阅读说明：本技术 组织移除导管 (tissue removal catheter ) 是由 A·詹莫斯 J·凯利 C·麦克马伦 M·弗莱明 C·米德 G·卡罗尔 于 2018-05-03 设计创作，主要内容包括：一种用于移除体腔中的组织的组织移除导管(10)包括细长主体(12),该细长主体的尺寸和形状设计成接纳在体腔中。手柄(40)安装在导管(10)的近端部分处并且可操作以使得细长主体(12)的旋转。组织移除元件(20)安装在细长主体(12)的远端部分上。组织移除元件(20)构造成随着该组织移除元件(20)在体腔内由细长主体(12)旋转而移除组织。导丝内腔(24)从导管(10)的远端延伸穿过细长主体(12)至导管(10)上的中间位置,该中间位置与导管(10)的近端部分向远侧间隔开。导丝内腔构造成接纳导丝(26),使得可以在不从体腔中移除导丝(26)的情况下通过沿着导丝(26)牵拉导管(10)来将导管(10)从体腔中移除。(a tissue-removing catheter (10) for removing tissue in a body lumen includes an elongate body (12) sized and shaped to be received in a body lumen. A handle (40) is mounted at a proximal end portion of the catheter (10) and is operable to cause rotation of the elongate body (12). A tissue-removing element (20) is mounted on a distal portion of the elongate body (12). The tissue-removing element (20) is configured to remove tissue as the tissue-removing element (20) is rotated within the body lumen by the elongate body (12). A guidewire lumen (24) extends through the elongate body (12) from the distal end of the catheter (10) to an intermediate location on the catheter (10) that is spaced distally from the proximal portion of the catheter (10). The guidewire lumen is configured to receive a guidewire (26) such that the catheter (10) can be removed from the body lumen by pulling the catheter (10) along the guidewire (26) without removing the guidewire (26) from the body lumen.)
