CathLab - Microcoil & Catheters

Renegade catheter (now, "Target Catheter"):
?150 cm, Goes over 0.021" guide wire.
Initially, 3 Fr (1 mm). Decreases to 2.5 Fr (0.83 mm) in the last 20 cm at the tip.
Distal 60 cm is also hydrophilic.
Recommended guide catheter lumen 0.042" (1.1 mm). But, this goes through our 4 Fr RCA catheter which is rated for 0.038" wire ("snug fit").

Microcoil comes loaded in a "plastic needle" with hub. There is short plunger for initial transfer to delivery catheter. After transfer of coil to the catheter, the "Pusher wire" is used for deployment.
