摘要： A transseptal needle includes an elongate needle body having a distal end and a proximal end and a cannular needle tip located proximate the distal end of the needle body. The needle tip has a distal segment, a proximal segment, and a longitudinal axis. An inner surface of the needle tip defines a passageway spanning at least a portion of the needle tip, and an outer surface of the needle tip defines a wall with the inner surface. The distal segment of the needle tip also includes a wedge surface and a dome-shaped region. The wedge surface forms a wedge angle of other than 90 degrees relative to the longitudinal axis. The dome-shaped region, which intersects the wedge surface, includes at least two bevels that intersect the wedge surface and that intersect each other at one or more points on the needle tip.
摘要翻译：经导管针包括具有远端和近端的细长针体和位于针体远端附近的管状针尖。针尖具有远侧段，近端段和纵向轴线。针尖的内表面限定跨过针尖的至少一部分的通道，并且针尖的外表面限定具有内表面的壁。针尖的远端部分还包括楔形表面和圆顶形区域。楔形表面相对于纵向轴线形成不同于90度的楔角。与楔形表面相交的圆顶形区域包括与楔形表面相交并且在针尖上的一个或多个点处彼此相交的至少两个斜面。

摘要： The instant invention is directed toward transseptal puncture needles and transseptal puncture needle assemblies. More specifically, it relates to curved transseptal puncture needles and needle assemblies that facilitate insertion through curved transseptal introducers. Each curved transseptal puncture needle includes a needle tip with a tangential back bevel configuration, a reverse tangential back bevel configuration, or a conical reverse bevel configuration. The axial orientation of the needle tip relative to the needle curvature, whether on the concave side or convex side of the curved transseptal puncture needle, provides additional benefits. The leading edge of the needle tip is located at a distal end of an inner needle tube, and the leading edge of the needle tip may be positioned away from an outer surface of the inner needle tube and adjacent to an inner surface of the inner needle tube.
摘要翻译：本发明针对经血穿刺针和经血管穿刺针组件。更具体地说，它涉及弯曲的经外穿刺针和针组件，其有利于通过弯曲的经皮导入器插入。每个弯曲的经外穿刺针包括具有切向后斜面构造的针尖，反向切向后斜面构型或锥形倒角构造。针尖相对于针曲率的轴向方向，无论是在弯曲的经外穿刺针的凹侧或凸侧，都提供了额外的好处。针尖的前缘位于内针管的前端，针尖的前缘可以远离内针管的外表面并且靠近内针的内表面管。

摘要： Disclose herein is a method of measuring pressures in a coronary sinus. In one embodiment, the method includes: introducing a distal portion of a lead or tool into the coronary sinus, wherein the distal portion includes first and second pressure sensors and at least one selectably expandable member; expanding the at least one expandable member such that the first and second sensors are isolated from each other within the coronary sinus; and taking pressure measurements with the first and second sensors when isolated from each other.
