摘要： A lead having an extendable and retractable fixation mechanism (120) has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin (310) is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring (150) disposed at the distal end of the lead provides information during the implantation process.

摘要： A single-pass endocardial lead electrode for implantation within a single chamber of the heart, or multiple chambers of the heart. The lead includes a first distal end electrode and a second electrode. The first and second electrodes are either passively or actively attached to the wall of the heart. The lead body also includes a curved portion which facilitates the positioning of the second electrode. The main lead body alternatively includes a recess into which an atrial lead body and an active fixation element attached to one end can travel from a recessed position to a position for fixation to the wall of the heart. The active fixation element can also be moved by turning the terminal pin. The lead body can also include multiple legs, each leg carrying an electrode. The lead is attached to a pulse generator for producing pulses to the multiple sites within the heart. A movement assembly for advancing a helix is also included within the legs and comprises an externally threaded collar which engages with an internally threaded housing or housing insert. The lead further includes a helical tip which has high impedance.
摘要翻译：用于植入心脏的单个腔室或心脏的多个腔室内的单程心内膜导联电极。引线包括第一远端电极和第二电极。第一和第二电极被动地或主动地附着在心脏的壁上。引线体还包括便于第二电极定位的弯曲部分。主引线主体备选地包括凹部，心房导线主体和附接到一端的主动固定元件可以从凹入位置行进到用于固定到心脏壁的位置。主动固定元件也可以通过转动端子销来移动。引线体还可以包括多个腿，每个腿携带电极。导联连接到脉冲发生器，用于向心脏内的多个部位产生脉冲。用于推进螺旋的运动组件也包括在支腿内并且包括外螺纹套环，该外螺纹套环与内螺纹外壳或外壳插入件接合。引线还包括具有高阻抗的螺旋尖端。
