Insertion of intravenous (IV) catheter is a common clinical procedure carried out 190 million times per year in the United States alone.

While the procedure is common, it is associated with high failure rates:

  • 30% failure in Adults
  • 44% failure in Children

 Common causes for failure:

  • Misidentification of the vein
  • Late feedback of needle penetration
  • Vein piercing due to anatomy and manual challenge


Our solution addresses the 3 procedure needs:

1.    Vein identification:

The SAGIV uses line of sight near infrared (NIR) imaging to provide caregivers with enhanced visualization of sub-cutaneous veins.

Contrast is created due to 100-fold higher absorption of hemoglobin in blood compared to peripheral tissue which is composed primarily of water. 

 2.    Needle insertion identification:

The SAGIV uses catheter imbedded electrodes to sense changes in alternating current resistance (impedance) to monitor vein insertion in real time (milliseconds).

 3.    Robotic Cannula Insertion:

The SAGIV uses simple robotics to insert the needle into the target vein, deposit the catheter and simultaneously withdraw the needle safely into a plastic cartridge.

We design the SAGIV for 2 degrees of freedom, forward - backward axis and upward rotation.
