Abstract
An anchor is provided for securing an elongated cylindrical member, such as a lead cable, to surrounding tissue. The anchor has a simple design that allows the anchor to be held in place on, e.g., a lead cable, without the need for sutures. In addition, the anchor may be manipulated to allow the anchor to move along the cylindrical member. Manipulation of the anchor is straight-forward, simple, and does not require tools, yet the anchor is reliably held in place, requiring intentional manipulation to be released. The anchor includes two coaxial sleeves holding the ends of a coaxial spring. As one sleeve is rotated in relation to the other, the spring is twisted, causing the inner diameter of the spring to increase or decrease. Once the inner diameter of the spring is increased to the point that is becomes larger than the outer diameter of the cylindrical member it surrounds, the anchor can slide on the cylindrical member. By decreasing the inner diameter of the spring, the spring can grip the cylindrical member, thus securing the anchor in place on the cylindrical member. The anchor includes a locking mechanism for holding the sleeves, and thus the spring, in a certain position or positions.
