Title
(EN) Methods for self-centering a guide catheter
(ZH) 用于使引导导管自对中的装置
Abstract
(EN)
A guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, for treatment of heart conditions such as valvular stenosis. For example, a guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, or any other normal or abnormal passage in the body against the direction flow. This device can also be used to localize and repair leaks where a fluid flow jet is present in submerged or fluid-filled chambers. A device for centering a medical instrument in a body conduit includes a framework of frame members, defining a lumen with open ends; and a covering.

引导导管能将自身与血液流对准,由此有助于将从引导导管传递出的引导线或其他细长装置引导穿过心脏瓣口,以治疗诸如瓣膜狭窄之类心脏状况。例如,引导导管能将自身与血液流对准,由此有助于将从引导导管传递出的引导线或其他细长装置与方向流相逆地引导穿过心脏瓣口或者身体中任何其他正常或异常通道。该装置也可用于定位并修复在浸没的或流体填充的腔室中存在流体射流的位置处的泄露。一种用于使医疗仪器在身体导管中对中的装置包括:由多个框架部件制成的构架,其限定具有多个开口端的内腔;和覆盖件。
