Endoscopic biopsy needle with coil sheath |
摘要 |
A notched tissue-collection needle configured similarly to a fine-needle-aspiration needle is provided with a cutting edge disposed in the notch and configured to excise tissue into the notch for collection. A stylet may be provided through a lumen of the needle during introduction into a patient body. The needle may be provided with echogenicity-enhancing features. A coated-wire sheath through which the needle is slidably disposed includes an overcoating that is thicker along a distal length and thinner along a proximal length, and may include another thicker proximal-most portion adjacent the handle. |
