    摘要： A deflection mechanism for selectively inducing a bend in a catheter body includes an elongated deflection wire extending within a deflection lumen of the catheter body and into a handle. A guide track is formed within the handle and a thumb wheel is mounted proximal to the elongated guide track within the handle and supports a pinion gear; the thumb wheel and the pinion gear are adapted to be rotated about a common thumb wheel axis, which extends substantially perpendicular to the longitudinal axis. A rack arm extends obliquely to the longitudinal axis of the handle and includes runners received by the guide track, an attachment point coupling the deflection wire to the rack arm and a linear rack engaging the pinion gear. Rotation of the thumb wheel in a first direction draws the deflection wire proximally through the deflection lumen.

    摘要翻译： 用于选择性地诱导导管主体中的弯曲的偏转机构包括在导管主体的偏转腔内延伸并延伸到手柄中的细长偏转线。 引导轨道形成在手柄内，拇指轮安装在手柄内的细长导轨附近，并支撑小齿轮; 拇指轮和小齿轮适于围绕基本上垂直于纵向轴线延伸的公共拇指轮轴旋转。 齿条臂相对于手柄的纵向轴线倾斜地延伸，并且包括由导轨接收的跑道，将偏转线连接到齿条臂的连接点和与小齿轮啮合的直线齿条。 拇指轮在第一方向的旋转将偏转线向近侧拉出通过偏转内腔。

    摘要： A trans-septal guide catheter for providing access through the septum separating a first heart chamber from a second heart chamber that includes an elongated guide catheter body extending between guide catheter proximal and distal ends. A distal segment of the guide catheter is adapted to be inserted through the septum to locate the distal segment of the guide catheter within one of the first heart chamber and the second heart chamber. The catheter body encloses a guide catheter lumen adapted to provide access into the one of the first heart chamber and the second heart chamber through a guide catheter lumen proximal end opening and a guide catheter lumen distal end opening. A retention mechanism engages the septum and maintains the distal segment of the guide catheter extending into the one of the first heart chamber and the second heart chamber.
