Endoscopic ultrasound fine needle aspiration device

A handle for a medical device, comprising:

• a proximal segment defining a proximal lumen extending longitudinally therethrough, the proximal lumen being sized and shaped to receive an endoscopic medical device therein;
• a medial segment received within a distal portion of the proximal segment, the medial segment having an outer diameter smaller than an inner diameter of the proximal segment and defining a medial lumen extending therethrough open to the proximal lumen;
• and
• a distal segment received within a distal portion of the medial segment and defining a distal lumen extending therethrough open to the medial lumen, the distal segment having an outer diameter smaller than an inner diameter of the medial segment, wherein the medial segment includes a first movement limiting mechanism configured to limit advancement and retraction of an endoscope attached to a distal end of the distal segment and wherein the medial segment includes a second movement limiting mechanism limiting movement of the endoscopic medical device inserted through the proximal, medial and distal lumens along an axis of the distal lumen,
• wherein the distal segment includes an attachment sized and shaped to engage a corresponding attachment at a proximal end of the endoscope to which the handle is to be mounted, and
• wherein the proximal segment is rotatably coupled to the distal segment and is adapted to non-rotatably couple to a needle to be mounted therein so that rotation of the proximal segment rotates the needle inserted therein within the distal segment and a working channel of the endoscope coupled thereto.
