    Abstract: A tine portion of an implantable medical device includes a hook segment and a distal segment extending therefrom, wherein the hook segment is pre-set to extend along a curvature and is elastically deformable therefrom to an open position. The distal segment includes a tooth and an end that surrounds the tooth, wherein the end includes a pair of legs and a distal arch. The legs extend along a length of, and on opposing sides of the tooth, and the distal arch extends between the legs, distal to a tissue-piercing tip of the tooth. When the hook segment is in the open position, and a force is applied along a longitudinal axis of the device, to push the distal arch of the distal segment against tissue, for initial tissue penetration, the legs of the end of the distal segment bend in elastic deformation to expose the tissue-piercing tip to the tissue.

    Abstract: A tine portion for an implantable medical device includes a hook segment and a distal segment terminated by a tissue-piercing tip, wherein the distal segment extends from the hook segment to the tip. The hook segment, which is elastically deformable from a pre-set curvature, has one of: a round cross-section and an elliptical cross-section, while the distal segment has a flattened, or approximately rectangular cross-section. One or a pair of the tine portions may be integrally formed, with a base portion, from a superelastic wire, wherein the base portion is configured to fixedly attach to the device, for example, being captured between insulative members of a fixation subassembly.

    Abstract translation: 用于可植入医疗装置的牙齿部分包括钩部分和由组织穿刺尖端终止的远侧部分，其中远端部分从钩部分延伸到尖端。 从预设的曲率可弹性变形的钩段具有圆形横截面和椭圆形横截面，而远端段具有扁平或近似矩形的横截面。 一个或一对齿部可与来自超弹性线的基部一体地形成，其中基部被构造成固定地附接到装置，例如被捕获在固定子组件的绝缘构件之间。
