摘要： The emboli protection system provides one or more inflatable blocking balloons for isolation of a section of a blood vessel to prevent migration of emboli from the section during an interventional procedure, and fluid infusion and evacuation ports for flushing emboli from the isolated section. One embodiment provides for a distal blocking balloon catheter, over which an interventional device can be introduced, and a proximal blocking balloon catheter to be introduced over the interventional device for isolating a portion of a blood vessel to be treated. The blocking balloons can be perforated to provide the infusion ports, and thrombolytic inflation fluid may be used to break down and dissolve thrombus and plaque in the isolated portion of the blood vessel. The interventional therapeutic device such as an angioplasty balloon catheter may be incorporated into the distal blocking balloon catheter, or the distal and blocking proximal balloon catheters can be incorporated with the interventional therapeutic device together in one device. Infusion ports may also be provided in either or both of the distal and proximal blocking catheters.

摘要： A pin pulling and inserting block has a channel therein in the shape of a rectangular parallelepiped which opens on one end of the block and is large enough to admit the head of a retaining pin on an integrated circuit package shipping rail. There is a tapered ramp within the channel which progressively narrows the depth of the channel from a dimension which is larger than the depth of the pinhead to a dimension that will snugly hold the pinhead. A slot extends through the block from the channel opening and opens into the channel. The slot is wide enough to admit the shank of a pin whose head is admitted into the channel. There is a rounded surface on the end of the block opposite the channel opening which acts as a fulcrum for prying the pin out of the shipping rail. The pin remains snugly held in the channel after it is removed from the rail and can be easily inserted back into the rail by simply pressing the rail against the exposed end of the pin.

摘要翻译： 销拉和插入块在其中具有长方体形状的通道，该通道在块的一端开口，并且足够大以允许固定销的头部承载在集成电路封装运输轨道上。 在通道内有一个锥形斜坡，其逐渐将通道的深度从大于针头深度的尺寸缩小到将紧密地保持针头的尺寸。 槽从通道开口延伸穿过块并且通向通道。 狭槽足够宽以允许其头部进入通道的销的柄。 在与通道开口相对的块的端部上具有圆形表面，其作为用于将销从运输轨道撬出的支点。 在将导轨从导轨上取下后，销保持牢固地保持在通道中，并且可以通过简单地将导轨压靠在销的暴露端而容易地插入轨道。
