摘要:
Spring clips are arranged end to end in a cavity of an inner shaft. Such shaft slides within an outer shaft, and a pusher member slides in the cavity behind the clips. The clips have jaws biased together, but which are wedged apart by an opener as the pusher is moved distally. An opened clip is ejected by relative movement of the inner and outer shafts to clamp body tissue at a desired site.
摘要:
An endoscopic biopsy device having an outer sheath that is transparent, at least along a portion thereof, to allow visualization of at least a portion of the inside of the device. A distal portion of the outer sheath may be relatively more opaque or relatively less reflective to avoid glare that may otherwise result due to the sheath reflecting light from the endoscopic light source.

Methods for the treatment of asthma are provided, which comprise: (a) providing an implantable or insertable medical device that comprises an asthma treatment agent; and (b) inserting or implanting the medical device within the lungs (e.g., the trachea or the bronchial tree) of a patient, whereupon the therapeutic agent is delivered to the patient in an amount effective to reduce or eliminate the symptoms of asthma. Also disclosed herein are medical devices and kits for carrying out such methods.

An implantable stent includes a stent retrieval member for repositioning or retrieval of the stent after it has been implanted into a bodily lumen. The stent includes a distensible tubular stent having a tubular structure having a tubular wall defined by an interior surface and an exterior surface and having opposed open ends; and a stent retrieval member comprising an elongate member comprising a generally circular perimetric base and a shaped projection having first and second spaced apart members extending acutely or perpendicularly from the base and connected by an apical portion. Force exerted on the shaped projection causes contraction or expansion of the circular base. The circular base is securably attached to one of the open ends of the stent, and the shaped projection extends longitudinally beyond this open end of the stent.
