摘要： A tissue penetrating fixation component for an implantable medical device, the component comprising a base portion (603) and at least one tine portion (630), the base portion defining a longitudinal axis and being configured to be fixedly attached to the medical device such that the longitudinal axis extends approximately parallel to a longitudinal axis of the device. The tine portion comprises a hook segment (631) and a distal segment (632) terminated by a tissue-piercing tip (622). The hook segment is pre-set to extend along a pre-set curvature that encloses an angle of between 135 degrees and 270 degrees, from a proximal end thereof, in proximity to the base portion, to a distal end thereof, and is elastically deformable from the pre-set curvature to an open position. The distal segment is pre-set to extend along a relatively straight line that is approximately tangent to the distal end of the hook segment, from the distal end of the hook segment to the tip. The hook segment (631) tapers from a first width (W1) thereof, in proximity to the proximal end thereof, to a smaller second width (W2) thereof, in proximity to the distal end thereof, and the tissue-piercing tip (622) of the tine portion has a width (W3) that is greater than the second width (W2) of the hook segment.

摘要： 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.
摘要翻译：可植入医疗装置的尖端部分包括钩部分和由组织刺穿尖端终止的远端部分，其中远端部分从钩部分的远端延伸到尖端。例如由单个半径限定的可从预先设定的曲率弹性变形的钩部段优选地从其近端附近的第一宽度逐渐变窄到其较小的第二宽度到达其远端，其中尖端的宽度大于钩部分的第二宽度。可选地，齿部分可以包括由两个半径限定的钩部分和在其间延伸的直线部分。
