Abstract
A method includes positioning a medical device within a body between adjacent spinous processes, moving the medical device from a collapsed configuration to an expanded configuration within the body using an actuator removably coupled to the medical device, and removing the actuator from the body while the medical device remains between the adjacent spinous processes.
Claims4
A method, comprising:
- percutaneously inserting an elongate member between adjacent spinous processes, the elongate member having a proximal portion, a distal portion and a non-expanding central portion disposed sequentially along a longitudinal axis with the central portion disposed between and separating the proximal and distal portions;
- moving the proximal portion from a first configuration to a second configuration;
- the second configuration relatively larger than the first configuration in a plane normal to the longitudinal axis;
- thereafter, moving the distal portion from a first configuration to a second configuration;
- the second configuration of the distal portion relatively larger than the first configuration of the distal portion in the plane normal to the longitudinal axis.
