摘要:
The present disclosure is directed to devices, kits, and methods for treating lumbar spinal stenosis by at least partially decompressing a compressed nerve root. The method can include identifying the compressed nerve root and percutaneously accessing a region of a lamina located adjacent to the compressed nerve root. The method can also include forming a channel through the region of the lamina, wherein the channel can be formed medial to a lateral border of the lamina. Further, the method can include expanding the channel in a lateral direction.

A kit for treating spinal stenosis is disclosed, the kit comprising: a cannula having a distal portion configured to be inserted along a generally anterior trajectory across interlaminar space between lamina of adjacent vertebra to a first location external to an epidural space; a tissue excision device having a distal portion configured to be inserted through the cannula to a second location external to the epidural space; wherein the distal portion of the tissue excision device is visualized at the second location using imaging means; wherein the tissue excision device is configured to excise and remove tissue about the second location, which decompresses the spinal stenosis.
摘要:
The device comprises an outer tubular and an inner tubular slidingly received within the outer tubular. The inner tubular has a distal end including an upper member and a lower member. Further, the device includes an open position with the distal end fully extended from the outer tubular, and a closed position with the distal end disposed within the outer tubular, wherein the upper member is biased away from the lower member and is disposed at an open angle ¸ o relative to the lower member when the device is in the opened position. A longitudinal axis of the lower member is fixed substantially parallel to a central axis of the outer tubular member, and at least a portion of a distal edge of the upper member and the lower member is sharpened.

Further, the device includes an open position with the distal end fully extended from the outer tubular, and a closed position with the distal end disposed within the outer tubular, wherein the upper member is biased away from the lower member and is disposed at an open angle θ o relative to the lower member when the device is in the opened position. A longitudinal axis of the lower member is fixed substantially parallel to a central axis of the outer tubular member, and at least a portion of a distal edge of the upper member and the lower member is sharpened.
摘要:
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.
摘要:
A surgical device for percutaneously accessing a tissue of interest. In an embodiment, the surgical device comprises a handle including a groove. In addition, the surgical device comprises a resilient member disposed within the groove. Further, the surgical device comprises a locking sleeve at least partially disposed within the groove with a first end compressing the resilient member and a second end extending beyond the groove and including a flange defining a locking recess having a non-circular cross-section. Still further, the surgical device comprises a cannula including a locking end, the locking end including a locking flange having a non-circular cross-section adapted to be at least partially received by the locking recess to prevent the rotation of the cannula relative to the locking sleeve. Moreover, the surgical device comprises a means for rotationally coupling the cannula to the handle.
