Optically cleaved catheter coiling system

A method of coil embolization using a catheter, the method comprising:

• inserting a catheter into a patient intravenously or intraarterially;
• navigating the catheter to a site of an aneurysm, the catheter defining an outer wall;
• placing a tip of the catheter at an opening of the aneurysm;
• delivering into the aneurysm, via a pusher wire, through a lumen of the catheter, a coil;
• determining a user defined detachment point at which a distal coil segment of the coil should be detached from the coil;
• aligning the user defined detachment point of the coil with a designated detachment zone at the tip the catheter where an exposed portion of an embedded optical fiber is located, wherein the optical fiber defines at least one of a notch or an angled cut in the exposed portion;
• and
• toggling a laser source connected to the embedded optical fiber, thereby detaching the distal coil segment from the coil via an emitted laser beam emitted from the embedded optical fiber at the at least one of the notch or the angled cut to the designated detachment zone at the tip of the catheter.

A system comprising:

• a catheter defining a distal tip;
• and
• a laser source;
• wherein the catheter comprises:
• an outer wall;
• a pusher wire interior to the outer wall;
• and
• an optical fiber embedded in the catheter,
• wherein an exposed portion of the distal end of the optical fiber defines at least one of a notch or angled cut such that a laser beam passed through the optical fiber is emitted inwards from the at least one of the notch or the angled cut to cut an object or material being passed through the distal tip of the catheter,
• wherein the laser source is connected to the optical fiber embedded in the catheter.
