noncoring
Noncoring refers to a class of needle design and technique used to access implanted venous access ports and other silicone septa without removing material from the septum. The term describes the device’s ability to puncture the self-sealing silicone septum without coring, meaning it does not cut out a plug of silicone or create a hole that compromises the septum’s integrity.
Design and mechanism: Noncoring needles, commonly called Huber needles in port access, feature a non-cutting, deflected
Applications: The principal use of noncoring needles is to access implanted venous access ports for chemotherapy,
Advantages and limitations: Benefits include reduced risk of septum damage and leakage, longer port life, and
