MEASUREMENT INSTRUMENT FOR PERCUTANEOUS SURGERY
First Claim
1. An apparatus, comprising:
- a measurement member configured to be disposed in a space between adjacent anatomical structures, the measurement member configured to be moved between a collapsed configuration and an expanded configuration; and
a size indicator coupled to the measurement member, the size indicator having a plurality of markings, the size indicator configured to be remotely viewed while the measurement member is disposed in the space between the adjacent anatomical structures to indicate a distance between the adjacent anatomical structures.

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.

8. An apparatus, comprising:
-
a measurement member configured to be percutaneously inserted between adjacent anatomical structures while in a first configuration; an actuator coupled to the measurement member, the actuator configured to exert an axial force on the measurement member to move the measurement member to a second configuration, the measurement member being in contact with the adjacent anatomical structures when in the second configuration; and a size indicator disposed at a location on the actuator associated with a portion of the measurement member, the size indicator including a plurality of markings configured to indicate a distance between the adjacent anatomical structures. - View Dependent Claims (9, 10, 11, 12, 13)
