    • A one-piece electrical contact ring for use in a lead receptacle of an implantable medical device includes (i) a tubular body defining a cavity extending through the body and (ii) a plurality of resiliently deflectable elements extending from the tubular body into the cavity. The deflectable elements have a lead contacting portion configured to contact the lead when received by the cavity. The lead contacting portions of the deflectable elements in a relaxed state are located in a plane that intersects the tubular body and are configured to deflect along the plane towards the tubular body as the lead is inserted in the contact ring. The contact ring may further include a plurality of stops, each configured to (i) engage a stop portion of the elements when the elements are sufficiently outwardly deflected and (ii) inhibit further outward deflection of the elements when the stops engage the stop portions.
    • 用于可植入医疗装置的引线插座中的一体式电接触环包括(i)限定延伸穿过本体的空腔的管状体,和(ii)从管状体延伸到腔体中的多个可弹性偏转的元件 。 所述可偏转元件具有引线接触部分,所述引线接触部分构造成当由所述空腔接收时接触所述引线。 处于松弛状态的可偏转元件的引线接触部分位于与管状体相交的平面中,并且构造成当引线插入接触环时沿着平面朝向管状体偏转。 所述接触环还可以包括多个止动件,每个止动件构造成(i)当所述元件被足够向外偏转时,(i)接合所述元件的止动部分,以及(ii)当所述止动件接合所述止动部分时,阻止所述元件进一步向外偏转。
