System and method for treating ischemic stroke
A thromboembolic removal system for treating ischemic stroke, including a guide and occlusion catheter, a delivery and aspiration catheter, an aspiration pump, a thromboembolic receiver, and a thromboembolic separator.
1. A method of manufacture of a system for removal of thromboembolic material from a blood vessel, the method comprising the steps of:
cutting a plurality of uprights and apexes from a length of tubing to form a separator element with a lumen, a proximal end, and a distal end;
adjoining some of the apexes to one another to form three or more cages, wherein each cage forms an internal apex that is centrally disposed within the lumen and is pointed towards the distal end; and
mounting said separator element to an elongate element.
2. The method according to claim 1 , wherein the step of cutting a plurality of uprights and apexes further comprises cutting said uprights generally parallel to one another throughout the length of the tubing, and cutting said apexes so that they extend at an angle to the uprights.
3. The method according to claim 1 , wherein the step of cutting the apexes further comprises cutting the apexes in the wall of the tubing opposite one another.
4. The method according to claim 1 , wherein the step of cutting the apexes further comprises cutting apex extensions.
5. The method according to claim 1 , wherein the step of cutting the uprights and apexes further comprises cutting some of the apexes intermediate the length of the uprights.
6. The method according to claim 1 , wherein the step of mounting the separator element further comprises mounting the separator element to the elongate element via one or more of the uprights.
7. The method according to claim 1 , wherein the step of cutting the apexes comprises cutting a series of pairs of apexes along a longitudinal axis of the tubing, wherein each pair of apexes is oriented at 90° around the axis to each subsequent pair of apexes.
