A catheter system comprising:
- a liquid light guide catheter comprising a proximal end, a distal end, and at least one emitter disposed adjacent the distal end;
- a sheath configured to be disposed over the liquid light guide catheter and configured to receive a liquid medium, the sheath comprising a proximal end, a distal end, and an attenuating member disposed at or adjacent the distal end of the sheath, wherein the attenuating member comprises an open area between 40 percent and 60 percent, wherein the attenuating member is formed from at least one coil having between 75 and 125 wraps per inch.
A catheter system comprising:
- a liquid light guide catheter comprising a proximal end, a distal end, and at least one emitter disposed adjacent the distal end;
- a sheath configured to be disposed over the liquid light guide catheter and configured to receive a liquid medium, the sheath comprising a proximal end, a distal end, and an attenuating member disposed at or adjacent the distal end of the sheath, wherein the attenuating member comprises a braided structure having a braid density between 40 and 80 picks per inch.
