可植入医疗装置的固定
摘要：
一种组件包括可植入医疗装置（IMD）和附连至IMD的固定件组件，该可植入医疗装置包括导电外壳。固定件组件包括一组主动固定叉形件和将该组主动固定叉形件与可植入医疗装置的导电外壳电绝缘的绝缘体。该组中的主动固定叉形件可从其中主动固定叉形件的背离可植入医疗装置指向的远端的弹簧加载位置展开至其中主动固定叉形件朝向可植入医疗装置后弯的钩住位置。主动固定叉形件构造成当展开时，将可植入医疗装置固定至患者组织，同时主动固定叉形件的远端相邻于患者组织定位。
摘要（英）：

An implantable medical device comprising a housing, a set of active fixation tines (103) attached to a distal end (114) of the housing, the fixation tines each having a proximal end attached to the distal end of the housing, and a free distal end for engaging tissue; wherein the fixation tines are configured to be moveable between an extended position in which the free distal ends of the tines are distal of the distal end of the housing, and an engaged position in which the free distal ends of the tines are proximal of the distal end of the housing.
