    摘要： An implantable cardiac stimulator has locking device for a pin-like conductor element of an electrode lead, the locking device having a helical coil which can assume a first, locking position, in which it grips the pin-like conductor element inserted into the coil to prevent longitudinal movement of pin-like conductor element, and a second, release position in which the pin-like conductor element is free to move in and out of the coil in relation to the coil's longitudinal axis. The first position is assumed when the coil is not influenced in its helix diameter increasing direction and the second position being assumed when the coil is influenced in its helix diameter increasing direction. The locking device also has a blocking component which only prevents the coil from rotating in the unwinding direction around its longitudinal axis in the locking device.

    摘要： The above objects are achieved in accordance with the principles of the present invention in a female connector part for cooperation with an elongated male connector part, the female connector part being intended for use in a pacemaker housing and having a longitudinal bore adapted to receive the male connector part. An element carrying resilient tongues, disposed at a small inward angle, i.e. inward from the opening of the female connector part, relative to a plane orthogonal to the longitudinal axis of the bore. The tongues are movable between a first position at which the respective tips of the tongues can engage the male connector part in the bore, and a second position at which the tips of the tongues do not engage the male connector part in the bore. The female connector part also includes a sleeve which is movable between two positions respectively corresponding to the first and second positions of the tongues. In a first position of the sleeve, the tongues are free to engage the male connector part in the bore, and in a second position of the sleeve, the sleeve is located between the tongues and the male connector part, thereby precluding the tongues from engaging the male connector part.

    摘要翻译： 根据本发明的原理，上述目的是在一个阴连接器部分中实现的，用于与细长的阳连接器部分配合，阴连接器部分用于起搏器壳体并具有适于接收阳极的纵向孔 连接器部分。 携带弹性舌片的元件相对于与孔的纵向轴线正交的平面以小内向角，即从阴连接器部分的开口向内设置。 舌片可以在第一位置和第二位置之间移动，在第一位置，舌头的各个尖端可以接合在孔中的阳连接器部分，舌片的尖端不与孔中的阳连接器部分接合的第二位置。 阴连接器部分还包括可在分别对应于舌头的第一和第二位置的两个位置之间移动的套筒。 在套筒的第一位置，舌状物可自由地与孔中的阳连接器部分接合，并且在套筒的第二位置中，套筒位于舌部和阳连接器部分之间，从而排除舌片接合 公连接器部分。
