Problem
Current methods for removing thrombi from blood vessels can be inefficient, particularly when dealing with clots of varying composition and adherence. Existing thrombectomy devices may struggle to fully extract clots, leading to incomplete recanalization and potential for distal embolization. Significant blood loss during aspiration procedures also remains a concern.
Solution
Retriever Medical develops and manufactures aspiration catheters and mechanical thrombectomy devices designed for efficient removal of thromboembolic material from the pulmonary and peripheral vasculature. Their ClotHound ACE system features specialized catheters engineered to remove soft, organized, impacted, and wall-adherent clots. The BloodHound BOSS system works in conjunction with the ClotHound system, filtering aspirated thrombus and blood, allowing for immediate reinfusion of blood back to the patient, thereby minimizing blood loss during the procedure. The company's focus is on creating atraumatic designs that optimize clot removal while minimizing damage to the vessel wall.
Target Audience
The primary target audience includes interventional cardiologists, vascular surgeons, and interventional radiologists who perform thrombectomy procedures for pulmonary embolism and deep vein thrombosis.
