1. A method, comprising:
- positioning an implant having an end portion and a body portion such that the body portion is disposed between a pair of adjacent spinous processes;
wherein the body portion and the end portion are in respective collapsed configurations during the positioning;
moving the body portion of the implant from its collapsed configuration to an expanded configuration at a first time after the positioning;
moving the end portion of the implant from its collapsed configuration to an expanded configuration at a second time after the positioning;
wherein the second time different than the first time and the first and second times do not overlap.

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.

10. A method, comprising:
-
positioning an implant having an end portion and a body portion such that the body portion is disposed at a position along a lateral insertion path between a pair of adjacent spinous processes;
wherein the body portion and the end portion are in respective collapsed configurations during the positioning;distracting the pair of adjacent spinous processes with the body portion of the implant while maintaining the body portion of the implant at the position along a lateral insertion path; thereafter, moving the end portion of the implant from its collapsed configuration to an expanded configuration such that lateral movement of the implant relative to the pair of adjacent spinous processes is limited in at least one direction. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method, comprising:
-
positioning an implant having a first portion and a second portion such that at least a portion of the implant is disposed between a pair of adjacent spinous processes;
wherein the first and second portions are in respective collapsed configurations during the positioning;moving the first portion of the implant from a collapsed configuration to an expanded configuration using a first actuator after the positioning; and moving the second portion of the implant from a collapsed configuration to an expanded configuration using a second actuator after the positioning, the second actuator different from the first actuator; wherein an overall longitudinal length of the implant, from an end of the first portion opposite the second portion to the end of the second portion opposite the first portion;
does not change during one of the moving the first portion to its expanded configuration and the moving the second portion to its expanded configuration;wherein the overall longitudinal length of the implant changes during the other of the moving the first portion to its expanded configuration and the moving the second portion to its expanded configuration. - View Dependent Claims (18, 19, 20, 21)

22. A method, comprising:
-
positioning an implant having a first portion and a second portion within a body such that at least a portion of the implant is disposed between a pair of adjacent spinous processes; moving the first portion of the implant from a collapsed configuration to an expanded configuration using a first actuator after the positioning; and moving the second portion of the implant from a collapsed configuration to an expanded configuration using a second actuator after the positioning, the second actuator different from the first actuator; wherein the first actuator includes an inflation tube configured to be placed in fluid communication with a portion of the first portion of the implant; and wherein the second actuator includes a draw bar configured to exert an axial load to the second portion of the implant.
