Interspinous process spacer instrument system with deployment indicator
First Claim
1. An instrument system comprising:
- a spacer configured to be arranged from at least one undeployed configuration to at least one deployed configuration;
an inserter connectable to the spacer;
a driver configured to arrange the spacer from the at least one undeployed configuration to the at least one deployed configuration; and
a deployment indicator including a spring loaded shaft biased against a movable portion of the spacer at one end;
wherein movement of the movable portion of the spacer moves the shaft;
said movement of said shaft being visible at a second end to provide at least one information pertaining to a degree of deployment of the spacer.

Abstract
A percutaneous and minimally invasive instrument system for implanting an interspinous process spacer into a patient is disclosed. The insertion instrument system includes an inserter and a driver. The inserter is configured to releasably clamp to an interspinous process spacer for its delivery, implantation and deployment. The driver is configured for removable insertion into a proximal end of a passageway of the inserter. The driver has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for the deployment of the spacer from at least one undeployed configuration to at least one deployed configuration and vice versa. As the spacer goes from the undeployed to the deployed configuration and vice versa, the system advantageously provides a degree of deployment information to the user via at least one deployment indicator.

14. An instrument system comprising:
-
a spacer having engaging portions movable between an undeployed position and a deployed position; an inserter releasably coupled to the spacer, the inserter having a central bore extending therethrough; a driver having a first end portion opposite a second end portion, wherein the first end portion is movably positioned within at least a section of the central bore of the inserter and includes projections that contact corresponding engaging portions of the spacer to move the engaging portions from the undeployed position to the deployed position in response to movement of the second end portion; and a deployment indicator including a spring loaded shaft biased against a movable portion of the spacer at one end, wherein movement of the movable portion of the spacer moves the shaft, wherein movement of the shaft is visible at a second end to provide at least one information pertaining to the degree of deployment of the spacer. - View Dependent Claims (15, 16, 17, 18, 19, 20)
