Summary: There are over 1.2 billion peripheral IV catheters (PIVC) placed yearly, with up to a 54% first insertion and overall 90% failure rate primarily due to over-penetration of the vessel. Failure of correct placement leads to local pain, phlebitis, bruising, loss of the vein and extended hospital stays.
The Truecath auto-catheter addresses this problem by using a mild vacuum in the flashback chamber as a mechanical sensor to detect the instant the needle tip enters the vein and automatically place the softgel catheter into the vein lumen. This occurs in 1/16 of a second, which is faster than operator reaction time, thus eliminating the possibility of the practitioner puncturing the back wall of the vessel. As the operator withdraws the introducer, the needle guard automatically advances to cover the sharp needle tip to eliminate accidental needle sticks to the clinician.
Outside of retractable needles for safety, there have been no significant innovations in the core angiocatheter technology in the last 50 years.
