• Manual aspiration thrombectomy (Pronto [Teleflex], export aspiration catheters [Medtronic], FETCH 2 Aspiration catheter [Boston Scientific], eliminate Aspiration catheter [Terumo], ASAP Aspiration catheter [Merit Medical], QuickCat Extraction catheter [Philips]): Suction created by a syringe
• Mechanical aspiration thrombectomy(Penumbra): Mechanical power aspiration with a continuous vacuum source and large lumen aspiration catheter
• Rheolytic Thrombectomy (Angioject): A high velocity saline creating a low pressure zone (Bernoulli principle) to create a vacuum

• Mechanical devices pulverize the thrombus with a jet of saline and aspirate through other ports by the mechanism of Venturi–Bernouli effect
• Manual device aspirate by negative suction with a 30 cc locking syringe

• It is a manual aspiration device that is connected to 30 cc locking syringe to create negative suction, followed by slow pull back movement
• After the catheter is removed, the back end of the guide is opened, and a generous amount of bleed back is allowed
• Minimum of 2–3 runs are required

Indications

• STEMI in setting of primary PCI
• Vein graft intervention with large thrombus
• Coronary ectasia/aneurysm with thrombus and requiring intervention
• For drug delivery in distal vessel

 
Disadvantages
 

• Difficult to deliver in tortuous vessels, distal segment, and calcified vessels
• Dissection
• Migration of thrombus
• Stent deformation (proximal) if attempt is made to pass beyond the stent
