A Groshong line is a type of intravenous catheter used for central venous access.
[1] Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.
In contrast to the Hickman line, the tip of a Groshong line has a three-way valve, which is formed by a slit in the sidewall of the catheter tip.
The Groshong catheter is a trademark of Bard Access Systems.
The device is named after its inventor, LeRoy E. Groshong, MD, a surgical oncologist based in Oregon.
