Percutaneous Devices for Separating Tissue, Kits and Methods of Using the Same
First Claim
1. A device for separating a first tissue from a second tissue at a surgical site, comprising:
- a hollow body having a distal end and a proximal end, wherein the distal end further comprises an upper separation member extendable laterally from the hollow body at a first angle;
an inner member slidably having a distal end and a proximal end and disposed within the hollow body, wherein the distal end of the inner member has a lower separation member extendable laterally from inner member at a second angle, wherein the upper separation member and the lower separation member have a first configuration and a second configuration.

Abstract
The disclosure describes devices for separating a first tissue from a second tissue at a surgical site, comprising, a hollow body having a distal end and a proximal end, wherein the distal end further comprises an upper separation member extendable laterally from hollow body at a first angle; an inner member slidably disposed within the hollow body, wherein the distal end of the inner member has a lower separation member extendable laterally from inner member at a second angle, wherein the upper separation member and the lower separation member have a first configuration and a second configuration into a tissue in the working zone on the first lateral side of the median plane. Additionally, methods for using the device and kits containing the device are disclosed.

16. A method for treating stenosis in a spine of a patient having a median plane comprising the steps of:
-
compressing a dural sac in the region of interest by injecting a fluid to form a safety zone and establish a working zone in the region of interest, the safety zone lying between the working zone and the dural sac; percutaneously accessing an epidural space in the region of interest on a first lateral side of a median plane; and inserting a device for separating a first tissue from a second tissue at a surgical site, comprising, a hollow body having a distal end and a proximal end, wherein the distal end further comprises an upper separation member extendable laterally from hollow body at a first angle;
an inner member having a distal end and a proximal end and slidably disposed within the hollow body, wherein the distal end of the inner member has a lower separation member extendable laterally from inner member at a second angle, wherein the upper separation member and the lower separation member have a first configuration and a second configuration into a tissue in the working zone on the first lateral side of the median plane. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
