Thrombectomy systems and methods for same

A thrombectomy system comprising:

• a delivery catheter configured to support one or more thrombectomy instruments, the delivery catheter includes:
• a delivery catheter hub;
• and
• a collection catheter having a collection shaft with a collection lumen, the collection shaft is coupled with the delivery catheter hub;
• an aspiration flush valve in communication with the collection lumen, the aspiration flush valve includes:
• an aspiration port;
• a flushing port;
• an outlet port in communication with the collection lumen and in selective communication with the aspiration port and the flushing port;
• and
• a valve operator movable relative to the aspiration, flushing and outlet ports, the valve operator includes flushing and aspiration configurations:
• in the flushing configuration the outlet port is in communication with the flushing port;
• and
• in the aspiration configuration the outlet port is in communication with the aspiration port through a valve operator aspiration lumen separate from the flushing lumen;
• and
• wherein the delivery catheter hub includes a hemostasis valve, the hemostasis valve includes:
• a valve diaphragm configured to seal the collection lumen;
• a valve defeater having a spanning element movable relative to the valve diaphragm between interconnecting and arrested configurations:
• in the interconnecting configuration the spanning element having a spanning lumen crosses the valve diaphragm and the spanning lumen extends through the valve diaphragm;
• and
• in the arrested configuration the spanning element is retracted from the valve diaphragm.
