Claim Text:
1. An anchor configured to secure a medical device implanted via a portal formed in a mammalian body, the anchor comprising: a base operable to secure to tissue surrounding the portal, the base comprising an upper side, lower side, outer edge, and inner edge, the inner edge defining an opening passing between the upper and lower sides of the base, the opening forming a socket; and a retention member configured to be received within the socket and recessed into the portal, the retention member defining a bore configured to permit passage with clearance of the medical device through the retention member when the retention member is in an uncompressed state; the base configured for movement between: an expanded configuration, corresponding to the retention member being in the uncompressed state, wherein clearance or minimal contact exists between the socket and the retention member such that the retention member is selectively rotatable within the socket; and a locked configuration wherein the socket contracts and compresses the retention member to a compressed state, wherein the retention member is immobilized relative to the base when in the compressed state, and further wherein, compression of the retention member causes a compression of the bore to reduce a diameter of the bore along a substantial portion of its length, sufficient to immobilize the medical device relative to the retention member.
