点处施加负压,使得心脏的一部分通过通过手术器械施加的抽吸被固定就位。 因为仪器固定组织的位置,并且因为仪器保持与正在执行手术的心脏的特定部分恒定的距离,所以该装置还可以用作支撑或平台,使得其它手术器械或装置 可以有利地在现场使用。 在某些优选实施例中,本文所述的装置具有便于使用额外外科器械的结构,使得负压装置的放置允许外科医生在手术期间有利地操纵其他器械。 负压优选通过多个端口施加,所述多个端口可以设置在与心脏组织接触的仪器的基本平坦的表面中。
