Inari Medical has filed a patent for clot treatment systems with filtering syringes. The filtering syringe is designed to aspirate clot material and blood from a patient via a catheter subsystem. The syringe includes a plunger assembly with filters that allow blood to pass through while preventing clot material from passing through. The syringe can be connected to a filtered material subsystem for fluid outflow. GlobalData’s report on Inari Medical gives a 360-degree view of the company including its patenting strategy.

Filtering syringe for clot treatment in blood vessels
A recently filed patent (Publication Number: US20230310751A1) describes a filtering syringe designed for the treatment of clot material within a patient's blood vessel. The syringe consists of a barrel with a chamber to receive the clot material and blood, and a plunger assembly with a filter near one end and a port near the other end. The plunger assembly can slide within the barrel, allowing the filter to separate blood from the clot material and direct it into the lumen of the plunger assembly. The filter can have various shapes, such as circular, annular, cylindrical, or pleated, and a porosity ranging from 40 to 200 microns. It can be made of materials like polyester, polyamide, or other hemocompatible materials. The syringe may also include multiple filters with different porosities.
The patent also describes a system for intravascular clot treatment, which includes the filtering syringe and a catheter positioned near the clot material. The syringe generates negative pressure to aspirate the clot material and blood through the catheter. The system can be connected to a filtered material system that receives the filtered blood and includes a fluid drive component to facilitate the flow of filtered blood. The system may have flow paths directing the fluid away from the syringe. The syringe itself may have a valve opposite the tip to prevent filtered blood from re-entering the syringe.
The patent further outlines a method for removing clot material from a patient's blood vessel using the filtering syringe. The method involves positioning the catheter near the clot material, connecting the syringe to the catheter via a fluid control device, generating a vacuum with the syringe, and opening the fluid control device to apply the vacuum to the catheter and aspirate the clot material. The blood is then filtered from the clot material using the syringe's filter.
Overall, this patent presents a filtering syringe and system for the treatment of clot material within a patient's blood vessel. The syringe's design allows for effective separation of blood from the clot material, and the system provides a comprehensive approach to intravascular clot treatment.
