1. A kit comprising a trocar, an obturator and a waveguide, wherein:
the trocar has a proximal end, a distal end, and a trocar axis between the ends, the trocar defining a lumen between its proximal and distal ends, the distal end of the trocar being sharpened; the obturator having a proximal end, a distal end, and an obturator axis between the ends, the length of the obturator from its proximal to its distal end being greater than the length of the trocar from its proximal to its distal end, the obturator also being configured to transmit light of a predetermined range of wavelengths from its proximal end to its distal end, the obturator being sized and shaped to substantially fill the trocar in directions radial to the obturator and trocar axes when the obturator is disposed inside the trocar lumen with the obturator and trocar axes aligned; and the proximal end of the obturator being configured to be operably connected to the waveguide. |
