Abstract: A burr hole cover includes a cap or cap assembly and a retainer and is configured to be partially positioned within a burr hole formed in a patient. The retainer has a cap-receiving aperture; a plurality of grooves provided in the retainer and a plurality of cut-outs wherein each cut-out is provided at an end of each groove towards the outer perimeter of the retainer. A channel may be provided at an opposite end of each groove vertically-extending from the top to the bottom of the retainer to encourage a medical device segment to remain in a groove during installation of the burr hole cover. The burr hole cover may be used to secure segments of medical devices relative to a burr hole and to allow a range of lateral motion for the portion(s) of the medical device(s) extending proximally out of the corresponding groove.

Abstract: A burr hole cover is configured to be recessed in a burr hole formed in a patient and includes a base and a cap provided with complementary features to allow a portion of a medical device, such as a brain lead, to be situated in the burr hole cover and then secured by rotation of the cap relative to the base. The features include channels on the base and matching cut-outs on the cap, and slots and locking pockets on the base that are configured to be aligned with locking tabs and locking protrusions on the cap. Because the burr hole cover is recessed in the burr hole, the medical device can extend proximally of the burr hole at the level of the cranium. A bottom surface of the cap may be provided with guides for the lead extending distally in towards the brain.
Abstract translation: 毛刺孔盖被构造成凹陷在形成于患者体内的毛刺孔中，并且包括基部和具有互补特征的帽，以允许诸如脑引线的医疗装置的一部分位于钻孔中 盖，然后通过帽相对于底座的旋转来固定。 这些特征包括基座上的通道和盖上的匹配切口，以及基座上的槽和锁定凹槽，其配置成与锁定突起对准并且在盖上锁定突起。 由于毛刺孔盖凹陷在毛刺孔中，所以医疗装置能够在颅骨水平面上的毛刺孔的近侧延伸。 盖的底表面可以设置有用于朝向脑部向远侧延伸的引线。

Abstract: A lead fixation device for securing a first portion of a lead relative to a hole formed through a skull includes a skull attachment member having an upper surface and a lower surface and a bore extending through and between the upper surface and the lower surface. The lead fixation device also includes a lead compression mechanism integral with the skull attachment member and aligned with the bore of the skull attachment member. The lead compression mechanism defines a passageway through the lead fixation device, which passageway is characterized by a diameter that is defined by the lead compression mechanism. The lead compression mechanism is configured to transition the diameter from a first size to a second size greater than the first size upon insertion of an implant tool through the passageway, and from the second size to the first size upon removal of the implant tool from the passageway.

Abstract: A lead fixation device for securing a portion of a lead relative to a surface of a skull includes a skull attachment member having an upper surface and a lower surface, a locking member having an upper surface and a lower surface and associated with the skull attachment member, and a passageway associated with the locking member and configured to receive the portion of the lead. The skull attachment member and the locking member are configured to rotate relative to each other to transition the lead fixation device between a closed state wherein the lower surface of the skull attachment member and the lower surface of the locking member are generally aligned in a common plane, and an opened state wherein the lower surface of the skull attachment member and the lower surface of the locking member are not aligned in a common plane.
