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 stent with a stent locking element and a method of securing a stent on a delivery implement, such as a catheter are disclosed. The locking element can include coupling elements capable of being releasably coupled to one another. The coupling elements may be adapted to inhibit shifting of the stent on the delivery implement. In some embodiments, the releasably coupled elements may secure the stent on the delivery implement.

Methods of fabricating an implantable medical device from a tube or a sheet in an expanded or stretched state, respectively, are disclosed herein. The implantable medical device may be an endoprosthesis such as a stent. In one embodiment, the method may include radially expanding a tube about a cylindrical axis of the tube from a first diameter to a second diameter. The method may further include forming a pattern on at least a portion of the expanded tube. Additional embodiments may include forming a stent pattern on a stretched sheet from which a stent may be formed. In addition, a stent pattern may be formed on a tube that is formed from a stretched sheet.

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 of fabricating an implantable medical device, such as a stent, from a plastically deformed tube or sheet is described herein. The implantable medical device may be an endoprosthesis such as a stent. The method may include elongating a tube longitudinally along a cylindrical axis of the tube. The method may further include forming a pattern that includes at least one strut on the elongated tube. A further embodiment may include stretching a sheet along an axis of stretching. The method may include forming a tube from the stretched sheet. The method may further include forming a pattern including at least one strut on the stretched sheet or the tube.
