摘要： The present teachings provide devices for puncturing the atrial septum percutaneously. Specifically, one aspect of the present teachings provides a trans-septal puncturing device comprising one or more of a locating element, a stabilizing element, a puncturing element, a safety element, and optionally a monitoring element, each of which is disposed in a lumen of a sheath. The locating element and the stabilizing element locate a desired puncture site and stabilize the trans-septal puncturing device at or near the site. The puncturing element of the trans-septal puncturing device has a limited puncturing distance due in certain instances to the safety element. The present teachings provide methods of using such device for percutaneously locating a fossa ovalis, stabilizing such device at the fossa ovalis, and piercing tissue across the fossa ovalis.

摘要： The present teachings provide a device to close a ductus arteriosus percutaneously. One aspect of the present teachings provides a device comprising at least one flange portion configured to be positioned against a vascular wall outside one end of a ductus arteriosus, and a body portion configured to be positioned inside the ductus arteriosus. The body portion of the device has a length adjustable in order for the device to fit inside patients with various ductus arteriosus lengths. The at least one flange portion of the device has pivotability in order for at least one flange to deflect from the longitudinal axis of the body portion so that the deployed device can be positioned at a treatment site allowing the discs to sit flat against the vascular tissue to promote closure while avoiding disruption of flow within the pulmonary artery and aorta or applying excess pressure to the surrounding vascular tissue. The body portion of the device could also at least partially block the ductus arteriosus, and thereby reduce or obstruct blood flow through the ductus arteriosus. The device includes a delivery profile and a deployment profile. Another aspect of the present teachings provides methods of using a device of the present teachings.
摘要翻译： 本教导提供经皮闭塞动脉导管未闭的装置。 本发明的一个方面提供了一种装置，其包括至少一个凸缘部分，该凸缘部分构造成抵靠动脉导管未闭的一端处的血管壁定位，以及构造成位于动脉导管内的主体部分。 装置的主体部分具有可调节的长度，以便装置适合于具有各种动脉导管未闭的长度的患者。 该装置的至少一个凸缘部分具有可枢转性，以使至少一个凸缘从主体部分的纵向轴线偏转，使得展开的装置可以定位在处理位置，从而允许圆盘平靠在血管组织上 以促进闭合，同时避免肺动脉和主动脉内的流动破裂或对周围血管组织施加过量压力。 装置的主体部分还可以至少部分地阻塞动脉导管，从而减少或阻碍通过动脉导管的血流。 该设备包括传送配置文件和部署配置文件。 本教导的另一方面提供使用本教导的装置的方法。
