Zusammenfassung:Suction medical devices, and methods for making and using suction medical devices, are disclosed. An example aspiration medical device may include a catheter shaft (116) having a distal end region and defining an inflow aperture adjacent the distal end region. A suction member (130) may be disposed within the catheter shaft. The suction member may have a plurality of axially spaced apart fluid ejectors (138) formed therein. A collar (340) may be disposed over the suction member (130). The collar (340) may have an injection support region (344) disposed adjacent to the at least one fluid injector and a wall support region disposed adjacent to a wall of the conduit shaft. 本发明公开了抽吸医疗装置、以及用于制造和使用抽吸医疗装置的方法。示例抽吸医疗装置可包括具有远端区域并限定邻近远端区域的流入孔口的导管轴(116)。抽吸构件(130)可设置在导管轴内。抽吸构件可具有形成于其中的多个轴向间隔开的流体喷射器(138)。套环(340)可设置在抽吸构件(130)之上。套环(340)可具有邻近至少一个流体喷射器设置的喷射支撑区域(344)和邻近导管轴的壁设置的壁支撑区域。
