Guidewires are essential medical tools widely used in healthcare. One of the prevalent issues today is the narrowing of blood vessels, which can lead to complications such as numbness in the limbs and respiratory problems. Controlling blood flow and preventing vascular blockages are critical, particularly in cases linked to obesity, sedentary lifestyles, and poor diets. Guidewires are utilized to open narrowed or blocked vessels and facilitate the placement of medical devices such as prosthetics, catheters, or stents within the body.
Specifications of Guidewires
Guidewires consist of two main components. The guide part is positioned on the patient’s body and acts as a pathway for physicians. These thin, flexible wires are primarily made of stainless steel or nitinol and are coated with PTFE (Polytetrafluoroethylene) to ensure smooth functionality. Depending on their size, diameter, material, and tip design, guidewires serve various medical purposes.
Applications of Guidewires
Guidewires enable the precise and safe insertion of other medical devices into the blood vessels. They are commonly used as guides for introducing radioactive contrast agents, catheters, balloon angioplasty devices, and more. For instance, in bypass surgeries, guidewires assist in accurately positioning catheters for injecting radioactive materials, ensuring effective treatment and procedural success.
