Abstract
A thrombectomy kit and method provides for aspirating a thrombus without use of a syringe that is precharged with a vacuum.
Claims19
A thrombectomy kit comprising:
- a thrombectomy catheter having a distal end;
- at least one syringe;
- a valve configured to operably couple between the syringe and the distal end of the thrombectomy catheter;

A thrombectomy apparatus comprising:
- a valve configured for use with a thrombectomy catheter;
- a syringe configured to aspirate a thrombus;
- wherein the valve and the syringe include indicators to visually identify which is to be used first when initiating removal of a thrombus without use of a precharged vacuum.
A thrombectomy method comprising:
- disposing a thrombectomy catheter within a patient having at least one thrombus to be removed from the patient such that an inserted end of the thrombectomy catheter is located proximal to the at least one thrombus;
- connecting a syringe to the thrombectomy catheter via a closed valve;
- opening the valve without first having precharged the syringe with a vacuum;
- applying a gradually increasing pressure to the syringe while monitoring a resistance to applying the pressure to the syringe and thrombectomy catheter;
- modifying one or more pressure-related parameters related to an application of pressure to the syringe based on a result of the monitoring;
- aspirating at least a portion of the at least one thrombus using the application of pressure to the syringe as customized based on the monitoring.
