Abstract: A stent delivery system including an elongate shaft of a medical device, a stent selectively coupled to a distal portion of the elongate shaft, and a coupling mechanism for selectively coupling the stent to the elongate shaft by inserting a tab on one of the stent or the elongate shaft into an opening in the other of the stent or the elongate shaft. The tab may be deflected from a first position to a second position to disengage the tab from the opening.

Abstract: A medical system including an instrument. The instrument may have a rigid guide tube with a pre-formed shape and at least one change in direction between a proximal end and a distal end of the guide tube. The guide tube may include a first channel extending between the proximal end and the distal end and a second channel extending alongside the first channel. The first channel may include a first opening extending along a side of the guide tube so that the first channel is at least partially exposed. The guide tube may further include an optical device integrally formed with the body. A cross-section of a proximal portion of the guide tube may be greater than a cross-section of a distal portion of the guide tube.

Abstract: Various systems and methods may guide, support, and/or house instruments. One exemplary system includes a guide tube having a manipulation section and mated with rails carrying instrument control members. Moving the rails with respect to the guide tube, or another point of reference, can control movement of the manipulation section.

Abstract: A handle for a medical device includes 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.

Abstract: 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.

Abstract: A biopsy needle comprises a first lumen open to a tissue penetrating distal tip of the needle for receiving a tissue sample therein and a second lumen in combination with a filter separating the first and second lumens from one another, the filter being configured to permit fluids to pass therethrough while preventing the sampled tissue from passing therethrough.
