US Patent 10252032 Socketed portal anchors and methods of using same

Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.
