Problems solved by technology

Having the guidewire coupled to the proximal connector also limits the maneuverability and manipulation of the guidewire
[0005] Also, the problem with existing pressure and flow pilot lines is that they require a complex assembly of many discrete parts
This complex assembly process has limitations on the design performance of the lead wire
The use of separate guide wires running along the length of the wire reduces the space available for more support cores and can result in poor solder joints with the conductive tape, electrical shorts due to insulation problems and breakage of dedicated wires. Many problems during use

Abstract

Intravascular devices, systems, and methods are disclosed. In some instances, the intravascular device is a guide wire having a core wire formed of multiple materials. For example, a sensing guide wire is provided that includes a core member having an inner section and an outer section surrounding the inner section, wherein the inner section is formed of a first material and the outer section is formed of a second material that is different than the first material; and a sensing element coupled to a distal portion of the core member. Methods of making, manufacturing, and / or assembling such intravascular devices and associated systems are also provided.

Description

technical field [0001] The present disclosure relates to intravascular devices, systems and methods. In some embodiments, the intravascular device is a sensing guidewire comprising a core wire formed from multiple materials. Background technique [0002] Heart disease is very serious and often requires emergency procedures to save lives. The main cause of heart disease is the buildup of plaque inside blood vessels, which eventually blocks the blood vessels. Common treatment options that can be used to open blocked blood vessels include balloon angioplasty, rotational atherectomy angioplasty, and endovascular stenting. Traditionally, surgeons have relied on X-ray fluoroscopic images, which are planar images showing the outline of the outer shape of the lumen of a blood vessel, to guide the procedure. Unfortunately, with respect to X-ray fluoroscopic images, there is a great deal of uncertainty about the precise extent and orientation of the stenosis responsible for the occ...
