An apparatus for tissue anchoring of a medical device includes a retention member and an elastic member secured between ends of the retention member. The retention member, being transformable along a longitudinal axis of the apparatus, is held by a spring bias of the elastic member in a first, gripping state; and, when opposing forces compress the elastic member, the retention member is transformed to a second, open state. In the first state, a lumen defined by a sidewall of the retention member has a diameter to forms a interference fit around a body of the device, and the ends of the retention member are spaced apart by a first distance; in the second state, the ends are spaced closer together than in the first state, and the diameter of the lumen is enlarged to allow movement of the apparatus along a length of the device body.
