Aspira Catheter Instructions
What Is An Aspiration Catheter？
The Cylone™ Aspiration Catheter is intended for use in the removal/aspiration of emboli and thrombi from selected blood vessels in the arterial system including the peripheral and neurovasculatures. Moreover, the Cylone™ Aspiration Catheter can be used to facilitate the introduction of diagnostic or therapeutic agents.
Aspiration Catheter Use
Aspiration catheters are medical devices used in various medical procedures to remove thrombus, which is a blood clot that may obstruct blood vessels. These catheters are designed with a unique tip that creates a negative pressure when connected to an aspiration pump. The negative pressure enables the catheter to aspirate or withdraw the thrombus, restoring blood flow and preventing potential complications.
Aspiration catheters are commonly used in interventional cardiology and neurology procedures. In cardiology, they are employed during percutaneous coronary interventions (PCI) to remove thrombus or debris from narrowed coronary arteries, improving blood flow and restoring heart function. In neurology, aspiration catheters are utilized in the management of stroke patients, where they help retrieve thrombi obstructing blood flow in cerebral arteries, reducing the risk of ischemic stroke.
Aspiration Catheter Procedure
a. Preoperative Preparation: Before placing the aspiration catheter, the doctor assesses the patient's condition, using imaging techniques such as X-rays, CT scans, or angiography to determine the location and size of the thrombus. Additionally, the doctor collects the patient's medical history and allergy information to ensure a safe and accurate procedure.
b. Local Anesthesia: During the surgery, the doctor administers local anesthesia to the placement site to minimize patient discomfort.
c. Guidewire Placement: The doctor inserts a guidewire into the blood vessel and navigates it through the vascular system to the location of the thrombus. This helps in precise positioning and guiding the aspiration catheter.
d. Placing the Aspiration Catheter: Once the guidewire is in the desired location, the doctor gently advances the aspiration catheter along the guidewire. This process is usually performed under real-time imaging guidance to ensure accurate placement.
a. Connecting the Aspiration Pump: After the aspiration catheter is properly positioned, the doctor connects it to the aspiration pump. This generates negative pressure, allowing the aspiration catheter to suction the thrombus and other unwanted materials.
b. Thrombus Aspiration: Through the negative pressure generated by the aspiration pump, the aspiration catheter suctions and removes the thrombus from the blood vessel. This process is typically performed progressively until the thrombus is entirely removed.
c. Monitoring and Adjusting: Throughout the aspiration process, the doctor closely monitors blood flow and the position of the aspiration catheter. If necessary, the doctor may make slight adjustments to ensure thorough removal of the thrombus.
d. Completing the Procedure: Once the thrombus is completely cleared, the doctor removes both the aspiration catheter and guidewire from the patient's blood vessel. Mild pressure may be applied to prevent bleeding, and the wound is then covered for further treatment.
