Aspiration

ASPIRE Aspirator  (Can be packaged with QuickCat Extraction catheter below)

Improving aspiration with a cost-effective hand-held hand-operated device is not easy. Aspiration is typically performed with basic syringes or electromechanical pumps and systems:

  • Electromechanical systems can provide high aspiration force and volume, but are expensive, difficult to set up, require training, require service, and do not let the clinician feel or control aspiration like a hand-held device.


  • Small syringes are easy to operate but are limited in aspiration volume and will lose aspiration force quickly if air enters into the needle, catheter, trocar, or tube through cavitation, degassing, or connectivity leakage.


  • Large syringes can aspirate more volume and are less susceptible to loss of force if air enters the barrel, but are difficult to operate requiring two hands to pull the plunger back.


  • All standard syringes lack the ability to quickly purge air that enters into the circuit, allow the user to instantly increase or decrease force without accidentally re-injecting the aspirant, or perform pulsed aspiration.
