AI Technical Summary

Problems solved by technology

These markers are relatively time-consuming and expensive to manufacture due to the small size of the stent and the need to wrap the radiopaque wire multiple times around the struts on the stent, which is especially difficult in the obturator of the stent

Embodiment Construction

[0033]The present invention may be practiced by markers for use in vascular implants or other vascular devices, where the terms "vascular" and "vasculature" are used in their broadest sense to include any catheter or vessel in the human or other animal body tube network. A marker according to the present invention includes an elongated body formed of a biocompatible radiopaque material that enhances localization of the marker when using at least one imaging technique. The body has a first end, a second end, an inner surface, an outer surface, and at least two opposing edges extending between the first end and the second end and forming a boundary between the inner surface and the outer surface . The inner surface of the body defines a channel extending between the first end and the second end. In the first state, the body defines a gap between at least two opposing edges that enables unimpeded communication of the channel with the outer surface of the body. In the second st...

Abstract

A marker to assist locating a device such as an expandable stent within vasculature of a patient, including an elongated body formed of a biocompatible radiopaque material that enhances locating the marker when using at least one imaging technique. The body has a first end, a second end, an inner surface, an outer surface, and at least two opposing edges extending between the first and second endsand establishing a boundary between the inner surface and the outer surface. The inner surface of the body defines a passageway extending between the first and second ends. In a first condition, thebody defines a gap between the at least two opposing edges, the gap enabling unobstructed communication of the passageway with the outer surface of the body. In a second condition, the gap is obstructed to substantially prevent communication of the passageway with the outer surface of the body.

Description

[0001] This application is a branch of the patent application "Improved Radiopaque Markers for Vascular Devices" filed on March 11, 2014 (Application No.: 201410088730.1, Applicant: Depuy Xintes Products Co., Ltd.) Application. [0002] Cross references to related patent applications [0003] This patent application claims priority to US nonprovisional application 11 / 694,580, filed March 30, 2007. Background technique [0004] 1. technical field [0005] The present invention relates to implants and other devices that can be inserted into human blood vessels, and more particularly, to mechanisms for enhancing the tracking and positioning of stents and other vascular devices, particularly expandable implants. [0006] 2. Description of related fields [0007] Treating vascular diseases and defects such as aneurysms, embolisms, and other arteriovenous malformations is particularly difficult when they are located near critical tissues or where the malformation site is not r...
