摘要： A dilatation catheter is described wherein a plurality of oblong perfusion ports are provided in the catheter shaft to provide perfusion flow of blood through the distal section of the catheter. Oblong perfusion ports are preferably provided both proximal and distal to the inflatable dilatation balloon. Orienting the long dimensions of the oblong perfusion ports at an angle from the longitudinal axis of the catheter shaft minimizes kinking of the catheter shaft when passing through tortuous passageways.
摘要翻译：描述了一种扩张导管，其中在导管轴中提供多个长圆形灌注端口以提供血液通过导管的远端部分的灌注流动。优选地，可充气膨胀气囊的近端和远端都设置有长长的灌注口。将长方形灌注端口的长尺寸定向在与导管轴的纵向轴线成一定角度的位置，当通过曲折的通道时导致导管轴的扭结最小化。

摘要： A balloon dilatation catheter having means to raise the temperature of the working surface of the balloon while the balloon is being inflated during an angioplasty procedure. In one embodiment, the balloon is provided with a thin electrically conductive layer in heat transfer relationship therewith preferably on the interior surface of the balloon. Electrical power at radio frequencies is preferred and a coaxial cable is employed to deliver such power to a conductive layer for heating the balloon. In another embodiment, the balloon itself is formed of electrically conductive material. A perfusion lumen may be provided through the balloon with one or more proximal inlet ports and one or more distal discharge ports in fluid communication with the lumen to allow blood to pass through the balloon when it is inflated during angioplasty procedures. This facilitates the flow of oxygenated blood distally of the catheter when the balloon is inflated thus allowing for extended balloon inflations, e.g., up to 30 minutes or more.
摘要翻译：一种球囊扩张导管，其具有在血管成形术程序期间气囊膨胀时提高球囊工作表面的温度的装置。在一个实施例中，球囊设置有与传热关系的薄的导电层，优选地在球囊的内表面上。无线电频率下的电力是优选的，并且使用同轴电缆将这种功率传递到用于加热球囊的导电层。在另一个实施例中，球囊本身由导电材料形成。可以通过球囊提供灌注腔，其具有一个或多个近侧入口端口和一个或多个与内腔流体连通的远端排出口，以允许血液在血管成形术程序期间膨胀时通过气囊。当球囊膨胀时，这有助于导管的远端氧合血液的流动，从而允许延长气囊膨胀，例如长达30分钟或更长时间。
