Intervertebral disc device employing prebent sheath
First Claim
Patent Images
1. An intervertebral disc device comprising:
- a sheath configured to be extended into an intervertebral disc from an introducer that is percutaneously delivered into an interior of the intervertebral disc, the sheath being predisposed to adopting a bent configuration when extended from the introducer;
a probe adapted to be extended from the sheath, the sheath causing the probe to adopt a bent configuration; and
a handle coupled to the probe for guiding the probe within the intervertebral disc.

Abstract
An intervertebral disc device is provided comprising a distal sheath sized to be extended from a distal end of an introducer that is percutaneously delivered into an interior of an intervertebral disc, a distal section of the sheath being predisposed to adopting a bent configuration when extended from the introducer; a probe adapted to be extended from a distal end of the sheath, the bent section of the sheath causing the probe to adopt a same bent configuration; and a proximal handle for externally guiding the probe within an intervertebral disc.

17. The intervertebral disc device according to claim 1 wherein the probe is adapted to be extended from a distal end of the sheath.
-
18. The intervertebral disc device according to claim 1 wherein:
-
a section of the sheath is predisposed to adopting the bent configuration, and the sheath causes the probe to adopt the same bent configuration inside of the section when the section has adopted the bent configuration.
-
-
19. The intervertebral disc device according to claim 1 wherein the sheath is mechanically predisposed to adopting the bent configuration inside of the intervertebral disc.
-
20. The intervertebral disc device according to claim 1 further comprising the introducer.
-
21. An intervertebral disc device comprising:
-
a sheath configured to be extended into an intervertebral disc from an introducer that is percutaneously delivered into an interior of the intervertebral disc, the sheath being predisposed to adopting a bent configuration when extended from the introducer;
a guide wire adapted to be extended from the sheath, the sheath causing the guide wire to adopt a bent configuration;
a probe adapted to be extended from the sheath over the guide wire, the sheath causing the probe to adopt a bent configuration; and
a handle coupled to the probe for guiding the probe within the intervertebral disc. - View Dependent Claims (22, 23, 24, 25)

26. A method comprising:
-
extending a sheath into an interior of an intervertebral disc through an introducer, the sheath adopting a predisposed bent configuration at a point that is distal to the introducer; and
extending a probe through the sheath such that the probe adopts a bent configuration distal to the introducer as the probe extends through the extended section of the sheath. - View Dependent Claims (27)

28. A method comprising:
-
extending a sheath into an interior of an intervertebral disc through an introducer, the sheath adopting a predisposed bent configuration at a point that is distal to the introducer;
extending a guide wire through the sheath such that the guide wire adopts a bent configuration distal to the introducer as the guide wire extends through the extended section of the sheath; and
extending a probe over the guide wire through the sheath such that the probe adopts a bent configuration distal to the introducer as the probe extends through the extended section of the sheath. - View Dependent Claims (29)
