Systems and methods for customizable flow diverter implants

A method for customizing a flow diverter for delivery into a neurovascular blood vessel to treat an aneurysm, the method comprising:

• providing a flow diverter delivery system comprising:
• an elongate tubular member having a proximal end and a distal end, the elongate tubular member comprising an interior wall defining a lumen;
• a flow diverter comprising a proximal end and a distal end, wherein the flow diverter is partially contained within the lumen of the elongate tubular member in a constrained configuration, wherein the flow diverter extends a first length beyond the distal end of the elongate tubular member;
• a deployment wire extending within the lumen of the elongate tubular member, the deployment wire having a proximal end, a distal end, and a distal portion having a taper, the deployment wire comprising at least one deployment feature coupled to the flow diverter;
• a housing coupled to the elongate tubular member and defining a template;
• and
• a tubing extending along and around a distal portion of the elongate tubular member, wherein the tubing extends a second length beyond the distal end of the elongate tubular member, wherein the distal end of the flow diverter is within the tubing;
• determining a desired length of the flow diverter using the template;
• advancing or retracting the tubing relative to the housing to align the flow diverter to the template;
• cutting the tubing and the flow diverter such that the flow diverter is cut to the desired length;
• and
• retracting the flow diverter into the elongate tubular member or advancing the elongate tubular member over the flow diverter.
