Devices, kits and methods relating to treatment of facet joints

A kit useful in performance of a medical procedure in the vicinity of a facet joint, the kit comprising:

• a first rotatable member comprising a first distal end portion having a first distal tip, the first rotatable member being rotatable about a first axis of the first rotatable member;
• and
• a second rotatable member comprising a second distal end portion having a second distal tip, the second rotatable member being rotatable about a second axis of the second rotatable member;
• a sheath with an internal passage through which the said rotatable members are receivable with the distal tips of the said rotatable members disposed distal to distal end of the sheath and proximal ends of the said rotatable members disposed proximal of a proximal end of the sheath, and wherein when so received through the sheath the first and second rotatable members are rotatable relative to each other about the first and second axes respectively to manipulate the relative positioning of the first and second distal end portions between a facet joint penetration configuration in which the first and second distal end portions are positioned to form a piercing tip to pierce through tissue and penetrate into the facet joint and a facet joint retraction configuration in which the first and second distal end portions are positioned to retract the facet joint following penetration into the facet joint;
• the sheath having a minimum area cross-section through which the said rotatable members are receivable that has an aspect ratio of at least 1.5:1 and is sized to constrain the said rotatable members in a side-by-side orientation through the minimum area cross-section with the said rotatable members being translatable through the minimum area cross-section in a longitudinal direction through the internal passage.
