摘要： Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include a guide member having a proximal portion and a distal portion. A stent may be disposed about the distal portion of the guide member. The stent may have a wall having an opening formed therein. A pusher member may be disposed about the guide member and positioned proximal of the stent. A holding filament may be disposed at the opening and may extend to the proximal portion of the guide member. The holding filament may be configured to releasably secure the position of the stent relative to the pusher member. The holding filament may be releasable from the stent independently of movement of the guide member.

摘要： A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and a retention mechanism for selectively retaining the drainage stent on the elongate shaft. The tubular stent is positioned on and surrounding the elongate shaft. The elongate shaft includes a distal tip portion which is deflectable from a first position to a second position, the distal tip portion of the elongate shaft being biased toward the first position. Deflecting the distal tip portion of the elongate shaft from the first position to the second position moves the distal tip portion toward the central longitudinal axis of the tubular stent to allow the stent to be decoupled from the elongate shaft.

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.
