    摘要： A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a locking mechanism for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft such that the proximal end of the stent is positioned proximal of the distal end of the elongate shaft. The locking mechanism includes an engaging feature of the elongate shaft which engages a portion of the stent such that the stent may be selectively coupled to the elongate shaft through rotational motion of the elongate shaft relative to the stent. In some instances, the engaging feature of the elongate shaft may be a tab which extends into an opening of the stent.

    摘要： A device for capturing a tissue sample from within a body comprises a needle slidably comprising a needle lumen extending therethrough to a needle opening in the distal end and a stylet slidably received in the needle lumen for movement between an extended position in which a tissue penetrating distal tip of the stylet extends out of the needle opening to penetrate target tissue and a retracted position in which the distal tip of the stylet is received within the needle opening to substantially seal the needle lumen. The stylet further comprises an anchoring feature located proximally of the tissue penetrating distal tip. The anchoring feature comprises a first gripping member including a first proximal facing abutting surface adjacent to a first tissue receiving gap. Movement of the stylet distally out of the needle lumen brings the first gripping member into engagement with surrounding tissue to anchor the stylet at a desired position within the body.

    摘要： A device for gathering tissue samples includes a needle defining a distal tissue penetrating tip. The needle includes an increased diameter proximal portion extending proximally from the distal tip. An outer diameter of the distal tip is smaller than an outer diameter of the proximal portion. The needle defines a lumen extending therethrough from a distal opening in the distal tip thereof to a proximal opening at a proximal end thereof. The lumen includes a distal portion having a first inner diameter and a proximal portion having a second diameter greater than the first diameter. The device also includes a stylet slidably received within the lumen. An outer diameter of a distal portion of the stylet is substantially equal to the inner diameter of the distal portion of the lumen so that, when the stylet is in an extended position extending to the distal opening of the lumen, the lumen is substantially sealed thereby, and when, in a retracted position in which a distal end of the stylet is received within the proximal portion of the lumen, an annular space surrounding the stylet defines an aspiration path for samples exiting the distal portion of the lumen.

    摘要： A handle for a medical device comprises a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.
