Abstract
A device for collecting a tissue sample includes a needle extending along a longitudinal axis from a proximal end to a distal end and including a lumen extending therethrough; an opening in a lateral surface of the needle; and a jaw rotatably coupled to the needle for rotation between a closed configuration in which the jaw covers the opening and an open configuration in which the jaw is received within the lumen to expose the opening. The jaw includes a tissue cutting edge which, as the jaw is rotated from the open configuration to the closed configuration, passes out of the opening along a cutting arc to sever any tissue received in the opening from surrounding tissue.

A device for collecting a tissue sample, comprising:
- a needle extending along a longitudinal axis from a proximal end to a distal end and including a lumen extending therethrough;
- an opening in a lateral surface of the needle;
- and
- a jaw rotatably coupled to the needle for rotation between a closed configuration in which the jaw covers the opening and an open configuration in which the jaw is received within the lumen to expose the opening, the jaw including a tissue cutting edge which, as the jaw is rotated from the open configuration to the closed configuration, passes out of the opening along a cutting arc to sever any tissue received in the opening from surrounding tissue.
A system for collecting a tissue sample, comprising:
- a needle extending along a longitudinal axis from a proximal end to a distal end and including a lumen extending therethrough;
- an opening in a lateral surface of the needle;
- a jaw rotatably coupled to the needle for rotation between a closed configuration in which the jaw covers the opening and an open configuration in which the jaw is received within the lumen to expose the opening, the jaw including a tissue cutting edge which, as the jaw is rotated from the open configuration to the closed configuration, passes out of the opening along a cutting arc to sever any tissue received in the opening from surrounding tissue;
- and
- an endoscope with a working channel through which the needle is received.
A method for collecting a tissue sample, comprising:
- inserting a needle to a target tissue within a living body, the needle extending along a longitudinal axis from a proximal end to a distal end and including a lumen extending therethrough;
- drawing tissue into the lumen through an opening in a lateral surface of the needle;
- and
- rotating a jaw rotatably coupled to the needle so that a tissue cutting edge of the jaw passes out of the opening along a cutting arc to sever the tissue received in the opening from surrounding tissue.
