摘要:
A stent for treating a bodily lumen with a flexible section in a high strain region is disclosed. A flexible section may be selectively positioned to reduce an amount of strain in the high strain region when subjected to the applied stress during use to inhibit or prevent fracturing in the high strain region.

Medical implants containing a temporary plasticizer, methods of producing such implants, and methods of using the implants in treating a disease, or ameliorating one or more symptoms thereof, in a subject are provided.
摘要:
A polymeric tube is positioned on a polymeric mandrel and then laser cut to form an implantable medical device, such as a stent. The method reduces contamination of the inner surface of the stent, which would be caused if conventional glass or metal mandrels are used, while simultaneously reducing damage to the inner surface of the stent due to the shielding effect of the polymeric mandrel.
摘要:
Medical assemblies with a releasable connection and methods of constructing such medical assemblies are disclosed. The medical assemblies generally comprise a stent, a catheter assembly having catheter body a balloon, and a releasable connection between the stent and the catheter assembly that releases the stent from the catheter assembly in response to enlargement of the balloon or when the balloon has been enlarged to an expanded configuration.

摘要:
The present invention relates to an endoscopic biopsy forceps (10) with an open central channel. The forceps include a sheath (20) having a proximal end and a distal end, a housing (50) connected with the distal end of the outer sheath, an open channel actuator control means (30) having a proximal end and a distal end and passing through the sheath, an operating means attached to the proximal end of the open channel actuator means, an open channel actuator (60.) attached to a distal end of the open channel actuator control means and having a first projection and second projection, a first jaw (40) having an actuator engagement projection and having a first position and a second position, and a second jaw having an actuator engagement projection and a first position and a second position. The first jaw and second jaw are movably connected to the housing, and when the open channel actuator is moved longitudinally along a body of the instrument, the first jaw moves between the open position and the closed position.
