    • 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。

    • An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system on a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allow some manipulation of the guidewire independently of the filter when the filter is in use.
