A disposable guide wire is a thin, flexible wire used in various medical procedures to navigate and guide medical devices, such as catheters or stents, through difficult or narrow pathways in the body, particularly blood vessels or the gastrointestinal tract. The guide wire helps in the precise placement of these devices during diagnostic or therapeutic procedures. It is termed "disposable" because it is designed for single-use to ensure sterility and reduce the risk of infection or cross-contamination.

Common Uses:

• Angiography: To guide catheters into blood vessels for imaging.
• Endoscopy: In gastrointestinal procedures for the placement of stents or dilation balloons.
• Cardiology: During interventions such as angioplasty or stent placement.

Materials:

• Guide wires are typically made from stainless steel or nitinol (a nickel-titanium alloy), which provides flexibility and durability.
• They may have a hydrophilic or hydrophobic coating to ease navigation through tight or tortuous vessels.

Types of Guide Wires:

1. Straight tip: Provides a direct pathway for less complex navigations.
2. J-tip (curved tip): Used for navigating more challenging or twisted pathways.
3. Hydrophilic-coated wires: These reduce friction for easier movement through blood vessels or ducts.
