Abstract
In one embodiment, an apparatus includes a projection having a tapered end portion configured to be inserted percutaneously through tissue. A measurement member is coupled to the projection and is configured to indicate a distance between adjacent anatomical structures. In another embodiment, an apparatus includes a measurement member configured to be percutaneously inserted between adjacent anatomical structures. The measurement member includes a wedge portion that is configured to contact the adjacent anatomical structures when the measurement member is moved distally between the adjacent anatomical structures. A size indicator is coupled to the wedge portion. The size indicator has a plurality of markings and is configured to be viewed on an image of the adjacent anatomical structures with the wedge portion of the measurement member disposed between the adjacent anatomical structures to indicate a distance between the adjacent anatomical structures.
