Abstract
Tissue modification instruments. In some embodiments, the instrument may comprise a shaft extending along an axis. A tissue treatment tip may be positioned at a distal end of the shaft. The tissue treatment tip may comprise one or more energy delivery elements configured to deliver tissue-modification energy. The tissue treatment tip may comprise a non-branching tip that extends away from the axis to define a tissue treatment region that is wider than a width of the shaft. The tissue treatment tip may comprise a terminal end, which may be positioned at the distal end of the instrument in some embodiments or may be positioned proximal of the distal end of the instrument.
Claims18
A tissue modification instrument for delivery of tissue-modification energy during a surgical procedure, comprising:
- a shaft extending along an axis;
- a tissue treatment tip at a distal end of the shaft, the tissue treatment tip comprising a plurality of discrete energy delivery elements facing an upper tissue plane and/or a plurality of discrete energy delivery elements facing a lower tissue plane and configured to deliver pulsed tissue-modification energy towards the upper and/or lower tissue planes, wherein each of the energy delivery elements comprises either a conical frustum having a recessed apical cavity or a cylindrical frustum having a recessed apical cavity, wherein the tissue treatment tip comprises a non-branching tip that comprises one or more bends that extend the tissue treatment tip away from the axis and one or more bends that extend the tissue treatment tip towards the axis to define a tissue treatment region that is wider than a width of the shaft, and wherein the tissue treatment tip comprises a terminal end.
