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.

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.

Apparatus, method and system for cutting a polymeric stent including the use of a polymeric mandrel as a laser shielding device. The polymeric mandrel is allowed to roll freely within a polymeric tube that is cut into a polymeric stent.

Method to prevent stent damage caused by laser cutting

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.

An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. In one aspect, the stent includes a butterfly pattern to which connecting links are attached. In another aspect, the stent embodies a non-directional structure. One embodiment is a stent in which one or both ends are more flexible than the center portion. Also, the stent may have a non-uniform drug coating. Another embodiment relates to a stent having ends that are more radiopaque than the center portion.

Intravascular stent

A polymeric tube is positioned on a polymeric mandrel and then laser cut to form an implantable medical device, such as a stent. The assembly and 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.

Assembly for making a polymeric medical device

The apparatus and method use an optical feedback system to align a brush assembly with a stent strut. Once alignment is achieved, a coating is dispensed onto the stent strut via the brush assembly and the brush assembly is moved along the stent strut to coat the stent strut.

Method and apparatus to prevent stent damage caused by laser cutting

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.
