Title:
INTERSPINOUS IMPLANT INSERTION INSTRUMENT WITH STAGGERED PATH IMPLANT DEPLOYMENT MECHANISM
Document Type and Number:
WIPO Patent Application WO/2017/181016
Kind Code:
A3
Abstract:
An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A plunger is slidably engaged in a central passage of the elongated main body configured to fix the implant to the elongated main body by selectively filling the central passage within the distal portion. A hex nut driver is concentrically located about the plunger and elongated main body to deploy an actuation plunger of the implant. The proximal handle portion of the main body includes a staggered path therethrough for accepting a tab of the plunger therein. Advancement and retraction of the plunger tab within the staggered path alternates the insertion instrument between an unlocked position configured to mount the implant on the distal portion of the elongated main body, a locked position configured to lock the implant on the distal portion, and a deployed position configured to secure the implant.
