  • Interventional medical procedure is a popular procedure that can diagnose and treat diseases in various organs of a patient. Interventional medical procedures are minimally- invasive image guided medical procedures that minimize risk to the patient in comparison to open surgeries.
  • Trocars can be used to create lumens through which a catheter can be eventually inserted.
  • the Seidinger technique has been widely employed in order to gain safe access to the vascular system.
  • the Seidinger technique involves puncturing a desired blood vessel with a needle. A guidewire is inserted through the needle such that the guidewire is placed into the blood vessel. Once the guidewire has advanced to the desired length and/or location in the blood vessel, the needle is removed. A catheter is then advanced into the blood vessel over the guidewire. Once the catheter is in the blood vessel, the guidewire is pulled out.
