Abstract: A fixation member component, for example, employed by a relatively compact implantable medical device, includes a plurality of fingers; each finger includes a first segment extending from a fixed end of the corresponding finger, and a second segment extending from the corresponding first segment to a free end of the corresponding finger. Each first segment is elastically deformable from a relaxed to an extended condition, and from the relaxed to a compressed condition, and includes a peripheral portion and a central cut-out portion, framed by the peripheral portion. In the compressed condition, a free tip of the cut-out portion of some or all of the fingers may lodge against opposing tissue surfaces, via a spring force of the compressed fingers. Each second segment and cut-out portion is preferably configured to prevent penetration thereof within tissue at the implant site.
Abstract translation: 例如由相对紧凑的可植入医疗装置使用的固定构件部件包括多个手指; 每个手指包括从相应手指的固定端延伸的第一段和从对应的第一段延伸到相应手指的自由端的第二段。 每个第一段可从松弛到伸长状态弹性变形，并且从松弛到可压缩状态，并且包括由周边部分构成的周边部分和中央切口部分。 在压缩状态下，部分或全部手指的切口部分的自由尖端经由压缩手指的弹簧力抵靠在相对的组织表面上。 每个第二段和切口部分优选地构造成防止在植入部位的组织内的穿透。

Abstract: A tine portion of an implantable medical device includes a hook segment and a distal segment terminated by a tissue-piercing tip, wherein the distal segment extends from a distal end of the hook segment to the tip. The hook segment, which is elastically deformable from a pre-set curvature, for example, defined by a single radius, preferably tapers from a first width thereof, in proximity to a proximal end thereof, to a smaller, second width thereof, in proximity to the distal end thereof, wherein the tip has a width that is greater than the second width of the hook segment. Alternately, the tine portion may include a hook segment that is defined by two radii and a straight section extending therebetween.
