摘要：
A medical device such as a needle subassembly is disclosed including a cover over a magnetized portion of a tissue-penetrating medical device having a shielding material associated with the cover that prevents the magnetized portion of the tissue-penetrating medical device from being de-magnetized when the cover is positioned to cover the tissue-penetrating medical device.
