non-core needles

What is the difference between non-core and core needles?
Thank you,

Regular hypodermic needles, when pushed through something like
rubber will 'core' meaning some rubber will be in the core of the
needle and the needle diameter hole will be seen in the rubber.
Leaking will result.

A non-coring needle will not core (or cause a hole) in a piece of
rubber and that is why a non-coring needle (such as a Huber needle) is
used for implanted devices such as a portacath.

If the needles used for portacaths (intravenous device implanted under
the skin that have a rubber area used for central vein/IV access) cored
each time the portacath was used (sometimes daily), the device would
soon leak and no longer be a good access for central vein infusions.

I hoped this helped. Please let me know if you have other questions.
