摘要： A catheter for removing tissue from a body lumen includes a rotatable cutter. The cutter includes an annular cutting edge at the distal end portion of the cutter for removing tissue from the body lumen. An axial cavity is defined by an interior surface of the cutter and extends proximally from the annular cutting edge toward the proximal end portion of the cutter. An eccentric opening extends from the central cavity through the cutter to allow tissue removed from the body lumen by the annular cutting edge to pass proximally through the eccentric opening toward an interior passage of the catheter body. The offset opening is offset from the longitudinal axis of the cutter.

摘要： Systems, devices, and methods for removing plaque from a patient's vasculature. In one example, a medical article includes a catheter body and a dissection tip. The dissection tip can move between at least a first position and a second position and can be biased to expand radially from a longitudinal axis of the medical article when the dissection tip is moved from the first position to the second position. In one example, a dissection member includes a dissection tip and a receiving space. The dissection tip can radially adjust to circumferentially maneuver between a core of plaque and a patient's vasculature. The receiving space can receive at least a portion of a core of plaque that passes through the dissection tip.

摘要： A discrete segmented balloon catheter for removal of an embolus. In an embodiment, the catheter comprises a catheter having a proximal and a distal end, a fluid inlet at the proximal end, and discrete expandable segments placed along the shaft of the catheter. In addition, the segments are expanded through dispersal of fluid that flows from the catheter's proximal inlet. It follows that the segments are contracted through withdrawal of fluid from the catheter's proximal inlet.

摘要： A device for folding a balloon of a balloon catheter onto a catheter tube during a balloon deflation includes a first band positioned on the catheter tube distal to the balloon and a second band positioned on the catheter tube proximal to the balloon. One or more elastic member(s) are attached to and extend between the bands for interaction with the outer surface of the balloon. During a balloon deflation, the elastic members cooperate to fold the balloon into pleats. When used on a cutting balloon, each elastic member is formed with a slot to allow a respective blade of the cutting balloon to extend through the elastic member. The elastic members fold the cutting balloon into a configuration in which each blade becomes nestled within a pair of adjacent balloon pleats to prevent the blade from inadvertently incising tissue during an in-vivo movement of the balloon catheter.
摘要翻译：用于在球囊放气期间将球囊导管的球囊折叠到导管上的装置包括位于远离球囊的导管管上的第一带和位于靠近球囊的导管上的第二带。一个或多个弹性构件附接到带之间并且在带之间延伸以与球囊的外表面相互作用。在气球放气期间，弹性构件协作以将气球折叠成褶皱。当在切割气球上使用时，每个弹性构件形成有狭槽，以允许切割气囊的相应刀片延伸穿过弹性构件。弹性构件将切割气球折叠成其中每个叶片变得嵌套在一对相邻气囊褶皱内的构造，以防止在球囊导管的体内运动期间叶片无意中切开组织。
