Abstract
A needle for fine-needle aspiration includes an elongated body extending from a proximal end to a distal end along a central longitudinal axis and having a channel extending therethrough, a distal portion of the body being movable between a first configuration in which the distal portion extends parallel to the central longitudinal axis and the channel is unobstructed and a second configuration in which the distal portion is axially offset relative to the central longitudinal axis to seal at least a portion of the channel and an actuation mechanism controlling movement of the distal portion between the first and second configurations.
Claims9
A needle for fine-needle aspiration, comprising:
- an elongated body extending from a proximal end to a distal end along a central longitudinal axis and having a channel extending therethrough, a distal portion of the body being movable between a first configuration in which the distal portion extends parallel to the central longitudinal axis and the channel is unobstructed and a second configuration in which the distal portion is axially offset relative to the central longitudinal axis to seal at least a portion of the channel, wherein the distal portion extends along one side of the needle for a distance shorter than a diameter of the needle;
- and
- an actuation mechanism controlling movement of the distal portion between the first and second configurations.
A method for performing a biopsy procedure, comprising:
- inserting a needle to a target location in the body, the needle extending from a proximal end to a distal end and having a channel extending therethrough along a central longitudinal axis;
- drawing tissue into the channel;
- and
- actuating a controller located externally of the body to move an actuatable member located at the distal end of the needle from a first configuration in which the channel is unobstructed and a second configuration in which the actuatable member moves into the channel to cut tissue located adjacent thereto, severing the tissue drawn into the channel from the tissue site,
- wherein the actuatable member extends along one side of the needle a distance shorter than a diameter of the needle.
