AI Technical Summary

Benefits of technology

Enables precise placement and secure alignment of overlapping stent ends, ensuring consistent drug exposure and improved restenosis prevention by allowing for adjustable overlap lengths and configurations, including bifurcated stent assemblies.

Problems solved by technology

Currently however, precise multiple stent alignment wherein the overlapping stents have a preferred length of stent end overlap is difficult to achieve.

Embodiment Construction

[0031] While this invention may be embodied in many different forms, there are described in detail herein specific preferred embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.

[0032] For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.

[0033] As indicated above, the present invention is directed to a variety of different embodiments. An example of one such embodiment is shown in FIG. 1 wherein a stent assembly, indicated generally at 10, is shown. In various embodiments of the invention stent assembly 10 may be comprised of two or more stents or stent bodies 12 and 14 such as is shown in FIG. 2. Stent bodies may be any sort of implantable prosthesis such as stents, grafts, stent-grafts, vena cava filters, etc.

[0034] Stent bodies 12 and 14 may be balloon expandable st...

Abstract

A medical device and method of providing same, comprises a first stent body and a second stent body wherein the medical device is formed when the at least one first marker portion and the at least one second marker portion of the stent bodies are positioned in a predetermined alignment wherein the first stent body and the second stent body are aligned along substantially the same longitudinal axis and at least a portion of the first end region and at least a portion of the second end region of the respective stent bodies are overlappingly arranged to provide the medical device with a longitudinal length that is less than the sum of the first stent body length and the second stent body length.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] Stents, grafts, stent-grafts, vena cava filters and similar implantable medical devices, collectively referred to hereinafter as stents, are radially expandable endoprostheses which are typically intravascular implants capable of being implanted transluminally and enlarged radially after being introduced percutaneously. Stents may be implanted in a variety of body lumens or vessels such as within the vascular system, urinary tracts, bile ducts, etc. Stents may be used to reinforce body vessels and to prevent restenosis following angioplasty in the vascular system. They may be self-expanding, expanded by an internal radial force, such as when mounted on a balloon, or a combination of self-expanding and balloon expandable. [0004] Balloon expandable stents are typically disposed about a balloon which must be positioned a...
