CLIP FOR HANDLING AN ENDOSCOPIC DEVICE
First Claim
Patent Images
1. A device for storing a stylet comprising:
- a stylet;
an end cap selectively coupleable to a proximal end of a needle, the end cap being coupled to a proximal end of the stylet so that, when the end cap is coupled to the needle, the stylet extends from the end cap through the lumen of the needle;
the end cap including a clip mechanism for gripping a distal portion of the stylet when the end cap is decoupled from the needle, the clip mechanism including a space through which the distal portion of the stylet may pass substantially parallel to the proximal end thereof.

Abstract
A device for storing a stylet comprises a stylet sized and shaped for insertion into a lumen of a needle and an end cap selectively coupleable to a proximal end of a needle, the end cap being coupled to a proximal end of the stylet so that, when the end cap is coupled to the needle, the stylet extends from the end cap through the lumen of the needle, the end cap including a clip mechanism for gripping a distal end of the stylet when the end cap is decoupled from the needle, the clip mechanism including a space through which the distal end of the stylet may pass substantially parallel to the proximal end thereof.

15. A device for storing a stylet, comprising:
-
a stylet; and a clip mechanism attachable to the device for gripping a distal portion of the stylet, the clip mechanism including a space through which the distal portion of the stylet may pass. - View Dependent Claims (16, 17)

18. A method for performing fine needle aspiration, comprising:
-
inserting a stylet into a lumen of a needle until a distal end of the stylet plugs a distal opening of the lumen, a proximal end of the stylet being coupled to an end cap; coupling the end cap to the proximal end of the needle; inserting the needle through intervening tissue to a first target location at which a distal end of the needle is adjacent to a first portion of target tissue to be sampled; after the needle has been advanced to the first target location, removing the end cap from the proximal end of the needle; withdrawing the stylet from the needle; coupling a distal portion of the stylet to a clip mechanism of the end cap; and inserting the needle into the first portion of target tissue to obtain a sample thereof. - View Dependent Claims (19)
