摘要:
This invention relates to a method of extending the shelf-life of constructs, in particular bioabsorbable stents, comprising semi-crystalline polymers by increasing the crystallinity of the polymers.
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:
A method and system for treating a bodily lumen with an implantable medical device, such as a stent, are disclosed. The device may be disposed within a bodily lumen and radially expanded by circumferentially deforming a tube-like section of the device. The deforming section may expand the lumen and the deformed section may support the lumen.
摘要:
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:
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.
摘要:
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 medical device such as a stent with a catheter, delivery balloon and an infrared energy source is disclosed. The infrared energy source heats the delivery balloon, and/or the stent to a temperature above body temperature, thereby increasing the flexibility of the stent such that formation of cracks in the stent upon its expansion is reduced or eliminated. Either the delivery balloon, and/or the stent may include an infrared energy absorbing material.
