Abstract
Abstract A medical needle set for visualized tissue ablation within a subject's body includes a cannula and components configured for inclusion in the cannula, including a trocar for occlusion of the cannula lumen during needle placement, and a visualizing ablation probe used for simultaneous endoscopic viewing and ablation of tissue sites with a laser beam. The cannula can include a tissue-gripping surface for stabilization of the needle set on the target tissue. A surgical system for tissue ablation includes a visualizing ablation needle set operably connected to an endoscope and a laser. A surgical procedure using this system permits simultaneous visualization and ablation of tissues, including those of the facet joints of the spine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
A visualizing ablation needle set comprising: a cannula comprising a hollow shaft defining a longitudinal lumen, said shaft having a proximal segment and a distal segment, wherein said distal segment comprises a distal tip configured with a tissue-gripping surface a trocar configured for inclusion in said longitudinal lumen, and; a visualizing ablation probe configured for inclusion in said longitudinal lumen, said probe comprising an obturator configured to accommodate a laser energy delivery device and an endoscope.
Claim 2
Dependent Claim
76 words
A visualizing ablation needle set comprising: a cannula comprising a hollow shaft defining a longitudinal lumen, said shaft having a proximal segment and a distal segment, wherein said distal segment comprises a distal tip configured with a tissue-gripping surface a trocar configured for inclusion in said longitudinal lumen, and; a visualizing ablation probe configured for inclusion in said longitudinal lumen, said probe comprising an obturator configured to accommodate a laser energy delivery device and an endoscope.
Claim 3
Dependent Claim
87 words
A visualizing ablation needle set comprising: a cannula comprising a hollow shaft defining a longitudinal lumen, said shaft having a proximal segment and a distal segment, wherein said cannula further comprises a side port disposed in said hollow shaft, said side port having a configuration for attaching a suctioning device; a trocar configured for inclusion in said longitudinal lumen, and; a visualizing ablation probe configured for inclusion in said longitudinal lumen, said probe comprising an obturator configured to accommodate a laser energy delivery device and an endoscope.
Claim 4
Dependent Claim
