摘要： A catheter for delivering energy to a surgical site is disclosed. The catheter includes at a proximal end a handle and at a distal end a probe. The catheter includes at least one energy delivery device and an activation element. The at least one energy delivery device is located at the distal end of the catheter to deliver energy to portions of the surgical site. The activation element is located at the distal end of the catheter, to transition the probe from a linear to a multi-dimensional shape, within the surgical site. Methods for deploying the probe from the linear to multi-dimensional shape are disclosed. In another embodiment of the invention the catheter includes a heating element fabricated on a substrate by photo-etching to deliver thermal energy to portions of the surgical site. In another embodiment of the invention the catheter includes an energy delivery element, a tip and a blade. The energy delivery element is located at the distal end of the catheter to deliver energy to portions of the intervertebral disc. The blade is positioned within a first lumen of the tip and is extensible beyond the tip, to cut selected portions within the intervertebral disc. In another embodiment of the invention a catheter includes both energy and material transfer elements and an interface on the handle thereof. The interface couples the energy delivery element and the material transfer element to external devices for energy and material transfer to and from the intervertebral disc.

摘要： An electrosurgical instrument is provided, having a holding formation, an elongated probe, an electrode, and a conductor. The elongated probe is connected to and extends from the holding formation. The electrode is located on an end of the elongated probe opposing the holding formation, and has a leading edge and a face. The electrode is locatable so that the face is substantially in a horizontal plane and the leading edge is above the horizontal plane. The conductor extends along the elongated probe and has a portion connected to the electrode to provide RF power thereto. The electrode creates a temperature profile with a temperature adjacent to the leading edge being higher than a temperature adjacent to the face.

摘要： An intervertebral disc device is provided comprising a distal probe (236) sized to be extended from a distal end of an introducer (230) that is percutaneously delivered into an interior of an intervertebral disc (120), a distal section of the probe comprising a flexible neck (312) which tapers in a proximal to distal direction, and a distal tip (316) which is larger in cross sectional diameter than the flexible neck adjacent the distal tip, the flexible neck and distal tip serving to prevent the probe distal end from piercing an internal wall of the intervertebral disc; and a proximal handle (212) for externally guiding the probe (236) within an intervertebral disc.

摘要： An intervertebral disc device is provided comprising a probe capable of being extended from a distal end of an introducer that is percutaneously delivered into an interior of an intervertebral disc, the probe forming a loop when extended from the distal end of the introducer, the loop having first and second proximal ends external to the introducer which are brought together adjacent the introducer distal end to form the loop by the proximal ends being either attached to or entering the distal end of the introducer; and a proximal handle for externally causing the probe to be extended from the distal end of the introducer and externally guiding the probe within an intervertebral disc.
