Benefits of technology

[0030]In another embodiment the apparatus has multiple stiffness characteristics throughout its length. In one embodiment, variations in stiffness are adjustable by the user. In one embodiment, the length of the different stiffness regions is also adjustable. In one embodiment, the diameter of the apparatus is variable along its length. In one embodiment, the diameter is expandable throughout its length. In one embodiment, these features are optimized to facilitate tactile feedback to the user so as to enhance the user's ability to advance the wire without prolapse, ensuring the intended trajectory is achieved, and provide external indication of the status or position of the apparatus.
[0031]In another embodiment, resistance of an applied current between two or more loc

Embodiment Construction

[0069]The present invention relates to systems and methods for enabling safe passage of guide wires to facilitate vascular access. The embodiments are applicable to any vascular access, whether percutaneous, surgical cut-down, or similar means, in which passage of equipment into cardiovascular structures is desired.

[0070]In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of some embodiments. However, it will be understood by persons of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, units and / or circuits have not been described in detail so as not to obscure the discussion.

[0071]FIG. 1A shows a guide wire 100 with distance sensors 101, 102, and 103. The guide wire loop is self-expanding and becomes larger if not constrained by the vessel wall. The looped tip is soft and atraumatic. The distance senso...

Abstract

A guide wire that has an atraumatic and flexible loop that expands within a vessel, with indicators that indicate the degree of expansion. The indicators are used to determine the degree of expansion through the use of radio-opaque markers, hydraulic, and electrical signals. The guide wire enables safe passage into target vessels while providing user feedback on inadvertent passage into side branches and diseased segments.

Description

RELATED APPLICATIONS[0001]This application claims benefit of and priority to U.S. Provisional Application Ser. No. 62 / 881,252 filed Jul. 31, 2019 entitled Device For Safe Guide Wire Placement, which is hereby incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to devices and methods to facilitate placement of a guide wire. More specifically, the invention relates to devices and methods to place a guide wire within a vascular structure with or without the use of adjunctive imaging methods such as fluoroscopy or similar equipment.BACKGROUND OF THE INVENTION[0003]For percutaneous medical procedures, there is a need to place devices, tools, or similar equipment into one or more blood vessels with the use of needles and wires. These techniques require direct insertion of the needle through the skin into the blood vessel, with or without imaging guidance (e.g. ultrasound, fluoroscopy, etc.), followed by passage of a guide wire into th...
